Since 1997 Ron Perrin Water Technologies has been a leader in the inspection and cleaning of potable water storage tanks and towers.
We serve municipal water utilities, federal parks and prisons and private industry. We deploy underwater cameras or remotely operated vehicles to perform inspections of drinking water tanks.
Our methods save our customers millions of gallons of treated drinking water every year. If the facility needs to be cleaned our potable water dive team can remove tank sediment with minimal water loss and little to no disruption in service.
Sediment on the interior floor of a water storage tank is a breach and can be a serious threat to pubic health. Bacteria, protozoa and even viruses have been found to use tank sediment as a safe habitat.
Keeping your tanks clean will help keep your water system safe. Are your tanks and towers on a cleaning schedule? We want to help you keep your water tanks and towers clean and healthy! Do not allow dirt that builds up on the floor of your potable water storage tanks to be a safe habitat to grow Giardia, Legionella or viruses like Norovirus. Our water tower cleaning rates start at only $2,450.00. Affordable protection for your water storage tanks affordable safety for the people you serve.

The Centers for Disease Control and Prevention list these as the top 10 Causes – Outbreaks in Public Water Systems*
Today is Earth Day. Every year on April 22, trees are planted, litter is cleaned up, and awareness for the issues plaguing the planet are raised, in honor of the holiday, which is celebrating its 50th anniversary in 2020. The first Earth Day was on April 22, 1970. Environmentalists took to the streets with concerned citizens and pop culture icons, like poet Allen Ginsberg, who were asked to speak on behalf of Mother Earth.
The 1970s saw the passage of the most comprehensive environmental legislation in U.S. history, including the Clean Air Act, the Water Quality Improvement Act, the Endangered Species Act, the Toxic Substances Control Act, and the Surface Mining Control and Reclamation Act. In addition, just eight months after the first Earth Day, Richard Nixon approved the creation of a new organization tasked with monitoring the nation’s natural assets: the Environmental Protection Agency. You can find more facts about earth day at DO Something . ORG.
I manage a company that spends every day inspecting and cleaning water storage tanks and towers. Our goal is to save treated drinking water by performing required inspections without draining storage tanks. We use underwater cameras that allow us to enter the water system, inspect the tank, and produce a comprehensive report on its condition without disrupting water service. Over the years our “no water loss” inspections have saved tens of millions of gallons of treated drinking water.
Earth Day makes me think about what could be and how we could do more. In 2019 we inspected 651 potable water storage tanks and towers, but we only cleaned 105 of them. and that is a very typical year. Even on one of our best years in 2017 we inspected 863 facilities but only cleaned 95. There were hundreds more that needed to be cleaned but the decision was made not to clean the tank.
To understand why we only clean a fraction of the tanks that need to be cleaned and why that is a big deal, I need to give you a brief explanation of how water systems work. Your drinking water comes from ground water (aquifers), or from rivers and lakes (surface water). The most common disinfectant used is chlorine if it is from surface water it is also processed through different media at a water treatment plant. After the water has been processed it is pumped into a storage facility like a ground storage tank tank (GST), or an elevated storage tank (EST), where it sits and waits until you use it at your tap (60 Second Video Click here).
A few states have rules that require water storage facilities to be inspected every year but very few require tanks to be cleaned. Texas Administrative Code 290.46 (M)(1) requires all potable water tanks to be inspected inside and out annually. I guess it was assumed that when the inspection showed the interior floor was covered with sediment the utility would take action to keep it clean. That is not what is happening. Water regulations that keep us safe are much too complex for this article. The short answer is, as long as water testing is negative for coliform the water is deemed to be safe. Coliform is what is looked for to determine if microbes can live in the water. When it is not found the water is deemed safe to drink. About 7 years ago new rules under the Revised Total Coliform Rule (RTCR) required some additional monitoring of total coliform’s and E. coli.
There are now also requirements for assessments and corrective action when monitoring results show that public water systems (PWS) may be vulnerable to contamination.
In this case if no other breach can be found a good look at the water storage tank would meet the requirements for an additional assessment. If the results of the inspection showed that sediment was covering the floor of the tank, cleaning the tank could be the corrective action needed. Unfortunately, the complexity of the Revised Total Coliform Rule does not result in most tanks not being cleaned. In Texas, tank inspections are required but tank cleaning is often put off due to budget constraints or because those responsible don’t understand the dangers that can lurk in sediment.
The problem is as simple as a game of Hide & Seek. When conducting the required water testing a sample of water is taken from a tap on, or near, the water tank. Coliform must be found in the water to know there is a problem. Only a few feet away sediment on the floor of the tank may be hiding the contamination. A host of undetected microbes including bacteria, protozoa and even viruses, can use the tank sediment to get a foothold in the tank. Often left undisturbed for years, these contaminants continue to grow until they overpower the disinfectant in the tank. They can then be detected through required water monitoring but the damage is already done. The water system is compromised when testing finds too much Coliform in the system. Then boiled water notices are sent out to protect public health.
Sediment covering the floor of water storage tanks is a breach. It is as bad as a hole in the roof. Sediment can let almost any microbe or parasite that may have just passed through get a foothold in the water system, grow and become a public health problem.
Tank inspections are required in some states. However, even in those states tank cleanings still require a sales pitch unless the water system is compromised and testing finds too much Coliform in the system. That is often when we get the call.
Many well managed and well funded water utilities keep their water tanks and towers cleaned. This is why I came up with the tag line “Your zip code should not determine your water quality”. The fact is, like many other things in life, where you live affects almost everything, but it should not affect your water quality in the United States. Smaller systems that are not well-funded just need additional information about why keeping water tanks clean makes such a big difference. When tanks are clean the cost of disinfectants like chlorine goes down. The system is healthier and less likely to get a RTCR violation. In this case doing the right thing actually saves money and makes maintaining regulations easier.
This small, overlooked part of the world affects millions of people. Keeping tanks clean is just basic housekeeping and should be the standard at every public water utility. Unfortunately, it is not the first thing thought of when violations occur. The knee-jerk reaction is to add more disinfectants. However, when the maximum residual is reached, the decision is often made to change disinfectants. This just adds up to more time and money wasted if the tanks have not been properly inspected or kept clean.
Thanks for staying with me this far. This is where I decided to DO SOMETHING.
The Ron Perrin Clean Water Tank Project Inc. was established to educate water utility managers about the importance of keeping tanks clean. Help me get water utility managers to think about cleaning storage tanks FIRST instead of Last or not at all! We are producing a documentary, promoting our blog and creating literature on the importance of keeping tanks clean. Our non-profit is registered and can be supported through the SMILE program at AmazonSmile. Search for the “Ron Perrin Clean Water Tank Project Inc.” and you can round up the change on your Amazon Purchase to allow us to get the change and help us DO SOMETHING that needs doing. Together we can make a change by improving water quality for more people.
Sediment on the floor of your water storage tank is a Breach in your system. The more sediment you have in your water storage tanks the bigger your risk for having a water-related contaminant issue. Tank sediment builds up over time and can provide a wide range of contaminants including viruses a way to get a foothold in your water system. The tank sediment can provide a safe habitat allowing a small number of bacteria or viruses to quickly grow into the billions.
The Centers for Disease Control and Prevention recently released a guidance and fact sheet on transmission of the novel coronavirus in water.
THE GOOD: The agency stated: “Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19.”
THE BAD: The fact is other viruses are found in drinking water, in fact you will find them in the top ten contaminants. Including Hepatitis A, a vaccine-preventable, communicable disease of the liver caused by the hepatitis A virus (HAV), and Norovirus. A very contagious virus that causes vomiting and diarrhea. Conventional water treatment methods should also prevent these viruses from contaminating drinking water systems but they remain in the top ten of drinking water-related contaminants.
Here is the top ten list of Water-related Diseases and Contaminants the CDC found in in Public Water Systems.
The United States has one of the safest public drinking water supplies in the world. Over 286 million Americans get their tap water from a community water system (1). The US Environmental Protection Agency (EPA) regulates drinking water quality in public water systems and sets maximum concentration levels for water chemicals and pollutants.
Sources of drinking water are subject to contamination and require appropriate treatment to remove disease-causing contaminants. Contamination of drinking water supplies can occur in the source water as well as in the distribution system after water treatment has already occurred. There are many sources of water contamination, including naturally occurring chemicals and minerals (for example, arsenic, radon, uranium), local land use practices (fertilizers, pesticides, concentrated feeding operations), manufacturing processes, and sewer overflows or wastewater releases.
The presence of contaminants in water can lead to adverse health effects, including gastrointestinal illness, reproductive problems, and neurological disorders. Infants, young children, pregnant women, the elderly, and people whose immune systems are compromised because of AIDS, chemotherapy, or transplant medications, may be especially susceptible to illness from some contaminants.

Bacteria, protozoa, invertebrates and viruses all love heat. The last few years we have continued to see record-breaking heat waves again and again. Keeping water distribution tanks clean should become more of a priority. Several of the top ten water system contaminants listed by the CDC can use the soft sediment that builds up on the floor of water storage tanks as a habitat to grow and become a public health problem. Removing sediment removes the habitat that contaminants can use for food and shelter allowing rapid growth.

Since 1997 Ron Perrin Water Technologies has been cleaning water storage tanks and towers. If you are a water utility official please call us for a free quote today,
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.
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!
