There is more going on inside water storage tanks and towers than you may think.
Despite the fact that water in most U.S. cities is processed to a perfectly clean and healthy perfection it seldom stays that way once it leaves the water plant. Water is sent to the distribution system where it waits in water storage tanks and towers for the end user to open a tap, like the faucet in your kitchen sink or bathroom.
The problem is after the sparkling clean water leaves the high tech water plant it is pushed through an underground piping system to storage tanks. This part of the distribution system is often 30, 60 or in some cases close to 100 years old. Over time sediment builds up on the floor of water storage tanks. For years this was a part of the system that was simply out of sight and out of mind, and for some it remains so today.
Unfortunately, once a bacteria gets a foothold is a water system, growth can be rapid and dramatic. A small build up of sediment can provide a safe habitat for a wide range of organic contaminants. Annual inspections of the interiors are the key to keeping sediment levels in check.
Water utility managers often avoid interior inspection of water storage tanks, and for good reason. It takes time money and cost water. Traditionally tanks need to be taken out of service and drained, a process that may take several days if done properly. New technology allows managers to perform the inspection without any disruption in service or water loss. Tank inspection companies with underwater cameras can be contracted to inspect the interior of water storage facilities with no disruption in service and no water loss. The allows managers to keep up with what is going on in their systems at a fraction of the traditional inspection cost.
When deep sediment is found Potable Water Divers can be contracted to remove the sediment without draining the tanks, again saving water utilities time water ad money.
My company offers several different inspection methods to perform in service inspections of water storage tanks along with Potable water divers to clean the facilities if needed.There is more going on inside water storage tanks and towers than you may think.... more
The EPA is currently considering requiring ALL Water Tanks to be inspected!
Why is this a BIG DEAL?
Currently there are no EPA regulations requiring water tanks and towers to ever be inspected. Most states do not require tank inspection or cleaning. The water in the storage tanks goes from the tank directly to your tap.
All water tanks accumulate sediment over time. The soft sediment in the floor of water tanks and towers becomes a safe habitat for bacteria, protozoa and even VIRUSES!
Out of site out of mind-
No one thinks about the sediment.
The water is tested daily, if the chlorine residual goes down - operators do not ask why, they just add more chlorine, over time the additional chlorine breaks down and itself becomes a contaminate in the tank that can cause cancer.
Instead of constantly adding more and more treatment chemicals, simply cleaning the sediment from the floor of the tanks is the solution.
A countless number of biological contaminates 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.
