Legionnaires’ Disease – and how to prevent it

Legionnaires’ Disease & what you can do to prevent it

Not that we don’t have enough on our minds with diseases these days, but Legionnaires’ Disease seems to be on the rise again as well. In 2018, there was an outbreak in Surrey, BC and in 2019 in Moncton, New Brunswick. In New Westminster, British Columbia, several people got Legionella during the summer of 2020 and some health experts are worried that prior COVID-19 infection could make a person more susceptible to Legionella.

lung diseaseLegionella bacteria are ubiquitous in water and soil, and multiply quickly in warm water (20-50?C). If you have a water cistern to store your household water in – as common in rural areas – and especially if the cistern is located in a sunny area, bacteria and algae can grow rapidly.

Jenni Green and Kalpna Solanki wrote a very informative article called “Preventing Legionnaires’ Disease” in June of 2021. Please read their full article published in Water Canada.

In the meantime, make sure your plumbing system is well maintained and your storage cistern cleaned and sanitized on a regular basis -we recommend at least once per year.

Groundwater License Application BC: Time is running out…

Are you a small business depending on ground water?

groundwater license application bc

If you happen to be a farmer, rancher or small business owner that depends on groundwater, you may want to investigate the new rules coming into effect by March 1, 2022.

About 16,000 existing non-domestic groundwater users in rural BC who have not applied for the license by the deadline, risk losing access to groundwater and recognition for their past groundwater use.

#1 Optimal cleaning of cisterns while saving tremendous amounts of water

Entering a cistern is dangerous

Entering a cistern without prior knowledge and training can do more harm than good. There are hazards in the manual cleaning of a cistern, including oxygen deficiency, uncontrolled increase in liquid level, and a slippery surface. Even professionals trained to work in confined spaces are at risk of these dangers. When an accident occurs, there will be expenses from damage to property, hospitalization bills, and worse, death of personnel.

Going inside a cistern – not so cool!

To eliminate risks of safety-related accidents, we at Environmental Cistern Cleaning Inc. employ environmentally sustainable cleaning methods that do not require technicians to enter cisterns. In other companies that perform manual cistern cleaning, water is removed from the cistern before the entry of the cleaner. After that, the cleaner will scrub all the surfaces using bleach; this will be followed by water refilling. Consequently, large amounts of water are wasted in this practice. With high demand for water in many parts of the world, water wastage, especially on this scale, that process just doesn’t seem right.

No physical entry needed

Since 2013, we have been carrying out deep cleanings of cisterns efficiently without physical entry. Draining the cistern is no longer needed. Therefore, we save a lot of precious water. We also do not use bleach in cleaning, thus avoiding harmful discharge of substances to the environment.

Poly cisterns or concrete cisterns?

Poly or plastic cisterns are widely used for residential water storage due simply to their affordability and ease of installation. They are generally lighter and easier to handle. They can be located underground, at ground level, or aboveground. The plumbing system for the plastic cistern is also easy to install, and different designs are readily available according to your needs. Plastic cisterns require less time for construction and need minimal maintenance. Furthermore, the strength and durability of the plastic piping reduce the risk of leaks, deformation, and breakage during catastrophic events such as earthquakes.

When is cistern cleaning needed?

Biological fouling and hard sediment build-up are the last things we want to see in water storage tanks. It’s a smart idea to clean and disinfect them on a regular basis to maintain a quality water source, whether groundwater or rainwater. Cleaning should be done at least once a year to remove sediment build-ups and sludges. However, more frequent cleaning can be performed if the water looks murky or smells unusual. If there are suspected contaminant intrusions such as entry of pests like rodents or insects or if there is a possibility flood water that may have entered, cleaning must be done. Lastly, after repair and installation of plumbing parts, you might consider cleaning and disinfecting to ensure all contaminants are removed from the system.

Environmental Cistern Cleaning Inc. at your service!

With our AquaSave plus™ technology, we can thoroughly clean cisterns with optimal water utilization. Using this sophisticated technology, we have already saved over ten million gallons of water. Our company’s green approach surpasses the traditional methods of cistern cleaning as we showcase safe, cost-effective, and reliable cleaning services.

Home Water Conservation

What you can do to conserve water

Everybody should know about Home Water Conservation. We came across an article by Courtenay McNally that gives a ton of good advise on how to conserve water. There are several methods you can apply from buying new appliances to changes on how one uses water. The article talks mostly about the UK, but the principles are the same, no matter where in the world you are located.

What If… I Never had my Cistern Cleaned?

What would happen...

If I never had my Water Cistern cleaned?

As water cistern and reservoir cleaning experts let’s examine what we would typically find in a rainwater collection cistern which hasn’t been cleaned in a couple of years.

Scavenger hunt findings in a cistern

First thing we typically notice is the unmistakable rank odor associated with pollen festering in the water – this glutinous stinky mess suspends in water and once it gets into the plumbing system proper, the taste and smell may remind you of a failed septic system…

This doesn’t help with water taste!

Further investigation reveals worms, wood bugs, and roof sludge predominating the findings on the floor of the cistern. Not to be outdone by a couple of 4 legged creatures that have gone for a one-way swim and lie motionless on the floor, legs pointing skywards.

A birds skeletal remains prompts the possibility of water borne diseases caused by dead rodents and other similar critters.

E-Coli, Cryptosporidium, Viruses etc., thrive and multiply in these oxygen deprived environments…, further exacerbated by the presence of decaying leaves, pine needles and bird poop…

What comes down, will go in...

Remember – whatever lands on your roof will eventually make its way into your water cistern!

Despite advertisers claims we have yet to see a truly effective roof-dirt filtering system. – All will allow some crud in there – and it needs to be removed.

Environmental Cistern and Reservoir Cleaning experts pioneered the technology and methodology and know how to clean water cisterns and reservoirs with close to zero Environmental impact.     

Without water wastage, and no chemicals used in the cleaning process, we clean cisterns with the least environmental consequences. We do not enter the confined space of a cistern, thereby removing danger to cleaning personnel. That in turn ensures No liability worries for the homeowner or hiring agent.

Environmentally Friendly

Environmental Cistern Cleaning. The Standard. After your water cistern is cleaned, a Hydrogen Peroxide disinfection treatment is available, disinfecting the cistern interior walls and stored water.  

In addition, as disinfected water moves through the house plumbing it also will disinfect and help to remove organic material coating the interior of plumbing lines and pipes.

A major added good health bonus

Hydrogen Peroxide oxygenated water plays a positive role for your health. Additionally, this oxygenated water also enhances your septic field operation.

You now know there is an almost 100% guarantee of the contents of your water storage cistern resembling the “before” pictures and descriptions below:

This is what can happen if you don't clean your water storage cistern...

A Time of Certainty


dance in water

After several months of lock-downs and isolation the province of BC re-awakens returning to a more normalized state, but there is one element which is constant: The need to ensure water supplies are drinkable and contaminate free. And today it is more important than ever to ensure your water is up to the task… hydrating you with germ free, uncontaminated water.

Build-up over Time

Little used water can build up Bacteria, E- Coli, Cryptosporidium, Viruses, in the water cistern storage tank or reservoir.

Whether you collect water from a well or a roof, the same issues apply, with the added concern for roof collection users of pollen entering the cistern. That pollen, if left unchecked and unremoved, will add a disgusting rank odor, akin of how a backed up septic smells. And yes, with our process we can remove the pollen and the odor!

Good Health or Illness?

A vital component to your health needs re-invigorating – the water you consume every day from your cistern or reservoir. This is the link between good health or, the possibility of contaminated water being the cause of illness.

Ask the Pro's

As specialists in the cleaning of water cisterns and reservoirs for the past 8+ years, our unique and proprietary Environmentally sustainable cistern and reservoir cleaning process is without equal.

How do we do it?

Our process starts with the complete cleaning of the interior of your water cistern, removing all the dirt, sludge, and any elements such as Iron, Manganese, Clay, from your cistern water. A thorough scrub down follows the physical removal of all the nasty stuff, and finally a complete disinfection using high strength Hydrogen Peroxide to ensure no contamination remains.

What is Hydrogen Peroxide?

uses for hydrogen peroxide

Hydrogen Peroxide is a Contact Sterilant, requiring no residual time to be effective. It is being used in hospitals and water treatment for many years in different parts of the world and forms the basis of all our disinfection protocols since our company inception in 2013.

After the cleaning of the cistern and the ensuing disinfection of the cistern and water, several things are noticeable: all odors are instantly removed, the water tastes great and is oxygenated (particularly good for your health) and as an additional bonus, all plumbing lines will also be disinfected, as Hydrogen Peroxide consumes organic material deposited in water lines over time and helps to remove it.

Additional Bonus

Additionally, for those on septic systems, through the naturally occurring oxygenation process, the Hydrogen Peroxide treated water will also enhance septic field operation.

Hydrogen Peroxide has been approved by the EPA (Environmental Protection Agency) as a Covid-19 disinfectant.

Final Piece of Good News

It’s a triple win for you – no costly water replacement (often the cistern cleaning cost is less than the water replacement), no interruption in your water service (you could even be showering while we clean your cistern!) and no Environmental damage.

Celebrate World Water Day

Value Water

Don't Take it for Granted...

The value of water is about much more than only its price. After all, water is what connects every living cell in our bodies. It has life and it continues through its own consciousness to heal & nourish, and it is fundamental to life itself in the making of life.

Water has memory and intelligence of its own. But imagine if your water storage supply is not well maintained – a cursory glance from time to time into your water storage cistern will not reveal its quality. Water quality is determined by cleanliness and the absence of Pathogens, E-Coli, Viruses, Cryptosporidium etc., which remain invisible to the naked eye, but replicate easily in a dirty water cistern lacking in oxygen and containing organic dirt.

Organic dirt is typically rotting leaves, pine needles, pollen, expired rodent carcasses, bird poop and roof dirt for rainwater collectors. And for well-water users count on sludge, manganese, iron, and rock flour making up the menu. This and more will be in water cisterns – despite all best efforts it is virtually impossible to keep all this nasty stuff out!

So, accept the fact that much of this is probably in your water storage cistern right now.

It needs to be removed, and we are the most experienced company best equipped to solve this issue. Property management companies, water treatment companies, farms, B&B’s, Canada’s Coast Guard, the Town of Lake Cowichan’s 1,000,000 gallon central water storage reservoir and the Village of Alert Bay are just a small sample of hundreds and hundreds of homeowners and businesses who rely upon our company’s water cistern cleaning service to ensure their water cisterns are in the best possible condition of cleanliness.

Make a point of celebrating your access to a good supply of what does you good.

And when the time comes that you need to have your water storage cistern cleaned for your ongoing good health – especially important in these challenging health times – ensure your immune system is receiving the best water possible, drawn from a cleaned and disinfected water storage cistern cleaned by Environmental Cistern and Reservoir Cleaning.

NOT a Glamour Business

Cleaning Cisterns is NOT a Glamour Business - but it is an Essential Service!

When it becomes necessary to have your water cistern or water tank cleaned, it is comforting to know that the company other homeowners trust and rely upon to get the job done right, has been providing this safe and Environmentally positive service to Vancouver Island residents and many Gulf Islanders for 8 + years.

Removing the need to empty and discharge the water prior to cleaning, and with no personnel entering the cistern (confined space liability issues…) and no Environmentally damaging chemicals used, the end result is this: All our customers experience a superbly cleaned water cistern, with the water still remaining inside and all the dirt removed!

Exceptions to the rule

Now there is an exception to the rule about not discharging the water. There are times when it may not be safe to retain the existing water – even after we have cleaned – so, at no extra cost, we do offer the option of a ‘Clean and Drain’ for those customers who would prefer this choice.


It feels like that to many of our hundreds of customers who often can’t believe the before and after differences of our cleanings.

Rural homeowners rely upon either well-water or rain catchment to fill water cisterns and tanks, but it is important to understand the function of a water cistern.

Functions of a cistern

In addition to acting as the water storage device it also functions as a dirt collector.

This dual function allows – in theory at least – clean water to flow throughout the house plumbing and leave the dirt behind. Unfortunately, it does not quite work out this way as any collector of water will tell you. Water cisterns and tanks harbor all manner of dirt, debris and organic material including iron, manganese, clay, pollen, roof dirt, decaying leaves, expired rodents, bird poop etc., with all of this eventually becoming part of the water storage contents i.e. the water itself.

No matter how expertly you screen and filter the incoming water, it’s a guarantee that dirt will be part of the cistern contents, the water you consume.

Best Cleaning Time

With spring on its way, right now could be the best water collecting and storage time: With wells recharging, wise well-users and rain-water collectors ensure their storage cisterns and water tanks are scrupulously clean ready for newly collected water.  

We are the professionals and experts – it is our proprietary cistern cleaning process developed in-house by our cleaning experts that produces these 5-star results.

In addition to our cistern cleanings, we offer disinfection of the cistern interior and the water, utilizing Hydrogen Peroxide.


Our disinfection process will also disinfect all the plumbing lines, oxygenate the water (great for drinking as it will also remove bad taste), and finally, enhance your septic field operation via the oxygenation it brings to the biological breakdown within the septic system process.

So, whether you want to experience great tasting water, a cleaned cistern, chemical free cleaning, or a “positive” for the Environment, you get it ALL from only one source: Environmental Cistern and Reservoir Cleaning.

Gulf Islands Water
Gulf Islands Water

Saltwater Intrusion

How to Protect the Aquifer & Your Well

Most islanders depend on well water for sustained water supply. But as the demand for water increases and more water is pumped from the aquifer new challenges arise with well water quality like sulfur taste and odour, low yields, or saltwater intrusion.

What is saltwater intrusion?

The freshwater aquifer near the coast or on islands like the Gulf Islands is becoming more at risk of saltwater intrusion. Especially in areas close to the coast with a high density of wells, the risk of seawater intrusion into the freshwater aquifer is higher.

Close to the coast, groundwater consists of a freshwater aquifer that sits above the higher density seawater with a transition zone (a mix of fresh and saltwater) in between. Mobile: click on image for description:

Saltwater Intrusion - Figure 1

Figure 1: Under non-pumping conditions there is an equilibrium established between fresh and saline groundwater at depth.

The aquifer is affected by

  • seasonal variations in groundwater levels,
  • amount of groundwater recharge from the rain, and
  • the rate of groundwater pumping.

When the pumping rate is too high or when the well is too deep, it can result in saltwater intrusion into the well.

Saltwater Intrusion - Figure 2

Figure 2:Pumping or other disturbances (e.g. sea level rise, reduced recharge) can lead to upcoming or inland movement of the freshwater-saltwater interface. If a single well is over-pumped or multiple wells are pumping, a large area of the aquifer may be impacted by salinity.

In fracture bedrock, saltwater can find its way to the well via a single fracture.

Saltwater Intrusion - Figure 3

Figure 3: In a fractured bedrock aquifer a single fracture can deliver saltwater to the well.

Once seawater intrusion occurs, changes in the aquifer may be irreversible or may take many years to recover.

Find out more about saltwater intrusion from the Government of British Colombia’s website which gives advice about Best Practices for Prevention of Saltwater Intrusion.

How can you protect your well and the freshwater aquifer?

Saline water is harmful to people with high blood pressure and can cause damage to soil and vegetation. An increase in island population or farming can lead to wells over-pumping and cause saltwater intrusion into the freshwater aquifer.

If you have issues with seawater intrusion into your well or a low water yield, find out more about the recommended well management practices and consider implementing the following solutions:

  • installing a water storage tank (cistern) and pumping in water from the well in the wet season (winter) for use in drier periods (summer),
  • installing a rainwater collection system, collecting rainwater during the wet season, and augmenting your well-water supply with rainwater during the summer.

We can help determine how big your storage tank should be to meet your water demand for gardening or hosting relatives and visitors during the summer.

The Incompatibility of Pollen, and your Water Cistern and Reservoir Collection System

This years pollen season – depending on where you live – has been behaving more like a pollen tsunami, beginning in February, and continuing through the latter part of June, with still no end in sight.

For rainwater collectors this is a time when uncertainty becomes certainty… The stink of pollen is confirmation that you have collected pollen somewhere in your water collection system.

We can, and will solve your problem.

Fortunately, we have the solution!

Since 2013 our cistern and reservoir cleaning service has helped to eliminate this problem by physically removing the offending, glutinous, slimy and filthy smelling pollen from water cisterns or reservoirs in addition to the regular sediment and sludge which has accumulated over time and is found in all water cisterns.

A recent comment from a colleague, that he didn’t know he had a septic system hiding in his house gutters, highlights the odor issue, because this is where pollen accumulates and coagulates before starting its journey into the water collection cistern or reservoir!

Once it enters the water system, pollen will collect on the water surface, before slowly sinking to the bottom of the collection tank.

Pollen-laden water then flows throughout the water system, plugging filters, leaving pollen residue in your plumbing lines, and generally making life unbearable, with the onerous smell encountered whenever taps are opened…

We hope you don’t have the same experience as Mrs. A, who recently called us for help. Her 5 cisterns had accumulated so much pollen, it was impossible for her to spend time in her home – the odor was so bad she had to find an alternative space until we came and eliminated the pollen and the smell – yes eliminated!

When things are getting really bad…

If you are familiar with our service, you will be aware of our whole premise of saving the water and not emptying the cistern when we do a cistern cleaning and disinfection.

Our unique and proprietary method of cistern cleaning without dumping all the precious water is still our top priority.

However, sometimes it is just not possible to save the water, because it is unsalvageable.

In these kinds of situations, where saving the water would not be to our customers’ advantage, we still perform our usual full cleaning (removing all the sediment and pollen, scrubbing the interior and disinfecting with Hydrogen Peroxide). But we would then complete the process utilizing our ‘clean & drain’ method, leaving your water cistern clean as a whistle, empty and ready for a water refill. This ‘clean & drain’ option is offered at no additional cost.

Not sure which type of cleaning you need? When our cleaning technician arrives at your home, he would inspect your cistern and advise as to the best option for you. Either way, a clean and disinfected cistern or reservoir will be ready for your use.

Please check our website at https://cleancistern.com/testimonials for more information and check out some of the comments from satisfied customers we have taken care of during the past 7 years of cistern and reservoir cleanings.

And for those of you who missed reading this article, that appeared in the Gabriola Sounder for the long July weekend in 2020, here is a pdf version.

Do you think that you have to drain all the water from your reservoir in order to clean it?

Think Again!

Watch our ROV at work and save your water!

We can clean your reservoir without any interruption in service to your customers and save your water at the same time.

Environmental Cistern & Reservoir Cleaning utilizes a custom built underwater Remotely Operated Vehicle (ROV) to effectively remove sediment, sand, and coagulated materials from the bottom of your reservoir.

Using a ROV is more cost effective than draining the reservoir and has lots of benefits:

  • No confined space entry required

The operator remains on the reservoir exterior and is guiding the ROV via a fiber optics controlled video screen.

  • No water contamination

As the operator doesn’t enter the reservoir there is no issue with water contamination.  All equipment that enters the reservoir is disinfected immediately prior to operation.

video recording

  • Recording of cleaning operation

As the ROV is guided to areas to be cleaned with two onboard cameras and 2 x 1000 lumen lights, the entire cleaning process (and potential issues with the reservoir) are recorded on HD. This video can be made available for the customer to examine.

  • Cost Savings

The ROV option provides a more affordable and faster way of reservoir cleaning than traditional options such as

  • employing a team of divers, or
  • emptying the reservoir to a virtually dry condition and then utilizing a confined space trained crew to enter while adhering to all WCB confined space protocols.

Budgets dictate the cleaning option which will be the most effective in terms of saving water and at the same time not compromising water quality in the reservoir.

  • Public Image and Water Conservation

We are proud in taking a leadership role in promoting water conservation and using methodologies which conserve water and benefits the “all”.

Our environmental cistern and reservoir cleaning methodologies – that were pioneered in 2013 – have saved to date more than 40 million liters of water, by not having to empty the water storage for the purpose of cleaning and then having to refill them with water drawn from the aquifer. It is an environmentally friendly and safe methods of cleaning cisterns and reservoirs  by removing all material in your water tank and/or reservoir such as sediment, sand, and coagulated materials.

To disconnect or not to disconnect the downspouts…?

Bee in pollen

Bee frolicking in the pollen on a flower.

Pollen Time is Here…

And to add to the problem, spring has sprung, and with it, many trees etc. are in bloom and with that comes the dreaded (unless you are a bee) pollen.

On top of it, drought conditions are here as well. As of April 1, 2020 we are in Stage 1 of Watering Restrictions (in Nanaimo), and we have the added directive to wash our hands frequently (due to the C-19 thing, you know what we mean, let’s not name it again…). Now how can you wash your hands (successfully), if you don’t have any clean water or hardly any water at all?

The Cistern Cleaning Conundrum of 2020…

We keep being asked: “Should I collect dirty rainwater, or bypass downspouts… and let the dirty rain water go to waste?”

With the likelihood of drought conditions lasting for several months, our advice…bring in the rainwater, the dirt, and pollen, the roof debris, – bring it all in…collect as much water as you can!

Dirt, pollen and all the other nasty stuff that will end up in your cistern – we’ll get rid of it when we clean your cistern, and we won’t have to throw away your water to do it!

We are famous for preserving the water when we clean cisterns, so go ahead and collect as much as you can!

discharge of dirt
Your garden can benefit from the discharge of dirt – let’s re-use that precious water

Water is going to be scarce again this summer and refills are expensive.

In addition to cleaning the cistern, if requested we’ll also disinfect it with Hydrogen Peroxide, which has just been approved as an effective disinfectant for COVID-19 by the EPA. No more dirt. No more smell. Safe Water.

Relax in the knowledge that no water will be wasted during the cleaning of the cistern. The dirty water we do have to discharge, can be utilized to water your garden (all organic).

Entering our 8th year in the business of cleaning water cisterns and reservoirs, we have gained an enviable reputation as being the go-to company for cistern cleaning.

Have a look at our review page and see what your fellow cistern users say about our service.

We’re ready when you need us…

So keep on collecting all that dirty rainwater…but remember to contact us when you want your cistern rid of all the dirt… we’ll leave you the water you preciously saved in a nicely cleaned cistern!

nicely cleaned cistern ready for your use
Nice and clean cistern – ready for your use

To keep yourself and our cleaning technician safe, we ask that you adhere to the social distancing requirement of 6 feet during the entire cleaning. Our cleaning technician will spray the cistern area with hydrogen peroxide before and after the cleaning process is complete. No person to person physical contact is needed at any time:

  • Cleanings can be booked online, via phone (250-247-9797) or email (info@cleancistern.com).
  • Cleanings are done with our enhanced disinfection protocol in place, and

Our first available open date is Friday April 10th and we are accepting cistern cleaning bookings for this date and into the future.


Yours and our safety is paramount and here’s what we do to ensure this.

As an existing customer of ours you may recall, we don’t need to have any person-to-person contact when we clean your cistern.

To this end we have put into place additional measures and safety protocols to ensure you and ourselves are not put at any risk whatsoever.

Here is a brief overview of what you can expect when we arrive.


It all starts with a complete disinfection of the immediate area of the cistern and includes an exterior disinfection of the cistern, any taps/ valves which may require turning off/on and any touched places by the cleaning technician before and after cleaning.

disinfection of equipmentWe use high strength Hydrogen Peroxide – a contact sterilant – for disinfection throughout the process.

At the conclusion of the cistern cleaning and removal of dirt and sediment from the interior, our cleaning technician will then disinfect the cistern interior and the remaining water in the cistern will be treated to ensure continuing safe use of the water.

EPA confirmation of Hydrogen Peroxide efficacy…

The Environmental Protection Agency (EPA) – under its Emerging Viral Pathogen program – last week released a list of disinfectants it said are qualified for use against the spread of coronavirus, COVID-19. Hydrogen Peroxide is included.

This means Hydrogen Peroxide is effective in preventing the spread of COVID-19.

Additional benefits of our Hydrogen Peroxide treatment include interior disinfection of plumbing lines flowing from the cistern throughout the house when flushed through with the treated water for a few minutes.

The good news continues…

Smell gone

Well owners experiencing “rotten egg” odors will be pleased to know our cleaning and treatment eliminates this, tout de suite!

And if you are one of the many, adding rainwater collection to your water mix – good news also! The benefits of rainwater collection far outweigh any downsides.


But if you live in an area with trees close by, you may find pollen is a problem certain times of the year exacerbated in windy weather. Blowing from the trees onto your roof and eventually entering your cistern with the rain as it washes off the roof…

The lesson here is to never forget to disconnect downspouts in pollen season!

Otherwise you will probably smell an odor once described as being like the smell of a backed up septic system! But don’t worry if this happens, we can remove the pollen from the cistern, still leaving the water in your cistern, and at the same time eliminating the smell.

Water Taste

If you choose to drink your cistern water after our cleaning and disinfection you will undoubtedly notice it tastes better and for many, the oxygenated water the Hydrogen Peroxide process creates is a welcome relief from previously uninteresting tasting water.

Anaerobic Environment

You see, when cisterns are dirty and contain decomposing leaves, sludge, dead critters both large and small, an anaerobic environment is created which becomes the perfect breeding ground for E-Coli, pathogens, cryptosporidium, and viruses in the water.

In addition to the danger created by the decomposing debris, water often has a flat and bland taste. The reason for this is, you are drinking “dead water”- all oxygen has been consumed by the organic materials that have collected over time in the bottom of the cistern or reservoir.

The end result is water that not only tastes bland and flat but has few if any health benefits.

Hydrogen Peroxide & your Septic System

We are often asked if the Hydrogen Peroxide will “kill” a septic system. Quite the opposite!

If you happen to have a septic system you will be happy to know your septic system will work better and with greater efficiency after our cleaning and disinfection, because a septic needs to have oxygen to ensure it is working to its optimum. Unlike bleach or chlorine, which will kill the septic field (or you), Hydrogen Peroxide will not do any harm to your system and you and it will keep on smiling!

Do it for your Health

So, whether you are an existing customer or thinking about if you should have your cistern or reservoir cleaned, this is probably one of the best things you can do for your health. Reliability, cleanliness, and providing you with the best and safest cistern or reservoir cleaning is what we are famous for.

Boost your Immune System

Corona-virus & your immune system…

So how does our Environmental Cistern and Reservoir Cleaning ensure your continued good health during this ongoing corona-virus outbreak?

corona virus preventionWe play a vital role in the ongoing assurance of good quality water from your cistern or reservoir, with additional benefits of disinfection using the premier “contact sterilant”, Hydrogen Peroxide.

This Hydrogen Peroxide disinfection will ensure your water health protection extends throughout your water system and water.

Added benefits of disinfection

This, in addition to removing odors & disinfecting the plumbing lines in your home even enhances the effectiveness of your septic system (which needs oxygen to operate at peak efficiency).

Another side benefit: water tastes great after our cleanings and disinfection with Hydrogen Peroxide, and ongoing benefits extend beyond taste, adding oxygen to your water for enhanced tastiness, safety, and protection!

Worth remembering: our immune system is the vanguard of our physicality.

An attention lapse could possibly cause serious health consequences.

It becomes vitally important to ensure our bodies have all the best elements guarding us and ensuring we can fight and guard against illness with a strong immune system.

Other major health benefits of our cistern and reservoir cleaning service include:

Our water cistern cleanings remove dangerous and immune weakening elements such as:

E-Coli, Viruses, Pathogens, Total Coliforms etc. and all, or some, can be present in dirty water cisterns and reservoirs.

Remember E-Coli breeds in oxygen-deficient water (anaerobic) and the only way to ensure safety, is to physically remove it, which is done through our cistern and reservoir cleaning process.

Water sources

When water is collected from a well, unwanted common elements entering with well water are manganese, iron, clay, nitrates, etc.

But for those who rely upon rainwater harvesting as part of their water collection process, there are different unwanted contaminants which enter a rainwater cistern collection system.

Include on this list: expired birds, pine needles, critters, mice, and even rats! Yes, we’ve removed these from a number of cisterns whose owners were totally unaware of this danger and were shocked when shown their presence during our cleanings… But let’s not forget everyone’s favorite…


Yes, that pungent smelling stink that will make you wonder if your septic system has backed up. For those who haven’t encountered pollen and are new to rainwater harvesting, this is exactly how pollen smells when left in a cistern more than a few days.

So maybe not the corona-virus cure but a necessary part of good hygiene starts with a clean cistern cleaned by Environmental Cistern and Reservoir Cleaning.

Don’t delay, call today 250-713-9797 or book online at  https://cleancistern.com/bookings

…After all, it’s your own health you need to take care of. Let us ensure you have the best tools for your body’s immune system. A clean and disinfected water cistern or reservoir from Environmental Cistern and Reservoir Cleaning is a good start.

Water Conservation Leadership

Water Conservation

Balancing water conservation, safety and solving turbidity problems in water reservoirs and cisterns is one of the specialties of Environmental Cistern and Reservoir Cleaning.

Boiled water advisories caused by turbidity have been a way of life for many Canadians, especially First Nations communities.

Quietly, our experienced team has solved this problem on multiple occasions.

Since 2013 the unique technology and methodologies pioneered by our company have proven effective in eliminating turbidity caused by silt and sediment on the reservoir floor.        

This Failure of dirt and sediment not being removed from reservoirs causes incoming water to stir up this dirt and circulate dirt laden water throughout the reservoir or cistern.

At Environmental Cistern and Reservoir Cleaning, we solve this problem by removing the underlying cause – silt and sediment build-up on the bottom of the reservoir or cistern.

reservoir cleaningOur developed and perfected unique environmental techniques and methodologies provide an ideal solution, dovetailing perfectly with the BC Climate Action Charter for cities and townships, communities, and central water system users to maximize water conservation during cistern and reservoir cleanings.

This new ROV technology enables us to remove sediment and silt from all sizes of reservoirs up to 5 million gallons capacity (depending on layout).

Our custom ROV (remotely operated vehicle) commissioned by us in 2019 has already been put to good use removing silt and sediment from The Town of Lake Cowichan’s 1,000,000 gallon reservoir, Village of Alert Bay central water reservoir of 250,000 gallons, in addition to Western Forest Products community of Holberg – 100,000 gallon reservoir, and The Haven Retreat and conference centre on Gabriola also 100,000 gallon reservoir.

All suffered the same problem; copious amounts of dirt causing turbid conditions and inhibiting effective water treatment for their respective water systems.

Our ROV reservoir cleanings have presented large water users with a solution hereto unknown and until recently, unavailable.

We discovered in some cases annual reservoir cleanings had not occurred because the then current methods always offered only two alternatives:

Either, drain the entire reservoir to empty, have a cleaning crew trained in confined space with all the attendant safety rigs, testing equipment, and personnel, enter the reservoir and manually clean.

Or, hire a team of divers to manually clean the reservoir- both methods exposing workers to dangerous working conditions in confined space and each coming with high liability potential.

Additionally, this aforementioned way of reservoir and cistern cleaning causes a huge Environmental impact!

For example: a 1-million-gallon reservoir cleaning actually uses two + million gallons of water.

One million gallons to be discharged into the environment to empty prior to cleaning, and another one million gallons to refill in addition to water required to hose down and clean the interior!

In the meantime, some communities in the past had their water supply “shut off” during cleaning, inconveniencing many people but also adding a potential fire department crisis if the reservoir water is used for fire and can’t be accessed until refilling occurs…

The Environmental Cost

Extrapolating these numbers across the province and its clearly apparent millions or possibly hundreds of millions of gallons of water are wasted anytime reservoirs are cleaned in this environmentally harmful fashion.

 7 years of proven success helping the Climate Action Mandate meet its goals

Our unique and proprietary environmental cistern and reservoir cleaning techniques ensure:

  • No emptying of the cistern or reservoir
  • No interruption of service
  • No personnel enter the reservoir
  • No confined space issues and insurance liabilities
  • No contamination issues
  • No chemicals used in the cleaning process
  • Lesser cleaning time and financial costs

Experience the Environmental Solution to Cistern and Reservoir Cleaning and see why we are the company of choice with our water conservation methods.

Since 2013, the founding year of Environmental Cistern and Reservoir Cleaning, these proprietary water conservation techniques have saved over 40 million litres of water from being discharged, and negating the usual refilling need of cisterns and reservoirs.

Putting this into perspective; these water savings are the equivalent of 80 million standard size water bottles.

And these – if laid end to end – would stretch for 17,000 kilometers, almost half-way around the world!

Big Solution + Big Water Savings = Big Environmental advantage.

Exclusively available from Environmental Cistern and Reservoir Cleaning.

Our aquifers need all the help they can get.

P.S. Reminder! Health Canada recommends the cleaning of water cisterns and reservoirs on an annual basis, check yours and you’ll see why this recommendation is suggested.

Happy Rainy Days!

Happy Rainy Days for the Westcoast

There is nothing like a good ongoing influx of rain barreling down the roof and gutters into the water cistern. That gurgling sound has recently bought smiles to faces all over the west coast to those who rely upon rainwater collection, and ground water to fill water cisterns and reservoirs.

But – with all this “liquid sunshine” comes a darker side.


But, continuing with good news – this is the ideal time to have us come and remove all the unwanted dirt, debris, and roof contaminants which will have made a home in your cistern.

Critters you don’t want in your cistern

Additionally, rural Well owners are reporting increased amounts of the usual manganese, iron and clay entering their water cisterns together with dirt-bearing well water.

Whether you collect your water from a well or via roof collection, no need to be concerned about losing all that  coveted water recently collected, instead we’ll remove all the stuff you don’t want in the cistern leaving you a sparkly clean and disinfected cistern with the precious water still in there!

However, leave it too long and this guy may appear!

sharksOur 2013 company mission statement is still as valid today as then: “We are in business to conserve water, using our unique Environmental Cistern and Reservoir cleaning methods”.

To date our unique environmental cistern cleaning methods are close to surpassing 40 million liters of water savings.

So how have we accomplished this?

The combination of not discharging the precious water prior to cleaning, together with eliminating the need to refill the water cisterns after cleaning them is unique to our process. Whether it is a 250 gallon cistern or a 2.5 million gallon reservoir –  our priority is always the same – ensuring the environment is unharmed and ensuring the maximum amount of water remains after cleaning.

Please consider selecting Environmental Cistern and Reservoir cleaning as your water cistern and reservoir cleaning company. Our water conservation contribution is only made possible by the hundreds and hundreds of customers who have selected us to clean their  cisterns since those early days… and during the past year we have expanded our unique cistern cleaning service to include reservoir cleanings – those big fellas – which are the lifeblood of a central water system.

Forward thinking by the Town of Lake Cowichan for their 1,000,000 gallon water reservoir cleaning, together with recently completed cleanings for the Village of Alert Bay’s 500,000 gallon reservoir and the Western Forest products’ 250,000 gallon reservoir in the community of Holberg all received high praise for the efficiency, affordability, and innovative use of our exclusive ROV technology and huge water savings.

All reservoir cleanings were completed without the need to dump the water, and no interruption in water service for their customers.

So now it’s your turn! Take advantage of our unique water cistern and reservoir cleaning.

Enjoy the quality of the remaining water in your newly cleaned and disinfected water cistern…

Sizes from 100 gallons to 5,000,000 million gallons and everything in between. Make it part of your contribution to our planet’s survival and your own health.

A simple phone call to 250-713-9797 is all it takes to get the ball rolling to arrange a cistern or reservoir cleaning. And yes, we are real people, so we can answer all the questions you may have… Or, if you prefer, our webpage https://cleancistern.com has a ton of good info as well.

Chlorine has protected our drinking water for a century – but its byproducts may be tainting it

For more than 100 years, chlorine has helped protect people across the country from dangerous pathogens that may otherwise lurk in their drinking water. But in some communities, byproducts of that same disinfectant may be putting residents in harm’s way. The article below is from the end of November 2019, but still current.

Manganese – Not just a nuisance, but a real health risk

It’s bad enough when you step into a dirty puddle of water and all your clothes get filthy. But at least – so you think – you can go home and wash them so you can look pristine again.

But what if the water coming out of your tap looks like this?

manganese in sinkNot so attractive anymore, eh?

Just today I came across an article in Water Online, which was originally posted  by the Mazzei Injector Company, LLC on May 21, 2018. In it, the author mentions that because many countries don’t list manganese as a contaminant – but rather only as a nuisance – it is not included in the list of things to check when monitoring water quality.

But when studies show increased occurrence of manganism (there is even a syndrome named after it!) which resembles Parkinson’s disease and a whole bunch of syndromes like slurred speech, lower IQ, loss of balance to name a few, occurring to people who are routinely exposed to high levels of manganese, then I am wondering why it isn’t listed as contaminant…?

Not being a scientist or doctor, I don’t want to scare anybody or misrepresent the facts, but I would like to encourage you to check it out for yourself. Please read the full article “The Hidden Dangers Of Manganese In Drinking Water” and make up your own mind.

What I can tell you, is that we come across a lot of manganese in cisterns – especially on Gabriola Island – and that it often looks rather nasty to say the least. Our cleanings do get rid of the manganese. If it’s in your well water, it will come back, but a yearly cleaning will make the world of a difference.

Clean & drain

When do we not save the water?






Now there are times when the water is so putrid and filthy (this can happen when the cistern walls have not been cleaned in a long time and a slime film has built up over time like on the image above) that it is necessary to completely scrub and clean the cistern as normal, but at the end of this process we then completely drain the cistern leaving behind a cleaned, emptied, and disinfected water cistern ready for new water…
clean & drainAt no extra cost!
This clean and drain process is available – at no additional cost – but please specify on the order form, or in conversation with our office, as this is a special order requiring additional equipment be brought to the job.

Fresh Water Aquifer found

Well here is for some good news for humanity:

Scientists have made a surprising discovery off the U.S. Northeast coast: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world.

fresh water aquifer

Scientists have identified signs of a huge aquifer off the U.S. Northeast (hatched area). Solid yellow or white lines with triangles show ship tracks. Dotted white line near shore shows edge of the glacial ice sheet that melted about 15,000 years ago. Further out, dark blue, the continental shelf drops off into the Atlantic abyss. (Adapted from Gustafson et al., 2019)

The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

If it can be shown that there are large aquifers in other regions, it might potentially represent a resource in places like southern California, Australia, the Mideast or Saharan Africa.

Drought Level 3

Level 3 drought declared

Below-normal stream flows and signs of drought in smaller streams have caused British Columbia to declare a Level 3 drought rating for the Fort Nelson area and for Vancouver Island and the Gulf Islands.

What actually means ‘Level 3 Drought’?

Level 3 drought conditions call for voluntary water-use reductions from all surface water and groundwater users. This applies to residents, industry, farmers, and municipalities.

What happens if it doesn’t get better (or if it doesn’t rain which is very unlikely)?

If voluntary reductions of water use do not maintain flows above critical levels, the province may consider regulating water usage under the Water Sustainability Act. Specific actions could include temporarily suspending water licences or short-term water approvals to restore flows to minimum critical levels in the affected streams.

Our method is less costly, faster, and – there is no interruption in your water service – you could even be showering while we clean!

When cleaning your cistern, it also makes total sense to disinfect at the same time. We use Hydrogen Peroxide for disinfection. Being a “contact sterilant”, HP is considered a water disinfection “standard” in many countries. Hydrogen Peroxide has none of the negative side effects in comparison to many alternative disinfectants. For more information, please go to our website https://cleancistern.com/news/ and search for hydrogen peroxide to find many posts.

Visit our website and book your cleaning now https://cleancistern.com/bookings/ and get ready to enjoy great tasting water from a clean cistern!

Internet not your thing? then call us at 250-247-9797, and we’ll advise, and answer all your questions!

How to clean your washing machine

cleaning serviceNow we know this is not the kind of post you might be used to seeing on our site, but we thought it rather interesting and it does talk about 2 areas we are completely into: water & cleaning. We also really like hydrogen peroxide, and you guessed correctly: one of the methods of cleaning and disinfecting your washing machine does involve the use of hydrogen peroxide.

Mind you the hydrogen peroxide we use to clean & disinfect your cistern is not the same kind you would get in a your drug or hardware store (there you typically get 2% or 3%). We utilize either 29% (technical grade) or 35% (food grade).

And now with no further adieu, an article by D L Mitchell, posted on March 19, 2019 on dengarden.com:

How to Clean and Sanitize Your Washing Machine Inside and Out

If this article got you all inspired to get all those areas of your home in tip-top-shape that have to do with water (like your water storage unit, called cistern) please don’t try to clean it yourself. There are professionals who do that without going inside the cistern… you guessed correctly again: give us – Environmental Cistern Cleaning – a call at 250-247-9797 – we’d love to help you with that.


Failed Well Water Tests

Bacterial Water Quality in Canada

The Droplet posted an interesting article about Bacterial Water Quality in Canada and failed well water tests today. The article is from VIQUA, the world’s leading supplier of residential and light commercial UV water disinfection systems as per their website (who want to sell their UV systems of course). The report is already 6 years old (and I am wondering how things are now), but I thought it was interested to see that BC was in 9th place, indicating low levels of failed water tests.

You can read the full article here:

Back in December of 2018, we posted another article about what to do with you UV system if you go away, which you may want to read up on while we’re on the subject.

Hydrogen Peroxide – Could this be the gardener’s best friend?

Another of the many reasons to use Hydrogen Peroxide if you garden or grow.

Normally our Environmental Cistern Cleaning posts highlight the benefits of our Environmentally friendly and safe water cistern cleaning technology. But today instead of highlighting all the wonderful cleanings we do for cistern users(!) we are going to focus on helping gardeners and plant growers overcome possibly the growers biggest issue:

Pests and how to get rid of them

in a Environmentally safe and economical way without resorting to the usual plethora of commercially available products. Readers of our posts will know how much we value the use of Hydrogen Peroxide as a disinfection agent for cistern cleanings, it is possibly without equal, but a question often asked is “what are other uses for Hydrogen Peroxide?”

So for you gardeners and plant growers here is important information which can help in all aspects of your gardening efforts. This information was derived from Zach, the author of the original articleHydrogen Peroxide for Plants‘, last updated on April 8, 2016 – but still as current as ever.

Hydrogen Peroxide for Plants

Hydrogen peroxide for plants sounds like pure madness, right? After all, why would you want to feed your garden vegetables with a solution that’s most famous for its use of disinfecting wounds? Well, to much surprise, this compound is actually the garden’s best mate.

That’s right, your garden can greatly benefit from hydrogen peroxide treatments! It might come at even more of a surprise to hear that it is completely compatible with organic gardens! So why is it so great? Well, you’ll just have to keep reading to find out, but how does natural pesticide, soil aerator and water cleanser sound for a preview?


Recognized by the United States EPA as an organic treatment for agricultural crops, hydrogen peroxide offers many benefits to gardeners.


When it comes to the cultivation of organic food crops, root worms and other soil pests are difficult to spot and even more difficult to treat for. Fortunately, feeding a diluted hydrogen peroxide solution to the infected plants will rid them of these soil-dwelling pests. Even a small amount will rapidly degrade external tissues and kill fungus, gnat larvae, cutworms, and parasitic nematodes upon contact. A diluted solution can also be applied as a foliage spray to control the populations of soft bodied pests, such as aphids and spider mites.

Soil Aeration & Root Rot Treatment

An over-watered garden can easily fall victim to root rot. This rapid deterioration of plant roots can establish itself after just 24 hours of moist, oxygen-deprived soil conditions. Again, hydrogen peroxide comes to the rescue! Watering thoroughly with a diluted solution, it will break down rapidly in the soil, boosting oxygen levels and expelling any anaerobic conditions.

Water Treatment

Many gardeners in urban areas with chemically treated municipal tap water choose to treat their water with hydrogen peroxide.


The Cistern Cleaning Conundrum

We keep getting asked what to do when the pollen season is about to start: disconnect the cistern to stop pollen getting into the cistern or keeping everything connected for maximum water collection….?

In recent years we would send out an email to our clients called something like “Pollen Alert”, but this year is particularly dry – water trucks are already running in April. So here is our message for 2019:

The Cistern Cleaning Conundrum of 2019…

Should I collect dirty rainwater, or bypass downspouts…and let the dirty rain water go to waste?

With the likelihood of drought conditions lasting for several months, our advice…bring in the rainwater, the dirt, and pollen, the roof debris, – bring it all in…collect as much water as you can!

Dirt, pollen and all the other nasty stuff that will end up in your cistern – we’ll get rid of it when we clean your cistern, and we won’t have to throw away your water to do it!

We are famous for preserving the water when we clean cisterns, so go ahead and collect as much as you can!

discharge of dirt
Your garden can benefit from the discharge of dirt – let’s re-use that precious water

Water is going to be scarce this summer and refills are expensive.
