After a period of time, the accumulated solids begin to clog the filter and the filter is backwashed. This is reversal of the direction of the water flow through the filter. A rapid upward flow lifts the media and keeps it in suspension until the accumulated material can be washed out. After the filtration process, the water is no longer exposed to the atmosphere. It flows underground from the filters into the Crom tank which is a 4.5 million gallon storage tank.
Stabilization is a protective measure that reduces the problems of corrosion in water lines.
Corrosive waters can cause problems related to public health, aesthetics and economics. Calciquest is a corrosion inhibitor that is added to the finished water to prevent these problems. Fluoridation is a safe, effective and economical process that is endorsed by public health groups worldwide to reduce tooth decay. Fluoride is received as liquid hydrofluosilicic acid and stored on site in an 8,000-gallon storage tank. Each midnight a 900-pound capacity tank is filled and weighed.
