The dates have been announced in the Environmental Training Institute summer catalog.

100_7075-1

The Environmental Training Institute at UT Arlington has developed a 16 hour course designed to help water utility workers properly inspect potable water storage tanks and towers.  This class is also recommended for utility owners and managers who may be assigning or contracting someone to inspect their storage facilities.

The course will cover safety and liability issues such as confined space entry, fall protection and general personal protection equipment that will be needed.  What to look for and how to document your findings will be a center point of the class.  Students

will learn the different types of contaminants that can use tank sediment as a habitat, grow and become a

public health problem.

Many different inspection methods will be covered from taking the tanks completely out of service, to leaving them full of water and using an underwater camera or contracting a commercial diving company to perform the work.

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. What do you think? Take THE POLL BELOW and also visit http://www.tankdiver.us.

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

[FR Doc. 2014-21073 Filed 09/03/2014 at 8:45 am; Publication Date: 09/04/2014]

National Primary Drinking Water Regulations: Finished Water Storage Facility Inspection Requirements Addendum to the Revised Total Coliform Rule.

EPA is planning to propose an addendum to the Revised Total Coliform Rule (RTCR) to strenghten public health protection by including finished water storage facility inspection (SFI) requirements. In the preamble to the July 2010 proposed RTCR (75 FR 40926), EPA requested comment on the value and cost of storage facility inspection and cleaning. (Hide)

EPA received comments regarding unsanitary conditions and contamination that can be found in finished water storage facilities that are not routinely inspected and cleaned, including breaches and accumulation of sediment, animals, insects, and other contaminants. The Agency is developing an SFI proposal in order to allow interested parties to again comment and provide any additional relevant information. EPA is planning to propose and request comment on requirements for public water systems to periodically inspect the interior and exterior of their finished water storage facilities at least and to correct any sanitary defects found. Any potential requirements would apply to all public water systems that have one or more finished water storage facilities. Like the 2013 final RTCR, the proposed storage tank inspection requirements would maintain or improve public health protection by reducing cases of illnesses, and possibly deaths, due to exposure to waterborne pathogens.
          ———————————————————————————————————————-
8/15/14 UPDATE:  At a Water Quality Conference in Austin, Texas earlier this month, I spoke to an EPA official who advised me the inspection requirement of the RTCR will stop short of requiring storage tanks to be inspected.  The rule will be implemented by the States and in full effect by 2015.  We may see a wide range of different interpretations as we compare State to State.
Another EPA spokesperson confirmed to me that a water storage tank inspection would be an important part of assessing the system if there would be a violation under RTCR.  In addition, if sediment was found in the storage tank, cleaning the tank and removing the sediment would be considered a corrective action.  The official refused to go on camera and asked not to be named due to EPA rules against speaking for privately owned companies.
This blog will post new developments on the RTCR as news becomes available.

In November of 2013 the EPA published a report on “The Importance of Water to the U.S. Economy”.

We are in the business of Inspecting and Cleaning potable water storage tanks and towers.  Saving potable water is the center point of our underwater tank inspections and in-service diver cleanings.  In this paper the EPA has drawn attention to how valuable our water supply really is as an essential part of our economy.

This is a must read for anyone who is in the business of water distribution. In fact, by the time you’re done with it you may agree this is a must read for everyone.

This report raises awareness of water’s importance to our national economic welfare.  The report highlights the economic importance of water and at the same time how hard that fact is to measure.   The report establishes some extraordinary facts . For example, “The U.S. Geological Survey (USGS) estimates that in 2005, water withdrawals from groundwater and surface water in the United States totaled approximately 410 billion gallons per day (BGD) (USGS, 2009).1 USGS reports withdrawals for eight water use categories: public supply; domestic self-supply; irrigation; livestock; aquaculture; industrial; mining (including oil and gas extraction); and thermoelectric power. Exhibit 1 shows the distribution of withdrawals in 2005 by category”.

Read the entire report here: “The Importance of Water to the U.S. Economy”.

If you need more information about saving water with underwater tank inspections or in-service diver cleanings for your potable water or fire prevention tanks, click “RON PERRIN WATER TECHNOLOGIES“, or call toll free: 888-481-1768.

Please share this post, or at least the link to:  “The Importance of Water to the U.S. Economy”.  The truth is that the EPA is very good at writing papers, but not so good at getting them read. This is a significantly important work that should become a sounding board for the entire country.

A countless number of biological contaminants can use the sediment in the floor of water tanks and towers to get a foot hold in a municipal drinking water system and grow into a real health concern.  Why should we care what is on the bottom of a water storage tank?

We drink off the bottom of water storage tanks!  Of course like many things the adverse health effects are unequally distributed to poor communities where drinking store bought bottled water is not a given, It is also these communities who have underfunded water systems that suffer from lack of maintenance.

Many utility systems that can afford inspection and cleaning of their systems simply do not allocate the funds for it because there are no regulations requiring them to do so.

See potable water storage tank inspection and cleaning on this video.

This video shows how professional companies like “RON PERRIN WATER TECHNOLOGIES” using cutting edge equipment can make quick work out of inspecting and cleaning the most difficult water storage facilities.  The inspections can be performed with zero water loss or disruption in service.   Potable water divers can clean the floor of the facilities with minimal water loss providing a healthier storage area for municipal drinking water.  This makes a huge difference, a clean storage tank reduces the amount of treatment chemicals needed to meet current sanitary regulations.

Do you think the EPA should require Potable Water Storage tanks and towers to be cleaned?

Take the poll on this blog and be counted!
