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.
