Motivated by population growth, the Inland Empire Utilities Agency (IEUA) has developed a comprehensive program intended to
meet projected demands without increasing the use of imported water, or the use of
groundwater beyond a point that would require substantial treatment. The alternative, as
presented in IEUA's Recycled Water Implementation Plan (RWIP) utilizes recycled
wastewater as an alternative water supply and rely on a two-pronged approach. One is
utilizing effective tertiary treatment to ensure that the recycled wastewater effluent meet
potable water standards. The other is to build special facilities designed to increase the
use of recycled water throughout the service area. The RWIP describes a series of pipelines, reservoirs and other conveyance
features that will take wastewater treated at four existing wastewater treatment plants and
make it available for reuse.
The combination of the existing facilities and the new facilities described in the RWIP
will take over 175 mgd of wastewater flow, treat it to tertiary standards and make it
available to supplement potable water supplies. Initially, the agency started
developing the conveyance facilities and utilizing conventional tertiary treatment to
supply water for irrigation and other non-potable uses. The agency
simultaneously started extensive efforts directed at the optimization of tertiary treatment
using cutting edge treatment technologies such as ceramic membranes and membrane
bioreactors (MBRs), which are expected to greatly improve the water quality of the
finished effluent and meet potable water standards. Includes 15 references, tables, figures.
