Reservoir Cleaning

That won't blow your budget


With 49 million liters of water not having to be wasted for cleaning purposes since our company’s start in 2013, we are proud to be part of the BC governments’ climate mandate.


Utilizing the latest ROV technology, no human entry into the confined space of a reservoir is needed, hence we can guarantee operator safety when performing a sediment removal.


Before this new ROV technology was available, divers had to be deployed into the reservoir. We are able to achieve tremendous savings in man-hours which can be passed on to clients.

Does your reservoir need cleaning?

If you haven’t had your reservoir cleaned in the last 2 years it most likely needs cleaning.

Watch our short video to see our ROV in action.


our Specialties


With our AquaSavaPlus technology we can remove the sediment off the floor of your reservoir without having to remove the water.

No Interruption of service

You can go about your regular day - no interruption of service to the homes or businesses your reservoir is serving water to.

No Confined Space Entry

As we employ the latest robotic equipment, no personnel needs to enter the reservoir.

Affordable Service

As we do not go inside the tank, no costly confined space entry protocols have to be enforced. Also no need to hire divers.

Our Strata and council were very please by the service from Environmental Cistern Cleaning and will definitely have them back for our next cleaning and will also pass along their name to our neighbours.

Beverly Jeffrey August 2, 2023

Great experience.


This company is great - always reminds me when it is time for a cleaning. Always on time and job finished quickly. I have used them for years and will continue to do so. Also one of the few businesses to NOT increase their fees since the pandemic - I appreciate that!

Joy Strandquist April 17, 2023

Had two 2,500 gallon tanks done by Enviro. Hadn't been done in 15 years. The tech was competent and pleasant to deal with. Tanks got cleaned and we'd use them again!

I am generally satisfied with the work that Environmental Cistern Cleaning did on my house. I have a small poly cistern inside my well room and a large concrete cistern buried out in the front yard. When I called Geoffrey, he was very professional. In his alluring, gentlemanly accent he took pains to ascertain as much information as possible (if memory serves, he also spoke with my water system person to get a few details). Geoffrey listened carefully, answered questions clearly, and provided me with a written quote in a timely manner. When I asked to reschedule the work a couple of months down the line, Geoffrey obliged me and his technician came to do the work at the appointed time, on the appointed day. My only (very minor concerns) is that, despite our discussion about disinfection with hydrogen peroxide (which wasn't supposed to leave any residue in the water), the tap water did have an unusual chlorine-like aftertaste for about a week after treatment, but it did go away. The other minor annoyance was the technician making a bit of a mess in my pump room; I didn't mind helping him tidy up some of the water, but, having been bitten by the expense of that area being flooded before, I would prefer it if the technician were more careful near the carpeted area in the future. Having said this, I am completely and utterly satisfied with Geoffrey's friendly demeanour, professional operation, and timely delivery of services. I highly recommend Environmental Cistern Cleaning to all homeowners.

The job was completed efficiently and Will even came back after his work day the next day to fix an airlock. We really appreciated that.

Debra Shogan March 19, 2022

I had a chance to meet Geoffrey the owner of Environmental Cistern Cleaning and was able to have him inspect our cistern. On inspection he noticed a buildup of clay matter in the tank. So, we had Geoffrey send a service tech to clean it. The tech was professional and personable, very easy to deal with. He also did an extremely great job in cleaning the cistern. My wife and I would highly recommend this company to anyone that needs cistern cleaning. Thank you Geoffrey and Sabina for your complete honesty in dealing with us, and doing a professional service.

Santino November 11, 2021

We have used Environmental Cistern Cleaning for years now and have always had high-quality, professional service. And they are genuinely lovely people! Highly, highly recommend.

Jason Vantomme September 17, 2021

Wonderful service.. fantastic people. I would deal with again

Micheal Rawlins September 14, 2021

The team at Environmental Cistern Cleaning are excellent. They gave me more information than I will ever remember before the appointment, showed up on time and did an amazing job. I highly recommend this company if you need your water tank or cistern cleaned.

Corinne Smith September 8, 2021

Geoffrey took the time to explain the service, the requirements and the process he and his team used. He patiently answered many questions I had, and offered up advice on my system and some changes I was considering based on his experience. Very much appreciated and knowledgeable. His crew showed up on time and did the job right the first time.

Henry Tkachyk January 24, 2021

Kaman did an excellent job cleaning out our very dirty cistern. Hydrogen Peroxide was the way to go. After doing some additional research, I went ahead and treated our well with the Technical Grade H.P. and that solved our iron bacteria issue.

Dennis Smith November 8, 2020

After a thorough conversation with Geoffrey, we decided to go ahead with the cistern cleaning. The technician was polite, explained the procedure and got the job done quickly. Our water quality immediately improved and we felt confident that we had solved the problem of smelly, stained water. thanks!

Deborah Pike August 27, 2020

Good job, very clean.

Alana Reay July 29, 2020

“Prompt and Professional” We had our cistern cleaned by Environmental Cistern Cleaning and could not have been happier with their prompt and professional service. The cistern was cleaned and disinfected without wasting water and with no interruption to our daily routine. The work was completed on time and for the quoted estimate. We are very pleased with all aspects of our experience with ECCI including the ease of scheduling and communicating with the company personnel, as well as their knowledge and professionalism. We will certainly use them again next time and recommend their services to anyone who needs their cistern to be cleaned!! Graz&Steve

Grazyna Chrobok June 14, 2020

My wife and I had Kaman in to do our cistern in April. We could not have been happier with the service, or the end result. He answered all of our questions, kept us informed as the job went on, and even stuck around after to help the water hauler get set up. I will absolutely use them again next time, and would recommend to anyone having their tank cleaned

P Lunn April 21, 2020

We are VERY happy with the service that we received!! The owner spent time on the phone with me answering all my questions, as we have a horse boarding business which supplies water to lots of animals. The fellow who did the cleaning was very professional, and really took the time to do it right, and he showed me everything he was doing and why. Our large cistern tank looked brand new once done. We will definitely be getting you back every year to clean our tank. Thanks for a job well done!

Coral Sawkins April 8, 2020

ECC cleaned our 1250 gallon above ground cistern after many years with no cleaning. Everyone I dealt with was professional and appeared to do his/her work competently. I don't hesitate to recommend the company based on my one time experience.

jon snipper September 4, 2019

Unparalleled experience and service! They have been cleaning our cistern since their first year of business. We've never had anything but top-notch service and results. They do whatever it takes to get your cistern looking like new, and the water tasting as fresh as can be.

Peter Koppenaal August 2, 2019

WE have used Clean Cistern twice now, and have been extremely satisfied on both occasions. Kaman is very thorough, and the proof is in the results!

John Rodgers November 23, 2018

Not only does Environmental Cistern Cleaning do an excellent job but they contribute their services to worthwhile causes at no charge. Kaman was efficient and professional and I was very pleased with the results.

Kaman, who did my cistern, is a fine fellow, a good worker. He took time to do the job well, and even came back to do a fine sweep a week later, as some material had settled out to the bottom (my tank is 5500 gal). It was expensive to do, but my water is noticeably cleaner - clear, instead of tinged pale yellow, so I'm happy I had it done.

Mary Bowman September 13, 2018

It is great to know that my cisterns are as clean as can be, and it is all done without losing any precious water! A wonderful service and great people! Thank you!!

Vicki McDonald June 20, 2018

We had great service, the fellow came on time and was very helpful with describing what he needed to do and the process. Cleaned up after himself and let us know when he would be back to vac again after any sediment had settled. On his return visit again was on time and when finished let us know he was done and gave us his card in case we had any issues We would recommend them to anyone who needs their cistern cleaned

Richard Samas April 19, 2018
