Reclaimed water or recycled water, is wastewater (sewage) that is treated to remove solids and certain impurities, and used in many settings for sustainable landscaping irrigation or to recharge groundwater aquifers. The purpose of these processes is sustainability and water conservation, rather than discharging the treated water to surface waters such as rivers and oceans. The Sterling Natural Resource Center is a reclamation facility which will be used to replenish the local groundwater basin.
