I just came across this video on my computer and thought I would post it again. Our potable water dive team usually deploys to clean water storage tanks and towers. Occasionally we have a customer who wants a diver inspection. Diver inspection offers more detail than a remote underwater video camera or a Remotely Operated Video (ROV) inspection. The diver can look at specific areas and has the ability to evaluate more if not all of the tank. All of our equipment is purchased for and only used in potable water. We start off by spraying the diver down with a 200ppm chlorine solution just before he enters the tank. Take a look at this quick video and let us know what you think.
Thanks for taking a look at our video.
Since 1997 Ron Perrin Water Technologies, Inc. has been inspecting and cleaning water storage tanks and towers and we all love what we do.
Every time we clean the sediment out of a potable water storage tank we improve the water quality for that community

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.
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.

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.
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 firstname.lastname@example.org.
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.
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.
Sep 26, 2020 Texas residents warned of tap water tainted with brain-eating microbe. Texas officials have warned residents of some communities near Houston to stop using tap water because it might be tainted with a deadly brain-eating microbe.
The Guardian Reported:
The Texas Commission on Environmental Quality (TCEQ) warned the Brazosport Water Authority late on Friday of the potential contamination of its water supply by Naegleria fowleri.
The commission issued an advisory warning people not to use tap water for any reason except to flush toilets in Lake Jackson, Freeport, Angleton, Brazoria, Richwood, Oyster Creek, Clute and Rosenberg.
Those communities are home to about 120,000 people. Also affected are the Dow Chemical works in Freeport, which has 4,200 employees, and the Clemens and Wayne Scott state prison units, which have 2,345 inmates and 655 employees.
The advisory will remain in place until the Brazosport authority’s water system has been thoroughly flushed and tests on water samples show the system’s water is safe to use. It said in a statement that it was unclear how long it would be before the tap water was safe.

With everything going on last year I missed this story. My take on this story is one of the reasons I got into diving water tanks in the first place. To explain why this story made me think about how I came to build a company that puts divers into water storage tanks I need to tell you something about myself and even about my parents.
In the early 1990s I was working as a Texas police officer, and my passion was SCUBA Diving. My love of SCUBA Diving goes back even farther. My dad was Charles B. Perrin, he passed in 2016 at the age of 78. He claims to have purchased the first Aqua-Lung in Fort Worth in the mid 1950’s. He had to order it from a welding supply long before the first SCUBA store opened in Texas. Both my mom and dad spent time water-skiing and SCUBA diving on Possum Kingdom Lake (PK) west of Fort Worth on the Brazos River. They were both civil servants: my dad worked for the IRS and my Mom was an Executive for the Corps of Engineers. Raising their family in the 60’s-80″s this solid middle class income gave them enough extra money to not only afford to give us a great middle class lifestyle, it also allowed them to purchase a second home, something that seems out of reach for most of us today.
They purchased a lake house on Possum Kingdom Lake (PK) where I spent most of the weekends of my youth. Even before they purchased the first lake property my dad had taken me out to PK in a small fishing boat with his one set of Scuba Gear and instructed me how to SCUBA dive. In 1971, I was 12 years old. The Professional Association of Diving Instructors (PADI) was not even founded until 1966. My dad predated standard training practices that would come along after his diving years were done. With no formal courses available my parents taught themselves how to dive with the help of “The Skin Diver” (later renamed Skin Diver Magazine). Sea Hunt starring Lloyd Bridges*, was also a favorite TV program in our home. I personally would not get formally trained and certified until the early 1980’s.
I can still remember my first dive. I was so excited. It was a clear summer day and our 14′ “Little Dude” fiberglass fishing boat was anchored in a remote area over crystal clear water about 10′ deep. I put dad’s tank, mask and fins on just like Lloyd Bridges. I checked the regulator which gave me that great scuba diving sound as cold compressed air shot into my mouth from the 72 cubic inch steel tank strapped to my back. I sat on the side of the boat and dad explained to me how to make entry by going over backwards.
“Hold on to your mask,” he said as he pushed me over the side. The water was cold on my hot sun soaked skin, my heart rate shot up and I was breathing was as rapid as I could breath! I was sure I was going to die as I tried to get my head above water. Turning myself around underwater I shot back to the surface with all my strength but I was stopped by my dad putting his hand on my head and holding me underwater until my breathing finally slowed down and my initial panic subsided. My dad was the worst SCUBA instructor ever! Despite that first dive experience that could best be described as violent or even brutal, I fell in love with diving. By the time I was 14 I was exploring the lake on my own spearfishing in the many coves and inlets. I never had a buddy to dive with but I always had a sharp knife in case I got tanged in an abandoned trout line that seemed to be everywhere I wanted to dive.
Growing up on the lake the brain-eating ameba Naegleria fowleri is something I have been aware of most of my life at least as far back as I can remember. Diving and Water Skiing were my favorite things to do on the lake. In late summer the river flow would slow down. The water going through the dam would be reduced and water become more stagnant. At the same time the hot summer sun warms the water. Naegleria fowleri loves warm water and in late summer Texas lake water gets very warm. I remember news stories from water skiers (usually teenaged children) getting the organism in their nose and dying from it, going back to my teenage years. When the lake level went down too low we stopped diving and water skiing.
When cooler weather arrives in mid September, Naegleria fowlerilies dormant in the sediment at the bottom of lakes and riverbeds, which is why experts advise that you not stir up any more of that sludge/sediment than necessary. First discovered in 1899, Naegleria fowleri is a protist pathogen, known to infect the central nervous system and produce primary amoebic meningoencephalitis.
In 1991 I discovered that the American Water Works Association had a standard to put scuba divers into drinking water. Using a drysuit and a full face mask, a diver could be totally isolated from the water supply. To meet the standard that has been adopted by the USEPA and TCEQ the diver must also be washed down with a 200ppm chlorine solution. Taking the tank out of service and then decontaminating the entire facility with very expensive and time consuming super chlorination procedure. Decontamination of the diver is much more economical. In addition other advantages are the diver can move around all underwater areas. Equipped with a good underwater lighting and camera system the diver can document the condition of the facility and deliver a great inspection report with no water loss or disruption in service. After I mastered diving in potable water I saw a common problem potable water tanks have – over time, sediment collects on the floor of tanks.
I read everything I could about tank sediment. In 1990 the National Drinking Water Advisory Council stated that drinking water contamination from bacteria, protozoa and viruses may be the biggest challenge for drinking water professionals in the future. The future is here, over time almost all tanks collect sediment. Tank sediment can be a safe habitat for a wide host of microbes including crypto andNaegleria fowleri.
When I ask about sediment removal I was told the standard method was a bucket and a shovel. We immediately started working on a better way. First using some methods developed for moving sand to look for treasure off-shore a much simpler method was developed by 1999. We now use a 3″ trash pump to clean most ground storage tanks and with water towers we simply use gravity to create all the suction we need to quickly remove sediment from the floor of the tank. Cleaning water storage tanks is not as common as you may think. Our company inspects over seven hundred tanks a year. Every week we find tanks that have never been cleaned. Currently there are no USEPA rules on when tanks should be cleaned. Texas has administrative rules under 290.46 requiring all potable water storage to be inspected annually. However, Texas along with most other states, have no rules on how often water storage tanks should be cleaned. The interior of water tanks often remain, “Out-of-sight and out-of-mind”.
KEEPING WATER STORAGE TANKS CLEAN IS IMPORTANT
This story is about communities on the lower part of the Brazos River that have hadNaegleria fowleriturn up in their drinking water system. The standard remediation for this is often to perform a chlorine burn that increases the chlorine to a high level. This kills all contaminants it comes into contact with. So everything on the surface in the water system that is underwater, including all tanks and water mains is sanitized. But what about the contaminants that remain hidden under a layer of sediment in the water storage tank? Administrators often are unaware of any tank sediment that may still be lurking in water storage tanks again, Out-of-sight and out-of- mind. The chlorine burn will kill all contaminants on the surface of the sediment. This is why proper tank inspections that can determine the actual sediment levels are so important. One half to three inches of sediment is very common. Without removing the sediment, contaminants remain in the tank and will continue to be a problem in the future. All water storage tanks should be on a cleaning schedule. Some tanks may need to be cleaned annually while others may be able to be on a three or five year program.
First established in 1997, Ron Perrin Water Technologies, Inc. has been a leader in the underwater inspection and cleaning of water storage tanks and towers. We offer three different inspection methods: 1) remote camera, 2) Remotely operated vehicle (ROV) and 3) Potable Water Diver. Our divers are commercially trained from great schools like The Ocean Corporation where I serve on the Educational Advisory Board. We offer diver cleaning with no disruption in service and minimal water loss on ground and elevated tanks. For standpipes over 70 feet tall we have a Robot Cleaning 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 tank and tower cleaning rates are affordable and we have special pricing for tiny tanks under 10,000 gallons.
Check out our new video series on YouTube. Tap-Talk explores our water distribution systems as we take you along and let you see what we see as we inspect and clean municipal water storage tanks. Our cameras let you see what is inside, we never reveal the utility we are working for or our exact location unless our customer gives us permission. Episode #1 is posted below, less than six minutes, I explain what we do and how we do it, talk about my background and what led me to start my company in 1997.
There is a serious danger lurking in many water systems. Join me, along with microbiologists and a former EPA drinking water chief as they discuss the problem. If you like this video please give us a thumbs up and SHARE it! It is important that water utility managers understand the importance of keeping water storage tanks clean. PLEASE SHARE!

Want More? This video is a 15 minute look back at some of the jobs we have done over the past three years.
Since 1997 we have been inspecting and cleaning potable water storage tanks and towers. Our crews take hundreds and often over a thousand photos a week. Of course, most are a little on the boring side documenting the inspection points of water tanks and towers. Occasionally we turn the cameras on ourselves as we do the work and those are the photos I use to promote our service.
Every time I see this photo I think about how it nails down what we do. I think it was the best of 2020. It is one of our divers cleaning a GST potable water storage facility. The tanks are always a lot cleaner when we are done, about half way through you can see a lot of sediment on the floor and less that perfectly clear water, it is a real working photo, not something produced in perfect pool water conditions.
Here are some other photos I found to be impressive in 2020 I hope you like them too.
