Recent Water Tower Cleaning had a few surprises

We recently cleaned a potable water storage tower that had not been cleaned since it was built in the mid 1980’s.  This facility was in compliance, it had been inspected once a year, but due to the fact that there are no set rules on when to clean water storage tanks in Texas it had never been cleaned.

We used a Celestron LED digital microscope to take a close look at the sediment removed from the floor of the tank.  I posted what we found on my blog titled: THE CLEAN WATER TANK PROJECT at www.ronperrin.us.  Due to the fact that rules on inspecting and cleaning potable water storage facilities vary greatly from state to state we may soon see changes in this area of Federal Regulation.

Currently most states do not have specific rules on when potable water storage tanks should be cleaned.

Please visit my CLEAN WATER TANK PROJECT blog and take the poll a few post down from the top.  I would like feedback if you think the EPA should make a standardized requirement of cleaning and inspection of the nations drinking water tanks and towers.

*       The American Water Works Association recommends that tanks be cleaned at least every three years.  Recent focus on pharmaceuticals in water systems have made more people than ever aware of contaminates that may be lurking in their water supply.   Although pharmaceuticals in drinking water may be in the news the real threat is random bacteria and cryptosporidium spores.

The Threat of Bacteria-

Countless kinds of bacteria can make their way into a public water supply.  Chlorine and other treatment methods are our first line of defense.  When potable water storage tanks are clean small amounts of bacteria that survive the treatment process cycle through the system undetected and harmless due to the small quantity.  Sediment in the tank can capture and harbor these small amounts of bacteria.  The bacteria can start to grow hidden from chlorine deep in the sediment.  Chlorine can even be overwhelmed and depleted if a nitrate eating bacteria is collected.   As the bacteria continues to grow in the sediment month after month and year after year the threat to public health grows.       

  The Threat of Cryptosporidium

The threat of cryptosporidium outbreak is even greater with sediment in the floor of a water storage tank.   Again Sediment can harbor bacteria, cryptosporidium and other contaminates.  The best defense to insure a protozoa like  cryptosporidium will not take up residence in your water storage system may be to keep the tanks free of sediment.  In the Spring of 1993 over 100 people died as a result of a cryptosporidium outbreak that was directly associated with the Howard Avenue Water Purification Plant.  This was the largest water born disease ever documented in United States history.  It is estimated that over 400,000 people became ill with diarrhea.  

Due to the fact that cryptosporidium is a protozoa parasite with a thick outer shell it is highly resistant to disinfectants such as chlorine.  The best defense to ensure it will not inhabit your water system may be to make sure your water tanks remain sediment free.  This will remove and habitat that small amounts bacteria or protozoa could lodge and grow in, Preventing possible public health problem in the most simple way.  Keeping water storage tanks clean.
