Here is a quick video that introduces our 2018 dive crew and potable water inspection team.
November 7th, 2014, Ginger Allen and the CBS 11 i-Team watches as my company inspects and cleans a north Texas water tower. The tower was cleaned as a normal maintenance procedure. A light- brown dusting of sediment was removed from the interior floor before it could get deep enough to support bacteria and become a problem.
The tower was cleaned by a Commercial Diver who was trained at OCEAN CORP, Houston, Texas. The Diver is sealed in his own environment, then washed down with a chlorine solution. Because we specialize in the inspection and cleaning of Potable Water Storage Facilities, all of our equipment is purchased for, and only used in, potable water.
This utility is doing a great job of maintaining their system. However, utility managers across the country struggle to get the funds to properly maintain their systems. The EPA is currently considering a regulation that would require all water storage facilities to be inspected and cleaned at regular intervals. This new requirement could improve the water quality for millions of Americans.
The EPA is taking comments on this proposed regulation until the end of the year. We have the contact information posted on our blog, or you can just take our poll at: www.cleanwatertankproject.com. The poll results will be turned in to the EPA at the end of the year.
Safe tap water is something everyone should have.

This story aired on November 19, 2014 at 10:00 PM. By the end of 2014 it had been shared on Facebook over 400 times! Ok, it is a lot for a story about dirty water towers! Our poll on the next post was shared 118 times when the numbers mysteriously went away. It now shows 0 shares, I am not sure how that happened or why I am telling you about it, I guess I found it interesting or frustrating I’m not sure which…
Thanks for taking the time to check this out.

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. For more information on using a Potable Water Dive Crew to clean your potable water tank or tower see our cleaning page: www.ronperrin.com/cleaning
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.

August 2013, the death of a 4-year-old boy staying near Violet, Louisiana, was linked to the naegleria fowleri amoeba. The child had been playing on a slip and slide connected to the St. Bernard Parish’s water system that was later found to be contaminated with the amoeba.
More common in Australia NBC news reported that this was the first case in the U.S.
Keeping the city’s potable water storage tanks and towers clean may be more important now than ever!
Over time almost all tanks accumulate sediment on the floor. Any amount of sediment can become a habitat for bacteria, protozoa (like Cryptosporidium) and viruses. However, when tests show chlorine depletion, the idea of removing the sediment is usually not thought of. Additional treatment chemicals are usually the first line of defense, quickly becoming chemical warfare and potentially leaving the tank with low, or no, chlorine protection for long periods. American Water Works Association (AWWA) recommends that potable water storage tanks be cleaned every 3 to five years. Few states actually require tanks to be cleaned on a regular basis, and some don’t require it at all.
When a contaminant (bacteria, protozoa or viruses) enters a water storage tank and finds sediment to get a foothold in, chlorine can be quickly depleted while the contaminants grow under the protection of the sediment. Even otherwise harmless bacteria can help to deplete chlorine reserves leaving the tank vulnerable to more dangerous contaminants.
Removing sediment from the floor of potable water storage tanks greatly reduces the chance that any contaminant can get a foothold in the distribution system and grow to become a larger problem.
So why isn’t cleaning potable water storage tanks a common practice? Removing tanks from service to perform cleaning is time consuming and expensive. The smaller the water utility, the more difficult it is to find the budget for preventive maintenance. There are many contractors that offer Potable Water Dive crews that can remove floor sediment with little or no down time and minimal water loss. Using a qualified potable water dive crew to clean water storage tanks can save the water utility time and water.
Keeping potable water storage tanks free of accumulated sediment is essential for the health of the system and the health of your customers. If you administer a drinking water system, make a plan to schedule cleanings and stick to it.

For more information on Naegleria fowleri amoeba in drinking water see:
NOTE: You cannot be infected with Naegleria fowleri by drinking contaminated water. In very rare instances, Naegleria infections may also occur when contaminated water from other sources (such as inadequately chlorinated swimming pool water or contaminated tap water) enters the nose. (For example: when people submerge their heads or cleanse their noses during religious practices, and when people irrigate their sinuses (nose) using contaminated tap water.)
We recently Purchased a DEEP TREKKER ROV to use inspecting potable water storage tanks and towers.
This video shows our first “Test Flight” in a clearwell 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.
