Some important benefits include creating a locally controlled, sustainable, and high-quality water supply and increasing water reliability because purified water is drought proof. Purified water also reduces dependency on water from the Sacramento-San Joaquin River Delta and helps protect the region’s groundwater supplies and environment. Recycling is good for the environment. The more recycled water we use, the less we need to take out of rivers, streams and groundwater basins. All water on the planet is reused. There exists the same amount of water on the plant as there always has been. Water is too precious a resource to use only once!
