In an effort to refine and improve its water chlorination process, the Coachella Valley (Calif.) Water District purchased a water chlorination system from The Hammonds Companies, of Houston. Today, the Coachella Valley Water District has seven units in place and another 12 to 15 units on order. In the future, the water district will continue to look for alternatives to chlorine gas for the remaining wells and the system appears to be a viable alternative.
