Lake Arrowhead Woods water is of relatively high quality, but requires treatment by filtration and disinfection to meet the State and Federal drinking water regulations.

Water is pumped from intake facilities in North Bay and Emerald Bay of Lake Arrowhead Woods and is treated at either the Bernina Water Treatment Plant or the Cedar Glen Water Treatment Plant. Groundwater is also pumped into the treatment facilities.

The District’s treatment plants use clarifiers and dual media gravity filters for filtration. The media used in the filters is anthracite coal and sand. These units have produced a quality of water that is better than that required by the State Department of Health Services.

In 1989 the District completed construction of a new $1.4 million absorption clarification unit at the Bernina Plant. The unit was built to meet more stringent requirements by the State to provide multi-barrier filtration necessary for the removal of giardia and cryptosporidium. The Cedar Glen Water Treatment Plan was updated and brought on line in 2000.

Water is also imported, when necessary, through the Crestline-Lake Arrowhead Woods Water Agency (CLAWA). Imported water comes from Lake Silverwood and is treated at CLAWA facilities before it is pumped directly into the District’s distribution pipelines for delivery to customers.
