State and regional water plans should take RWH supplies available to the residential, commercial, industrial, institutional and agricultural sectors into account when planning for current and future water supply needs.
Both rainwater harvesting and stormwater management practices can greatly benefit your local watershed and the larger hydrological system. Rather than sending rainwater down the storm drain as polluted stormwater run off, infiltrating it into the landscape will recharge ground water. In rural areas, RWH assists in preventing erosion of the watershed, as well as reducing chemical-laden water runoff in agricultural areas.
