摘要

The City of Oxnard, a coastal community in southern California, is implementing a strategicrnwater resources program known as the Groundwater Recovery Enhancement and Treatmentrn(GREAT) program. The capstone of the GREAT program is an advanced water purificationrnfacility (AWPF) that will utilize a major portion of the secondary effluent from the City’srnexisting water pollution control facility (WPCF) to produce a high quality treated water. Therntreated water will be used for multiple beneficial uses including irrigation of edible foodrncrops, landscape irrigation, injection into the groundwater basin to form a barrier to seawaterrnintrusion, as well other possible industrial uses to be identified in the future.rnThe AWPF, currently under design by CH2M HILL, will employ a multiple barrier treatmentrntrain consisting of microfiltration/ultrafiltration (MF/UF), reverse osmosis (RO), andrnultraviolet (UV)-light-based advanced oxidation (AOX) processes to purify the secondaryrneffluent as required to conform to CA Department of Public Health (DPH) “Title 22”rnRecycled Water criteria for groundwater recharge.rnThe AWPF, which will have initial and build-out capacities of 6.25 and 25 mgd, respectively,rnhad to be designed to fit on a 4.3-acre site, with more than one acre dedicated to arncombination visitor’s center and administration building and other uses not associated withrnthe primary treatment processes. Further, the depth below grade and height of the AWPF’srnstructures (buildings, chemical storage structures) were constrained because of the highrngroundwater table at the site and the high cost of excavation and dewatering, as well as localrncodes. To accommodate these various restrictions, an innovative design approach has beenrndeveloped. This paper summarizes the design constraints and innovative solutions for therndesign of the AWPF.
