CONCORD -- The Contra Costa Water District Board on Wednesday will consider asking its customers to voluntarily reduce their water use 15 percent during this drought year.

The board will meet 6:30 p.m. Wednesday at district headquarters, 1331 Concord Ave.

District managers recommend that the board seek the savings among 250,000 customers in Central Contra Costa County, but not adopt special drought rates to penalize big users. Customers would be asked to base the reductions on their consumption in the 2005 to 2007 period.

Also recommended is enforcement of a ban on wasteful practices such as allowing runoff into street gutters, or watering between 9 a.m. and 5 p.m. instead of during cooler hours.

The water district also plans to ask local water systems that buy wholesale water from CCWD to seek similar savings of 15 percent from their customers in Antioch, Pittsburg, Martinez, Oakley and Bay Point.
