The Solana Center for Environmental Innovation and the County of San Diego are offering discounted rain barrels to encourage harvesting of rainwater. By using a rain barrel, county residents can reduce pollution from runoff, conserve water and save money on their water bills. The cost is $90 per 50-gallon rain barrel, but residents of incorporated cities can qualify for a $35 rebate per rain barrel on up to two rain barrels per household, bringing the cost to $55 each. Residents of unincorporated areas of the county can get an additional $30 discount, (limited to two discounts per household) for the first 200 rain barrels sold.
