Out of Sight, Out of Mind: What’s in Your Water? is a documentary where microbiologists and tank inspection professionals discuss the importance of having potable water storage tanks inspected and cleaned regularly. Currently the Environmental Protection Agency (EPA) has no regulations that require potable water storage tanks to be cleaned. We are hoping to raise awareness of this issue in order to change that.
We have been working on this project for over two years and it it time to raise some cash to finish it up. I hope you will be a part of this, please click here and find out how you can help! https://igg.me/at/whatsinyourwater/x/11623864
On October 15th 2014 the EPA held a meeting to decide if there should be a rule to require water storage tanks and towers to be cleaned and inspected.
The webinar is over but the EPA is still taking comments until the end of 2014. If you would like to make a comment on this issue, please send an e-mail to: SFIWebinar@cadmusgroup.com. Or take the poll below and I will send in the results at the end of the year. This is a chance to let your opinion be known!
My customers tell me they need less chlorine to meet water quality standards after I remove the sediment from water storage thanks and towers. Sediment enters the tank one particle at a time and eventually accumulates enough for bacteria, protozoa and even viruses to use it as a habitat, grow and become a serious health
problem. If proper inspections are not done to determine sediment levels, corrective action is seldom, if ever, taken. My opinion is that potable water storage facilities should be inspected inside and out every year, and a cleaning program to assure tanks and towers are cleaned every 3 to 5 years should be in place on all tanks. What do you think?
Since 1997 Ron Perrin Water Technologies has served the water utility industry providing state-of-the-art inspections with remote underwater cameras. Our inspection reports are the best in the industry, covering all state requirements for water tank and tower inspection and meeting all AWWA guidelines. Our inspections cover over 30 inspection points. Digital photography documents the condition of your tank, and our narrated underwater video lets you see first-hand what the inside roof walls and floor areas of the tank look like.
For those experiencing an EPA total coliform violation, our underwater inspections are a perfect place to start assessing your problem. Should accumulated sediment be found in the tank, our potable water dive crew can offer a cleaning solution that may be the only step needed to satisfy the Revised Total Coliform Rule requirement to take action. Accumulated tank sediment can be a safe habitat for bacteria, protozoa, viruses and other contaminants. Removing the sediment is often the only step required to comply with the Revised Total Coliform Rule**, in fact, our customers tell us time after time that their chlorine costs were significantly reduced after the tank was cleaned.
Diving in potable water is an art. Unlike offshore divers, potable water divers must be able to enter the water system without disrupting sediment on the floor of the tanks. Our divers are sealed in a dry suit so no part of their body touches the water. They are then washed down with a 200ppm chlorine solution to meet AWWA and state standards. The diver is then free to go into the confined space inside the water storage tanks. Underwater, the diver can do a more detailed inspection, or clean the loose sediment from the floor of the tank.
We are here to help you get it done! We offer the most choices for your inspection needs:
*Remote underwater camera (drop camera)
*ROV – Remotely Operated Vehicle (specially designed and only used in potable water)
*Diver inspection – For the most detail
*Basic state requirements covered with, or without, photos to meet budget needs
We have served over 500 water utilities since 1997. Our customers include municipalities, prisons, universities and military bases. They all have one thing in common – they wanted comprehensive documentation about the status of their water tank, with no water loss and no disruption in service.

**On February 13, 2013, EPA published in the Federal Register the revisions to the 1989 TCR. EPA anticipates greater public health protection under the Revised Total Coliform Rule (RTCR) requirements. The RTCR:
- Requires public water systems that are vulnerable to microbial contamination to identify and fix problems; and
- Establishes criteria for systems to qualify for and stay on reduced monitoring, which could reduce water system burden and provide incentives for better system operation.
- Click here for more information about the RTCR.
Revised Total Coliform Rule (RTCR) requires assessment and corrective action when there are indications of coliform contamination. Lets talk about Assessment and Corrective action.
Under the RTCR, there is no longer a monthly maximum contaminant level (MCL) violation for multiple total coliform detections. New revisions require systems that have indicators of coliform contamination in the distribution system to assess the problem and take corrective action that may reduce cases of illnesses and deaths due to potential fecal contamination and waterborne pathogen exposure. The rule says “The Distribution System” of course, what that means is, “The Water Utility Manager or Operator” is now required to assess the problem and take corrective action when there are indications of coliform contamination.
Getting started assessing the problem:
A tank inspection may be the best place to start with the assessment. Is the vent screen in place? Are there birds or insects in the tank? There are at least 12 steps to a water tank inspection and at least one of them should be to get a look inside the facility to see if there is sediment on the floor of the tank. Over time, sediment will build up on the floor area of almost all water storage tanks and towers. One to three inches is not uncommon here in Texas. Sediment is known to be a habitat for bacteria, protozoa and viruses. Inspection contractors can offer great documentation of the interior condition of water storage tanks with no disruption in water utility service. Using remotely operated cameras, inspection robots, or even potable water divers, high tech contractors can deliver great information about the water storage tank or tower. For information on in-service Water Tank and Tower Inspections, see our inspection page at www.ronperrin.com. For tips on doing your own potable water tank or tower inspection, see: Do your own potable Water Tank Inspection at: THE TANK DIVER blog.
Corrective action may be as simple as basic housekeeping. If you know the facility has never been cleaned there is more than a good chance sediment inside the structure needs to be removed. Again, a qualified diving contractor can save time, water and money by removing all loose sediment with minimal water loss or disruption in service.

Our tank cleaning customers tell us time and again that their chlorine use was significantly reduced after we cleaned their facility. With regular inspections and cleanings your likelihood of a coliform contamination are greatly reduced, if not completely eliminated.

UPDATE JULY 1, 2020.
In 2013 We Purchased a DEEP TREKKER ROV to use inspecting potable water storage tanks and towers. I am happy to report it is still working and doing a great job in 2020.
This video shows our first “Test Flight” in a clear-well and the second inspection we did on a ground storage tank. We added a safety rope to protect the tether and found the lighting system caused a little bit of glare when we went into darker parts of the tank, but it was reduced when we got closer to the inspection points we needed to look at. Overall, we found it to be a very good inspection tool!

We recently cleaned a potable water storage tower that had not been cleaned since it was built in the mid 1980’s. This facility was in compliance, it had been inspected once a year, but due to the fact that there are no set rules on when to clean water storage tanks in Texas it had never been cleaned.
We used a Celestron LED digital microscope to take a close look at the sediment removed from the floor of the tank. I posted what we found on my blog titled: THE CLEAN WATER TANK PROJECT at www.ronperrin.us. Due to the fact that rules on inspecting and cleaning potable water storage facilities vary greatly from state to state we may soon see changes in this area of Federal Regulation.
Currently most states do not have specific rules on when potable water storage tanks should be cleaned.
Please visit my CLEAN WATER TANK PROJECT blog and take the poll a few post down from the top. I would like feedback if you think the EPA should make a standardized requirement of cleaning and inspection of the nations drinking water tanks and towers.

Sediment being removed from a potable water storage tank
Photo: Sediment being removed from Potable Water Storage Tank.
The American Water Works Association recommends that tanks be cleaned at least every three years. Recent focus on pharmaceuticals in water systems have made more people than ever aware of contaminates that may be lurking in their water supply. Although pharmaceuticals in drinking water may be in the news the real threat is random bacteria and cryptosporidium spores.
The Threat of Bacteria-
Countless kinds of bacteria can make their way into a public water supply. Chlorine and other treatment methods are our first line of defense. When potable water storage tanks are clean small amounts of bacteria that survive the treatment process cycle through the system undetected and harmless due to the small quantity. Sediment in the tank can capture and harbor these small amounts of bacteria. The bacteria can start to grow hidden from chlorine deep in the sediment. Chlorine can even be overwhelmed and depleted if a nitrate eating bacteria is collected. As the bacteria continues to grow in the sediment month after month and year after year the threat to public health grows.
The Threat of Cryptosporidium
The threat of cryptosporidium outbreak is even greater with sediment in the floor of a water storage tank. Again Sediment can harbor bacteria, cryptosporidium and other contaminates. The best defense to insure a protozoa like cryptosporidium will not take up residence in your water storage system may be to keep the tanks free of sediment. In the Spring of 1993 over 100 people died as a result of a cryptosporidium outbreak that was directly associated with the Howard Avenue Water Purification Plant. This was the largest water born disease ever documented in United States history. It is estimated that over 400,000 people became ill with diarrhea.
Due to the fact that cryptosporidium is a protozoa parasite with a thick outer shell it is highly resistant to disinfectants such as chlorine. The best defense to ensure it will not inhabit your water system may be to make sure your water tanks remain sediment free. This will remove and habitat that small amounts bacteria or protozoa could lodge and grow in, Preventing possible public health problem in the most simple way. Keeping water storage tanks clean.
