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.

Out of Sight, Out of Mind: What’s in Your Water?

Out of Sight, Out of Mind: What’s in Your Water?  is a documentary where microbiologists and tank inspection professionals discuss the importance of having potable water storage tanks inspected and cleaned regularly. Currently the Environmental Protection Agency (EPA) has no regulations that require potable water storage tanks to be cleaned. We are hoping to raise awareness of this issue in order to change that.

We have been working on this project for over two years and it it time to raise some cash to finish it up.  I hope you will be a part of this, please click here and find out how you can help!  https://igg.me/at/whatsinyourwater/x/11623864

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

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?

We offer potable water tank inspections and cleaning.

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.
