Ron Perrin will be the instructor for WTR 308 Potable Water Storage Inspection Techniques.

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


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.

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.
