On October 15th 2014, the EPA held a public meeting in regards to Distribution System Storage Facility Inspection and Cleaning. I attended that meeting in person to express my opinion on this issue. During the meeting a couple of surprising things were revealed. Many were under the impression that water tanks and towers were already being inspected during Sanitary Surveys performed by state regulators, when in fact most, if not all, state agencies do not allow their employees to climb to the top of water tanks and towers.  The few states that climbed the towers in the past did not do an internal inspection of the facility.


A survey had been sent to state regulators to get their opinion on this issue. About half thought a regulation would be a good idea, the other half thought a paper on guidance would be sufficient. I went away from the meeting more convinced than ever that there should be a national regulation requiring all potable water storage tanks to be inspected and cleaned on a regular schedule.


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 their water storage tanks 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 to 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 ensure tanks and towers are cleaned every 3 to 5 years should be in place on all tanks.

Topic: Distribution System Storage Facility Inspection and Cleaning

Background: The United States Environmental Protection Agency (EPA) Office of Ground Water and Drinking Water announces a public meeting and webinar on distribution system storage facility inspection and cleaning. The purpose of the meeting and webinar is to gather input and information from the public and stakeholders on the appropriate frequency of distribution system water storage facility inspection and cleaning, current practices, and the risk management approaches that can be taken to assure that inspection, cleaning and corrective action occur as necessary to help maintain facility integrity and finished water quality. The presenters and panelists will provide background information concerning storage facility inspection and cleaning, existing state programs and available guidance documents. For additional background information, please refer to the Federal Register notice published on Thursday, September 4, 2014 (79 FR 52647).

Public Comments: This meeting is open to the public. EPA encourages public input and will allocate time on the agenda for public comment. To ensure adequate time for public involvement, individuals or organizations interested in making a statement should mention their interest when they register. All presentation materials and statements should be emailed to SFIWebinar@cadmusgroup.com by October 8, 2014, so that the information can be incorporated into the webinar as appropriate. Only one person should present a statement on behalf of a group or organization, and statements will be limited to five minutes. Availability to make public comments will be provided on a first-come, first-served basis in the time available. Additional comments from attendees who did not pre-register to make comments will be taken if time permits. Comments, written statements, data or information can also be sent to SFIWebinar@cadmusgroup.com after the public meeting and webinar.

 

  1. Background

In the Federal Register notice for the proposed Revisions to the Total Coliform Rule (75 FR

40926, July 14, 2010), the EPA requested comment on the value and cost of periodic distribution

system storage tank inspection and cleaning. The EPA received comments regarding unsanitary

conditions and contamination that can be found in storage facilities, which are not routinely

inspected and cleaned, including breaches and accumulation of sediment, animals, insects and

other contaminants. Some commenters suggested the need for a Federal regulation requiring

systematic inspection and cleaning because the existing practices are not successful in all cases.

Others suggested that regular sanitary surveys conducted by States and the adherence to existing

industry guidance could resolve such issues. The comments can be reviewed in the docket for the

rule at http://www.regulations.gov/#!documentDetail;D=EPA-HQ-OW-2008-0878-0283. This

meeting and webinar and the subsequent opportunity to submit comments are intended to collect

more data and information about the frequency of distribution system water storage facility

BILLING CODE 6560-50-P

Revised Total Coliform Rule (RTCR) Requires Assessment and Corrective Action when there are indications of coliform contamination.

On February 13, 2013, EPA published in the Federal Register Vol.78 No.30 (part III)  the revisions to the 1989 TCR.  EPA anticipates greater public health protection under the Revised Total Coliform Rule (RTCR) requirements.  These new requirements will go into full effect April 1, 2016.

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. This final rule also updates provisions in other rules that reference analytical methods and other requirements in the 1989 TCR, like public notification and ground water rules.

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 can build up on the floor area of almost all water storage tanks and towers.  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.

What is it?  It’s a video about how sediment builds up in our public drinking water supplies.  It should help you understand the importance of having your potable water storage tanks inspected and cleaned.

Out of sight and out of mind.  The cleaning of water storage tanks remains one of the most overlooked health concerns today.  I have been showing this video to every person I can for years.  I just can’t get to enough water utility managers, water board members, mayors and city council people to make a difference.  Information is power, the right people just don’t have the right information to make the right decisions.  Everyone is cutting back and it is easy to cut back on a maintenance budget.  Tell the water utility manager to do the inspections himself.  So, year after year the water tank is inspected without seeing the inside floor of the tank.  Because an inspection contractor with an underwater camera was not in the budget.  So the sediment goes unseen and unnoticed year after year.  Inspections and cleanings would only be one or two percent of the budget.  But the money never gets allocated because the people in control do not understand the importance of it. As the economy gets worse, fewer tanks will be inspected and cleaned while more and more people will return to drinking tap water.

I need your help.

We have all seen the silly or funny “viral videos” that make their way around the world.  This one deserves to be shared so that more people who have influence on the way water systems are managed will understand the problem.  Tanks need to be inspected. If they are dirty, they should be cleaned. It is a very simple message and one that I have spent everything I have made in since 1997 trying to get across to water managers. Please share this video with your friends and encourage them to pass it on to their water utility, city council person, or water board.  Managers just don’t know what is going on inside their water storage tanks.  Having them inspected by a professional with underwater camera equipment will let them know if they have a sediment problem.  If they have sediment, removing it is a cost-effective way of maintaining the public health of that water system.

If you don’t know about Current TV, it is a cable channel and web site that is viewer created. If your video gets enough votes they put it on TV.  My mission is to show as many people as I can the health concerns of sediment in Public Water Supply storage tanks.  This would be a great way to get my message to thousands of people at a time.  Click on my link below and VOTE me “UP!” on the right side of the page!  By helping to spread this message YOU ARE MAKING A DIFFERENCE!    Thanks for your help!

This web site is about spreading this message and educating people about the importance of inspecting and cleaning their water potable storage tanks.

Thanks for your help,
