ARCSA, the association that promotes sustainable rainwater harvesting practices, has announced its support of California's plan to harvest
rain and stormwater.

As the majority of California is in a D4 intensity of drought, the highest level, the State Water Resources Control Board adopted statewide emergency regulations to dramatically reduce potable water use and increase the supply.

This new plan, supported by the American Rainwater Catchment Systems Association, does not diminish downstream supplies, but merely "borrows" it along the way. According to ARCSA – an average 12 inches of annual Southern California precipitation, a 1,500-square-foot residential roof could collect over 10,000 gallons annually and for a 100,000 square foot commercial building, the quantity is over 700,000 gallons.

The legislature has also approved a $7.5 Billion water bond referendum for the November ballot, setting aside funds for new local water supplies. Among other plans, the state is formulating a Stormwater Strategy Initiative to augment local water supplies.
