AWWA ACE69029

Motivated by population growth, the Inland Empire Utilities Agency (IEUA) has developed a comprehensive program intended tomeet projected demands without increasing the use of imported water, or the use ofgroundwater beyond a point that would require substantial treatment. The alternative, aspresented in IEUA's Recycled Water Implementation Plan (RWIP) utilizes recycledwastewater as an alternative water supply and rely on a two-pronged approach. One isutilizing effective tertiary treatment to ensure that the recycled wastewater effluent meetpotable water standards. The other is to build special facilities designed to increase theuse of recycled water throughout the service area. The RWIP describes a series of pipelines, reservoirs and other conveyancefeatures that will take wastewater treated at four existing wastewater treatment plants andmake it available for reuse.The combination of the existing facilities and the new facilities described in the RWIPwill take over 175 mgd of wastewater flow, treat it to tertiary standards and make itavailable to supplement potable water supplies. Initially, the agency starteddeveloping the conveyance facilities and utilizing conventional tertiary treatment tosupply water for irrigation and other non-potable uses. The agency simultaneously started extensive efforts directed at the optimization of tertiary treatmentusing cutting edge treatment technologies such as ceramic membranes and membranebioreactors (MBRs), which are expected to greatly improve the water quality of thefinished effluent and meet potable water standards.
