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.
