Environmental Cistern Cleaning Inc. was initially formed as a partnership between Geoffrey Montgomery-Swan and Sabina Montgomery-Swan under the name of CleanCistern.Com and commenced business on April 11th, 2013. The company has since incorporated (as of February 1, 2016), but everything else has remained the same.

The company was created to take advantage of the need to have water cisterns and tanks cleaned with an environmentally safe and chemical free cleaning process, and without causing liability issues which were present with the then current methods of cistern and water tank cleaning.

Our service area currently covers Vancouver Island and the Gulf Islands of British Columbia. We have also serviced clients in the lower mainland. As our equipment is designed to be light-weight & portable, we also offer a fly-in/fly-out service to very remote areas.
