Water Treatment Page - City of Tempe Water Treatment Producing Safe Drinking Water for Tempe Water treatment is the process of cleaning water and making it safe for people to drink. The water picks up substances during its journey through the rivers, lakes, and canal system. Canal water begins its treatment path here. These basins slow down the incoming water and allow some of the large particles of dirt, etc. to settle out. It causes the particles to clump together and form large particles called floc.
Chlorine is added again as the water enters the water reservoirs and distribution system.
