Fire Suppression Tank Inspection and Cleaning – NFPA 25

NFPA 25 – Fire Suppression Tank Inspection and Cleaning.

NFPA code 25 is the requirement under the National Fire Prevention Association for fire protection tanks to be inspected at least once every five years.

Insurance coverage is often based on compliance of NFPA codes and standards. Our inspections allow you to meet NFPA 25 requirements without draining your water storage tanks or towers.  You never need to lose your fire protection with our inspection service – you are always ready for an effective response in a fire emergency.

We have three tank inspection methods depending on your needs:

Remote underwater video camera

Remotely Operated Vehicle (ROV)

Diver inspection and cleaning service

Water Tank Inspection – Shopping for a Potable Water Tank Inspector? Think about This-

Here are a few things to consider when shopping for a contractor to perform work in a potable water storage tank.

  1. Look for a specialist
  2. Check photos on their web site
  3. Check references
  4. Require an insurance certificate
  5. Proper training for employees performing work

Specialist: We live in an age of specialist.  As a rule Specialist know their topic inside and out.  When contracting a company to enter your potable water system it is better to deal with a contractor who is focused on entering potable water systems.  Companies who do nothing but service potable water systems are more likely to have equipment only used in potable water system.  Specialist in potable water work are also more likely to have disinfection procedures and a disinfection solution that meets AWWA standards.  When it is your business to do it you are just more likely to do it right.

Photos: No matter what you see on advertisements, or told on the phone, a quick check of a companie’s web site can quickly show you what their focus is on.  Many diving contractors are simply focused on Diving.  Potable water diving may just be one of the things on their long list of things they do to make money diving.  If the photos on their web sight show diving in lakes, rivers, and streams you need to trust them to somehow clean their equipment enough to enter your water system.  Like they say, a photo is worth a million words. Some contractors say they have reserved equipment they only use in potable water.  However, the photos on their own web site may show they actually use the same gear to do all diving services.  If you can find a company that specializes in potable water diving, the photos on their web site should confirm that claim, not dispute it.

References:  If a company has been working for more than a week or two, they should have references.  Ask for a list of customers that you may be allowed to contact.  Another way to check references is by looking at their company Facebook page, or the owner’s linked-in page.

Insurance:  Ask for a certificate of insurance sent from the companies insurance agent. Do not accept a certificate sent directly from the contractor. It is just too easy to change dates or fabricate the certificate from scratch.  Make sure the contractor has Liability, workers comp and commercial auto.  While they are all important, the workers comp may be the most difficult and expensive for the contractor to acquire.  Climbing and diving into potable water storage tanks and towers is “high risk contracting” by any measure.  If an accident occurs, and the contractor is not covered by his own workers compensation insurance, the customer will be liable for the injured employee.

Training:  High risk contracting may only be done safely if the contractor has required before employment, or taken the time to send each and every employee on the job site proper training.  The majority, if not all diving contractors, require that divers have diving certifications before employment is offered.  Beyond dive training, employees should also have documentation showing they have had both Confined Space and Fall Protection training.

The Importance of a Water Tank Inspection

I write a lot about inspecting and cleaning water storage tanks.  My focus is on tanks that store potable water, or more simply, municipal drinking water.  To understand why this is so important you need to understand how water systems work.  The water we drink comes from lakes, rivers, streams or water wells and is also known as ground water.

It is then processed at a water treatment plant, smaller. Systems on well water may simply inject chlorine into the water as it goes into a storage tank.  The larger systems that most of us are on filter and process the water to perfection then send it out into the distribution system where it waits in water storage tanks and towers until it is needed.

The water storage tanks and towers serve two critical functions, they allow enough water to be at the ready so it is always available to us, the end user; it provides enough water pressure to not only get it to your tap, but also keep it safe.  The positive water pressure insures that contaminants will not enter the system.  If there is a line break the system will lose water, the break or leak also allows contaminants to be sucked in.

Any time pressure can not be maintained for any reason the system is at risk and will issue a boil water advisory or order to protect public health. The water storage tanks and towers you see around town are the last stop water makes before being served at your tap.  Water storage tanks on the ground are known as Ground Storage Tanks or GSTs, Water Towers are referred to as Elevated Storage Tanks or ESTs. These facilities have a life span of 30 to over 100 years if properly maintained.

Over time sediment builds up on the floor of GST, and EST, storage facilities. One particle at a time over several years and sometimes over several decades, sediment levels can continue to grow.  The soft sediment can become a nutrient rich habitat that according to the USEPA can support bacteria, protozoa and even viruses.  Sediment can also offer a safe harbor from treatment chemicals. As the sediment grows, more and more chemicals are used in an attempt to meet water quality standards set by the USEPA and enforced by state health or environmental agencies.

20180207_111442

This is why an annual inspection of water storage tanks and towers is so important you can not make plans to fix a problem unless you know you have the problem in the first place.

Inspection contractors often use underwater cameras to get a look at the interior conditions of the facility.  This can be done while the facility remains in service and full of water.  If the tank is found to have sediment potable water divers can be contracted to clean the water tank with minimal water loss.  Removing the layer of sediment on the floor along with all contaminants that may be living in it, this quickly restores the facility to the point that much less chlorine is needed to maintain water quality standards.

 

About our company:

Since 1997 Ron Perrin Water Technologies has been a leader in the inspection and cleaning of potable water storage tanks while they remain In-Service. Our company is located near Fort Worth, Texas in the DFW area. We serve Texas and fourteen other states including Oklahoma, Arkansas, Louisiana, New Mexico, Kentucky and Florida. Of course, we inspect more tanks in our home state of Texas than any other state.

We offer three types of underwater in-service tank inspections to better meet your needs: 1) Remote Underwater Camera.  Our underwater remote video camera and lighting system is our most popular and economical inspection method. This allows you to see underwater conditions and get a good look at the floor of the facility.  2) Remotely Operated Vehicle or (ROV).  The ROV water tank inspection is the right choice for larger tanks, the ROV is equipped with motors and is able to swim to the far side of the tank for a better look. 3) Diver Inspection.  Potable Water Divers are dressed out in dry suits and washed down with a chlorine solution to meet AWWA and EPA standards.  The diver is a good choice when you want to get a good look at a specific spot in the tank.  Our most common diver inspection follows our tank cleaning service.  Divers cover the floor of the tank and any problem areas they may see using a high resolution camera and underwater lighting system this is our best inspection and it is free with each tank cleaning.

Missouri has no requirement to clean water towers

Chris Hayes from Fox2 News in St Louis, Missouri recently interviewed me for a story he did about a water tank in Leadwood, Missouri. The tank had been inspected once about 17 years ago and as far as anyone knew, had never been cleaned. Chris was contacted by some residents of the community who had brown water coming out of their taps.

I was happy to contribute both video and comments to this story. Water storage tanks should be inspected yearly for public safety, even if the state they are in has no regulations at all. Mr. Hayes did a great job. He found the larger systems around St. Louis had all been recently inspected. Many smaller systems seem to fall back on regulations to decide what is really important.

Although the state of Missouri has no written regulation or rules on when tanks should be inspected they do say this about the inspection and cleaning of water storage tanks: “...clearly necessary to protect public health.”

You would not drink out of a dirty glass, why do these people have to drink water from a dirty tank?  See the video on our Company Facebook Page:

On the NEWS with i-Team Reporter Ginger Allen

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.  

OLYMPUS DIGITAL CAMERA

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.

Ron Perrin Speaks to I-Team Reporter Ginger Allen

THE EPA MAY SOON REQUIRE ALL WATER STORAGE TANKS AND TOWERS TO BE INSPECTED AND CLEANED

Ron Perrin Owner Ron Perrin Water Technologies

Ron Perrin Owner Ron Perrin Water Technologies

On October 15th 2014 the EPA held a meeting to decide if there should be a rule to require water storage tanks and towers to be cleaned and inspected.

The webinar is over but the EPA is still taking comments until the end of 2014.  If you would like to make a comment on this issue, please send an e-mail to:  SFIWebinar@cadmusgroup.com. Or take the poll below and I will send in the results at the end of the year.  This is a chance to let your opinion be known!

My customers tell me they need less chlorine to meet water quality standards after I remove the sediment from water storage thanks and towers.  Sediment enters the tank one particle at a time and eventually accumulates enough for bacteria, protozoa and even viruses to use it as a habitat, grow and become a serious health

problem.  If proper inspections are not done to determine sediment levels, corrective action is seldom, if ever, taken.  My opinion is that potable water storage facilities should be inspected inside and out every year, and a cleaning program to assure tanks and towers are cleaned every 3 to 5 years should be in place on all tanks.  What do you think?

Now we can add a brain-eating amoeba to the list of contaminants that can be in tank sediment

Sediment being removed from the floor of a potable water storage tank by a dive crew.

Removing sediment from the floor of your water tanks and towers may also be removing the habitat that allows bacteria, protozoa and viruses from getting a foothold in your distribution system.   Now we can add a brain-eating amoeba to the list of contaminants that the sediment on the floor of your water storage tank can support.

September 16, 2013, NBC News reported: “Deadly brain amoeba infects US tap water for the first time”. The death of a 4-year-old boy near Violet, LA., was linked to the Naegleria fowleri amoeba. The child had been playing on a backyard slip-n-slide that used water from the St. Bernard Parish water system, that was later found to be contaminated with the amoeba. “Tests show it’s present throughout the water supply system in St. Bernard Parish, directly southeast of New Orleans.”

According to the CDC:  “Naegleria fowleri (commonly referred to as the “brain-eating amoeba” or “brain-eating ameba”), is a free-living microscopic ameba, (single-celled living organism). It can cause a rare and devastating infection of the brain called primary amebic meningoencephalitis (PAM). The ameba is commonly found in warm freshwater (e.g. lakes, rivers, and hot springs) and soil. Naegleria fowleri usually infects people when contaminated water enters the body through the nose. Once the ameba enters the nose, it travels to the brain where it causes PAM, which is usually fatal. Infection typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. In very rare instances,Naegleria infections may also occur when contaminated water from other sources (such as inadequately chlorinated swimming pool water or heated and contaminated tap water) enters the nose. You cannot get infected from drinking water contaminated with Naegleria.”

The CDC also tested nearby DeSoto Parish Waterworks Dist. #1 because it was the near the site of an infection that happened in 2011 from non-potable water (lake or river, etc.). On October 8, 2013, The CDC confirmed the presence of the rare amoeba in five locations in DeSoto Parish Waterworks Dist. #1.

Click Here to see the map:  NUMBER OF CASE-REPORTS OF PRIMARY AMEBIC MENINGOENCEPHALITIS CAUSED BY NAEGLERIA FOWLERI

Heat is also a factor, an increase in only ten degrees can double the speed of bacteria growth. As record high temperatures become more common in summer months we see that keeping water distribution tanks free of sediment build up may be more important than ever before. Removing the sediment from your water tank may prevent a disaster before it can ever start.

We offer potable water tank inspections and cleaning.

Potable Water Diver

Potable Water Diver

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.

Assessment and Corrective Action required under 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.

Deadly amoeba found in a U.S. drinking water system

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.

For more see: “Four year old’s Death linked to Rare Amoeba in Water System”

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.

Why We Clean Tanks.

Top 10 Causes of Contamination Outbreaks in Public Water Systems according to the Center for Disease Control (CDC).

  • Giardia
  • Legionella
  • Norovirus
  • Shigella
  • Campylobacter
  • Copper
  • Salmonella
  • Hepatitis
  • Cryptosporidium
  • E. coli, excess fluoride (tie)

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. Keep your tanks clean with potable water diving services from Ron Perrin Water Technologies call 817-377-4899.

Out-of-sight and out-of-mind, sediment in a water storage tank can hide a wide range of contaminants. Keeping the tanks clean will help you maintain a safe water system and meet water quality standards.  Take a quick look at what we keep out of your water storage tank by removing accumulated sediment. All potable water storage tanks should be on a cleaning schedule, is yours?  You do not want to drink these guys!

WATER TANK INSPECTION – WATER TANK CLEANING

https://potabletankdiver.wordpress.com AKA: http://www.tankdiver.us is the blog for Ron Perrin Water Technologies.  Since 1997 we have been a leader in water tank Inspection and water tank cleaning.  

We offer 3 different ways to inspect your WATER STORAGE TANKS and towers.

  1. Remote camera inspection.  Our most economical and popular method. we lower a camera into your Potable Water Tanks to get a look at underwater conditions including sediment levels while the tank remains in-service.
  2. Remotely operated vehicle or ROV inspection is our second method.  The ROV is motorized allowing it to swim to the rear of the tank.  This method is recommended for larger facilities.
  3. Diver inspection.  Potable Water Divers are sealed in their own environment, then washed down with a 200ppm chlorine solution.  This allows the diver to enter the water system and move around as needed to inspect, clean or make repairs.
