The Water Cycle

Oceans cover three-quarters of the earth’s surface. From these vast reservoirs, water rises into the sky through evaporation, leaving behind salt in the process. It then collects into clouds which, carried by the winds, precipitate on the land in the form of rain, snow, hail, sleet, fog, and dew. The Water Cycle, also known as the Hydrologic Cycle, includes many mechanisms for both evaporation and return to the ocean as shown in the diagram below.


Water Sources & Typical Treatment

Our water is obtained from surface water (streams, river, and reservoirs) and groundwater (wells). To assure that water quality meets regulatory requirements and is protective of human health, it must be treated using various processes. Typical treatment processes depend on whether the source water is surface water or groundwater.
