Water Tank Inspection

One of the most important things a water utility can do is an annual water tank inspection on all potable water storage tanks in the system including both ground and elevated storage. Without proper inspections, the tanks often go out-of-sight and out-of-mind. Inspection should include all AWWA inspection points and a good look at the interior. The traditional way to do this is to remove the tank from service and drain the water. This is extremely labor intensive and often requires smaller communities to be without water for an extended period of time.

Custom water tank underwater inspection camera and lighting system.

Water tank inspection contractors often use a remote underwater camera, a remotely operated underwater vehicle, or a commercial diver to perform this task. Following AWWA guidelines all equipment is washed down with a 200ppm chlorine solution before entering the water system. Once inside the underwater cameras can get a good look at corrosion and sediment that may be hidden underwater. Using an inspection contractor allows the treated drinking water to stay in the tank and any disruption is reduced to a bare minimum.

In Texas, all potable water storage tanks are required to be inspected inside and out. Texas Commission on Environmental Quality (TCEQ), mandates that under Texas Administrative code 290.46 water utilities in Texas are required to perform an annual inspection of each storage facility in their system with a utility employee or a contracted inspection service. The basic inspection form can be found here: TCEQ Tank Inspection Form.

On the form under WATER QUALITY,” the form asks if there are Insects, floating debris, or sediment on the bottom of the tank. While you may be able to see the bottom on smaller tanks, the majority would need to be drained or deploy some type of underwater camera to get a good look at the floor. Inspection contractors like Ron Perrin Water Technologies, Inc. offer some innovative tools to get inspections done with no disruption in service at all. From remotely controlled underwater cameras that can get a good look to see what is on the floor of the tank, to Remotely Operated Vehicles (ROV) that are able to swim to the back of a larger facility so no part of the tank has been unchecked. All of our reports include photos of every inspection point and interior photos and video. With our specially designed camera and lighting system, we are able to get a good look at the interior roof. This is a key inspection point and often has the most corrosion that we find on the facility. Our underwater camera is lowered into the tank taking a look at what is going on just under the waterline and lower wall areas. Finally, the floor comes into view and we are able to estimate sediment levels in the tank. Larger facilities often need to use the ROV to reach the back side of the tank or look at a specific area thought to have a problem.

It is extremely important to monitor sediment levels in water storage tanks. Sediment can be a breeding ground for bacteria, protozoa, and even viruses. When our inspection discovers sediment is starting to build up we can document what is going on with underwater photos and video. We then include a proposal to send our potable water dive team back to remove the sediment. This can also be done with minimal water loss and no disruption in service.

Sediment is being removed from a small ground tank by a potable water diver working inside the tank.

Are you breathing right?

According to a new book on the subject, most people are not doing the common task of breathing correctly. James Nestor is the author of the new book BREATH: The New Science of a Lost Art. According to Mr. Nestor by fixing our breathing we can fix many if not most of our physical and psychological ailments.  Nestor is a science journalist, his book Breath: The New Science of a Lost Art, recently spent 18 weeks on the New York Times bestseller list. I heard him on the Ten Percent Happier with Dan Harris podcast a few days ago. Take a listen to the podcast and see what you think. I thought it was very interesting so, I ordered the book and may post about it again after I have time to read it.

The podcast made me think. Air is important to human life, but still, most of us do not think much about how we get it. Turns out how we get it is very important but not many of us think about this part. Water is important and unfortunately, my company sees water systems every week where not enough people are thinking about them too much either. The little things matter. A vent screen goes missing after a storm or the tank develops a small breach due to corrosion. Small things can make a big difference. If your water tanks are on a cleaning schedule of any kind they are being maintained better than the majority of small systems. We come across water storage tanks every week that may be inspected every year to meet state regulations but are rarely if ever, cleaned.

All water tanks should be on a schedule to be cleaned every 3, 5, or 10 years. If your last water tank inspection did not document how deep the sediment was in the tank, your next tank inspection should. Our water tank inspections use an underwater video camera and lighting system so we can document what is really going on in your tanks with NO Disruption in service.

By having a well-documented inspection done you can keep up with what is really going on in your water storage tanks.

Having your tanks on a cleaning schedule will let you breathe a little easier too.

Working in potable water with no disruption in service.

Potable water diver entering GST

Our potable water dive crew is one of the best ways to keep your water storage tanks clean and healthy. The diver is sealed in his own environment and washed down with a chlorine solution to meet USEPA and state water quality standards. The diver is then able to move about the tank freely allowing him to do an inspection, clean the floor or perform other needed tasks. Check out our Facebook page to see a video of this tank being cleaned https://www.facebook.com/ronperrinwatertech.

Since 1997 we have been inspecting and cleaning water storage tanks and towers. Our methods and procedures save millions of gallons of treated drinking water every month by allowing tanks to be inspected and cleaned while they remain in service.

Custom-built underwater camera and lighting system

Our custom-built underwater camera and lighting system is one of the best values in the industry allowing tanks to be inspected inside and out with no human entry. This saves water utilities time and money while delivering an informative inspection report that exceeds state documentation standards. An annual inspection that covers the interior of the tank all the way down to the sediment levels is one of the best ways to keep up with the health of your water system. For larger tanks, we also have several Remotely Controlled Vehicles (ROVs) that we can deploy when needed. The ROV is also equipped with an underwater lighting system that has the added benefit of being able to navigate to the rear of a large tank or look at specific areas you may want to document. You can see a short video of our ROV service here: https://youtu.be/21z5nbx2-R8. If your ground or elevated storage tanks need to be cleaned our potable water dive crew is a great way to get that done with no disruption in service and minimal water loss. If you have a standpipe with a water depth deeper than 50 feet we recommend WALLIE.

Wallie is what we call our standpipe cleaning robot. Capable of working at depths of 165 feet Wallie can stay down as long as it takes to get the job done right. He is equipped with two video cameras and a lighting system to allow the operator to see what he is doing. This also allows us to record the cleaning and document the final result for our customers. You can see Wallie in action here: https://youtu.be/7bFqEW_x_fo. If you have a water storage tank please give us a call to get a free inspection or cleaning quote. Our toll-free number is: 1-888-481-1768, in the DFW area call: 817-377-4899 or e-mail Robert at perrinsales@gmail.com.

According to an article published in USA TODAY, dead snakes and mice, toxic sludge: How pathogens go unnoticed in many of America’s water towers.

The article states that many water towers have been left to fester, sometimes making people sick. The federal EPA has been looking into uniform regulations for years.

When is the last time you took a look inside your water storage tank? Our company “RON PERRIN WATER TECHNOLOGIES, INC.” inspects about 800 tanks a year. Every week we find a tank or two that have never been cleaned. According to this article published in USA TODAY May. 21, 2021, by Kyle Bagenstose, there are also tanks that are seldom if ever inspected too.

In March of last year, residents in the small coastal community of Delray Beach, Florida, noticed something strange about the water coming from their taps.

It was discolored. Smelly. Flecked with bits of dirt.

“You looked at it, and it wasn’t clean,” resident Reeve Bright said. “You started seeing the ice coming out of the ice maker, and you’re going, ‘What the heck is going on? There is stuff in the frozen water.’”

Complaints to the city prompted the discovery of sediment that had accumulated inside one of the city’s massive water storage tanks. The sediment had traveled along with the water into cups, cookware, ice trays, and bathtubs.

It wasn’t a freak occurrence or the result of some unavoidable problem. An investigation found no records that the tank had ever been cleaned since it was built.

In 1972.

Inspection Contractor for 30 years!

I have been a Water Tank Inspection Contractor for over 30 years. Starting in 1991, my first inspections were done on my days off while still working as a full-time Texas Peace Officer. I was a principal at Tank Diver Inspections (TDI) a startup company that failed. Form 1994 to 96 I was director of marketing at U.S. Underwater Services in 96 I was promoted to Director of Operations. In 1997 I established Ron Perrin Water Technologies and devoted myself to developing the best methods to inspect and clean potable water storage tanks with NO DISRUPTION in water service. We incorporated in 2020. We offer the best inspection in the industry. We are here to serve you! We offer three different water storage tanks inspections, all include underwater documentation with our underwater video cameras and lighting systems.


Our Company
 provides nondisruptive water tank inspections on potable water storage tanks in Texas and 14 other states. In Texas, our tank inspections meet all requirements found under Texas Administrative code 290.46 (m)(1) -Each of the system’s ground, elevated, and pressure tanks shall be inspected annually by water system personnel or contracted inspection service.  We want to be your Contracted Inspection Service.

In Texas you must examine your ground, elevated, and pressure storage tanks at least once every year to make sure they are in good working condition. Tanks should be inspected no later than one year after the last time you checked them.

Ground and elevated tanks are required to be inspected inside and out every year. Pressure tanks also need to be inspected on the outside every year and if they have an inspection port they are required to have the interior inspected once every five years. The grounds and facilities shall be maintained in a manner so as to minimize the possibility of the harboring of rodents, insects, and other disease vectors, and in such a way as to prevent other conditions that might cause the contamination of the water.  (1) Each of the system’s ground, elevated, and pressure tanks shall be inspected annually by water system personnel or contracted inspection service.    (A) Ground and elevated storage tank inspections must determine that the vents are in place and properly screened, the roof hatches closed and locked, flap valves and gaskets provide adequate protection against insects, rodents, and other vermin, the interior and exterior coating systems are continuing to provide adequate protection to all metal surfaces, and the tank remains in a watertight condition.  

It is extremely important these facilities be properly inspected, we recently inspected a ground storage tank that had a damaged vent screen, inside on the floor of the tank we found two dead rats. Not what you want in a water tank that you are drinking out of. Birds and insects are much more common, it there is a hole in the vent screen that you can put your finger in you can bet there are insects in the tank. It the hole is big enough to put your fist in there is a good chance you will find a dead bird. On a hot day, the animals can smell the water if there is a way for them to get it they will. Like a big lobster trap they can get in but they can’t get out. Let’s take a look at your tanks!

We have several inspections to choose from:

  • Remote Underwater Video – This is is our most popular and economical inspection. We document all State required inspection points. Our report is delivered in a notebook with photographs of inspection points and an underwater video that covers the interior roof, water surface, waterline and underwater areas visible from our remote underwater camera and lighting system.
  • Remotely Operated Vehicle (ROV)- Covers everything above with additional underwater video taken from one of our ROV’s. This allows you to get a more detailed inspection for much larger facilities. It also allows a customer to get great documentation on specific areas if needed.
  • Diver Inspection– Our potable water dive crew is usually reserved to clean water storage tanks and towers. The divers are sealed in their own environment using a DRY SUIT. No part of the divers body touches the water in addition, to meet state and federal requirements divers are washed down with a 200ppm chlorine solution. Divers are able to get an even more detailed inspection.
  • Tank Cleaning and Inspection– All of our inspections include an underwater video of tank floors. This allows us to get a good estimate of accumulated sediment. It is important to know how much sediment is in the tank. Sediment on the floor of the tank that can be a safe habitat for bacteria, protozoa and even viruses. Our cleaning service removes all loose sediment. After the sediment is removed we are able to see the floor of the tank allowing us to document the condition of the paint and see corroded areas if any. When is the last time your tanks were cleaned?

If you are task with inspecting your own tank we can help with that too. I teach a course at the Environmental Training Institute (ETI) located at the UT Arlington Division for Enterprise Development. The class is 16 hours over two days and has class dates scheduled in 2021 and 2022.

E. coli has been found in many drinking water systems, but what is it?

Escherichia coli, commonly referred to as E. coli, is in a group of organisms known as coliforms: 
common bacteria found in the digestive system of humans and animals.

There are only a few strains that cause serious disease in humans. One of these strains is responsible for causing Traveler’s diarrhea, and the second is E. coli O157:H7, which contaminates meat and leafy vegetables. 

Under a high magnification of 6836X, this digitally-colorized, scanning electron microscopic (SEM) image depicted a growing cluster of Gram-negative, rod-shaped, Escherichia coli bacteria, of the strain O157:H7, which is a pathogenic strain of E. coli.
Source: CDC/ National Escherichia, Shigella, Vibrio Reference Unit at CDC – Photo Credit; Janice Haney Carr 2006.

The “O157:H7” strain has caused serious hemorrhagic diarrhea and for some, long-term complications resulting in illness and even death in some cases.


The presence of E. coli is used as an indicator to monitor the possible presence of other more harmful microbes, such as Giardia, Shigella, Norovirus and the Protozoa Cryptosporidium. Diseases resulting from contact with water contaminated by E. coli can cause gastrointestinal illness, skin, ear, respiratory, eye, neurologic, and wound infections. The most commonly reported symptoms are diarrhea, stomach cramps, nausea, vomiting, and low-grade fever. When E. coli exceeds the permissible level in recreational water, it results in the closing of public swimming pools and fishing areas.

Some possible sources of fecal contamination include wildlife, agricultural runoff, or runoff from areas contaminated with livestock manure, wastewater treatment plants, or private septic systems. Heavy rain may cause organisms to be washed into waterways, lakes, or groundwater. If contaminated water is then used as a source of drinking water and is not treated, or is inadequately treated, it may result in illness.

When this contaminant makes its way into a drinking water system sediment found on the bottom of water storage tanks can provide a safe habitat. E. coli along with other bacteria and pathogens, can find shelter from disinfectants under the soft sediment that accumulates in storage tanks.

The  Centers for Disease Control and Prevention list E. coli as one of the top 10 Causes of outbreaks in public water systems.

The best way to insure that E. coli or other bacteria will not invade your tank sediment is to remove it. Clean your water storage tanks then maintain them by getting them on a cleaning schedule.

Since 1997 Ron Perrin Water Technologies, Inc. has been a leader in the inspection and cleaning of water storage tanks and towers. Our inspection methods cover all state required inspection points. We also include a video produced by a underwater camera and lighting system that are able to properly inspect the interior floors of your facilities to determine sediment levels. We do all of this with no disruption in service and no water loss.

Our potable water dive team can keep your tanks clean with no disruption in service and minimal water loss. When sediment is removed the habitat that allows bacteria and other contaminants to remain in your tank is also gone. This allows the disinfectants like chlorine to do a much more effective job. Our customers report to us that they use less chlorine, after their tanks are cleaned to meet standards.

E. coli – CDC –Escherichia coli (abbreviated as E. coli) are bacteria found in the environment, foods, and intestines of people and animals. E. coli are a large and diverse group of bacteria. Although most strains of E. coli are harmless, others can make you sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections, respiratory illness and pneumonia, and other illnesses.
