The City of Chandler desired to create a public project which  could make use of the excess capacity of its waste water treatment plants. Using a series of pumps and retention basins, the Chandler Heights Recharge Project utilized treated waste water to create natural riparian preserves while replenishing the existing underground aquifer. Coupled with hiking trails, a six-acre man made lake, and an education center, CHRP allows local residents to experience the way in which water is cyclically placed back into the ecosystem. A 80,000 sf police substation was also constructed on site as a way to bring public transparency to local law enforcement.
