Why is chlorine added to the water?

Chlorine is added to the water for your protection. The California Department of Public Health (CDPH) requires Valley County Water District to add a slight dose of sodium hypochlorite, or chlorine, to disinfect the water after it has been treated and filtered. The chlorine is added to the water through metering pumps and is dosed at approximately ½ of 1 part per million, which is equivalent to ⅔ of a cup of liquid in a standard 20,000-gallon swimming pool. Even at this small amount, chlorine has a very important job - it protects the water from bacteria and viruses. When it comes in contact with any bacteria it immediately attacks and destroys it. By dosing the water with chlorine, Valley County Water District knows that the water provided to your home or business is safe for you and your family to drink.
