EARTH DAY 2020

Today is Earth Day.  Every year on April 22, trees are planted, litter is cleaned up, and awareness for the issues plaguing the planet are raised, in honor of the holiday, which is celebrating its 50th anniversary in 2020.  The first Earth Day was on April 22, 1970. Environmentalists took to the streets with concerned citizens and pop culture icons, like poet Allen Ginsberg, who were asked to speak on behalf of Mother Earth.

The 1970s saw the passage of the most comprehensive environmental legislation in U.S. history, including the Clean Air Act, the Water Quality Improvement Act, the Endangered Species Act, the Toxic Substances Control Act, and the Surface Mining Control and Reclamation Act. In addition, just eight months after the first Earth Day, Richard Nixon approved the creation of a new organization tasked with monitoring the nation’s natural assets: the Environmental Protection Agency. You can find more facts about earth day at DO Something . ORG.

 I manage a company that spends every day inspecting and cleaning water storage tanks and towers.  Our goal is to save treated drinking water by performing required inspections without draining storage tanks.  We use underwater cameras that allow us to enter the water system, inspect the tank, and produce a comprehensive report on its condition without disrupting water service.  Over the years our “no water loss” inspections have saved tens of millions of gallons of treated drinking water.

Earth Day makes me think about what could be and how we could do more. In 2019 we inspected 651 potable water storage tanks and towers, but we only cleaned 105 of them. and that is a very typical year.  Even on one of our best years in 2017 we inspected 863 facilities but only cleaned 95.   There were hundreds more that needed to be cleaned but the decision was made not to clean the tank.

To understand why we only clean a fraction of the tanks that need to be cleaned and why that is a big deal, I need to give you a brief explanation of how water systems work.  Your drinking water comes from ground water (aquifers), or from rivers and lakes (surface water).  The most common disinfectant used is chlorine if it is from surface water it is also processed through different media at a water treatment plant.  After the water has been processed it is pumped into a storage facility like a ground storage tank tank (GST), or an elevated storage tank (EST), where it sits and waits until you use it at your tap (60 Second Video Click here).

A few states have rules that require water storage facilities to be inspected every year but very few require tanks to be cleaned. Texas Administrative Code 290.46 (M)(1) requires all potable water tanks to be inspected inside and out annually.  I guess it was assumed that when the inspection showed the interior floor was covered with sediment the utility would take action to keep it clean.  That is not what is happening.  Water regulations that keep us safe are much too complex for this article. The short answer is, as long as water testing is negative for coliform the water is deemed to be safe.  Coliform is what is looked for to determine if microbes can live in the water.  When it is not found the water is deemed safe to drink.  About 7 years ago new rules under the  Revised Total Coliform Rule (RTCR) required some additional monitoring of total coliform’s and E. coli.

There are now also requirements for assessments and corrective action when monitoring results show that public water systems (PWS) may be vulnerable to contamination.

In this case if no other breach can be found a good look at the water storage tank would meet the requirements for an additional assessment.  If the results of the inspection showed that sediment was covering the floor of the tank, cleaning the tank could be the corrective action needed. Unfortunately, the complexity of the Revised Total Coliform Rule does not result in most tanks not being cleaned.  In Texas, tank inspections are required but tank cleaning is often put off due to budget constraints or because those responsible don’t understand the dangers that can lurk in sediment.

The problem is as simple as a game of Hide & Seek.  When conducting the required water testing a sample of water is taken from a tap on, or near, the water tank.  Coliform must be found in the water to know there is a problem.  Only a few feet away sediment on the floor of the tank may be hiding the contamination.  A host of undetected microbes including bacteria, protozoa and even viruses, can use the tank sediment to get a foothold in the tank. Often left undisturbed for years, these contaminants continue to grow until they overpower the disinfectant in the tank.  They can then be detected through required water monitoring but the damage is already done.  The water system is compromised when testing finds too much Coliform in the system. Then boiled water notices are sent out to protect public health.

IMG_20200422_125907

Sediment covering the floor of water storage tanks is a breach.  It is as bad as a hole in the roof.  Sediment can let almost any microbe or parasite that may have just passed through get a foothold in the water system, grow and become a public health problem.

Tank inspections are required in some states. However, even in those states tank cleanings still require a sales pitch unless the water system is compromised and testing finds too much Coliform in the system.  That is often when we get the call.

Many well managed and well funded water utilities keep their water tanks and towers cleaned.  This is why I came up with the tag line “Your zip code should not determine your water quality”.  The fact is, like many other things in life, where you live affects almost everything, but it should not affect your water quality in the United States. Smaller systems that are not well-funded just need additional information about why keeping water tanks clean makes such a big difference.  When tanks are clean the cost of disinfectants like chlorine goes down. The system is healthier and less likely to get a RTCR violation.  In this case doing the right thing actually saves money and makes maintaining regulations easier.

This small, overlooked part of the world affects millions of people.  Keeping tanks clean is just basic housekeeping and should be the standard at every public water utility.  Unfortunately, it is not the first thing thought of when violations occur.  The knee-jerk reaction is to add more disinfectants. However, when the maximum residual is reached, the decision is often made to change disinfectants.  This just adds up to more time and money wasted if the tanks have not been properly inspected or kept clean.  

Thanks for staying with me this far.  This is where I decided to DO SOMETHING.

The Ron Perrin Clean Water Tank Project Inc. was established to educate water utility managers about the importance of keeping tanks clean.  Help me get water utility managers to think about cleaning storage tanks FIRST instead of Last or not at all! We are producing a documentary, promoting our blog and creating literature on the importance of keeping tanks clean. Our non-profit is registered and can be supported through the SMILE program at AmazonSmile.  Search for the “Ron Perrin Clean Water Tank Project Inc.” and you can round up the change on your Amazon Purchase to allow us to get the change and help us DO SOMETHING that needs doing.  Together we can make a change by improving water quality for more people.

Do you still need a reason to clean your water storage tanks

Sediment on the floor of your water storage tank is a Breach in your system. The more sediment you have in your water storage tanks the bigger your risk for having a water-related contaminant issue. Tank sediment builds up over time and can provide a wide range of contaminants including viruses a way to get a foothold in your water system. The tank sediment can provide a safe habitat allowing a small number of bacteria or viruses to quickly grow into the billions.

The Centers for Disease Control and Prevention recently released a guidance and fact sheet on transmission of the novel coronavirus in water.

THE GOOD: The agency stated: “Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19.”

THE BAD: The fact is other viruses are found in drinking water, in fact you will find them in the top ten contaminants. Including Hepatitis A, a vaccine-preventable, communicable disease of the liver caused by the hepatitis A virus (HAV), and Norovirus. A very contagious virus that causes vomiting and diarrhea. Conventional water treatment methods should also prevent these viruses from contaminating drinking water systems but they remain in the top ten of drinking water-related contaminants.

Here is the top ten list of Water-related Diseases and Contaminants the CDC found in in Public Water Systems.

The United States has one of the safest public drinking water supplies in the world. Over 286 million Americans get their tap water from a community water system (1). The US Environmental Protection Agency (EPA) regulates drinking water quality in public water systems and sets maximum concentration levels for water chemicals and pollutants.

Sources of drinking water are subject to contamination and require appropriate treatment to remove disease-causing contaminants. Contamination of drinking water supplies can occur in the source water as well as in the distribution system after water treatment has already occurred. There are many sources of water contamination, including naturally occurring chemicals and minerals (for example, arsenic, radon, uranium), local land use practices (fertilizers, pesticides, concentrated feeding operations), manufacturing processes, and sewer overflows or wastewater releases.

The presence of contaminants in water can lead to adverse health effects, including gastrointestinal illness, reproductive problems, and neurological disorders. Infants, young children, pregnant women, the elderly, and people whose immune systems are compromised because of AIDS, chemotherapy, or transplant medications, may be especially susceptible to illness from some contaminants.

Why Isn’t ChlorineTreatment Enough?

I had some water utility workers ask me, “Why isn’t chlorine treatment of potable water enough to keep water safe? Why should we worry about cleaning tanks when we already use chlorine?”

Chlorine works great as long as there is not a breach in the tank. When there is a breach like a hole in the top that lets birds and insects inside the tank, the chlorine can not keep up. This is why annual tank inspections are so important. People have died from this scenario, see: “Salmonella Outbreak in Alamosa, Colorado“. According to USEPA officials a sediment build up on the interior floor of a water storage tank is another type of breach. Bacteria like Legionella, protozoa like Cryptosporidium, and a wide range of viruses including Norovirus can hide and GROW in the tank sediment.

Do you know what the #1 cause of municipal water contamination is? According to the CDC it is a microscopic parasite called Giardia. The sediment becomes a perfect habitat providing both shelter and food for Giardia and many other microorganisms to grow. In time, the contaminants can reach a point where they overwhelm chlorine or any other disinfectant you may be using. Keeping tanks clean keeps your drinking water safe.

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.

Cleaning Water Storage is Important

This Is 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! www.rpwt.us

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.

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.
