WATER RESOURCES TECHNICAL REPORT3.1.5 Port Hueneme Water AgencyAs noted above, PHWA provides potable water to the City of Port Hueneme, the ChannelIslands Beach Community Services District, the Naval Construction Battalion Center PortHueneme, and the Naval Air Weapons Station Point Mugu. PHWA has two primarysources of water for its supply: (1) desalted groundwater and (2) imported surface water.The City of Port Hueneme, the Naval Construction Battalion Center Port Hueneme, and theNaval Air Weapons Station Point Mugu all have individual wells; but these are primarilystandby facilities. The PHWA primary source of supply is groundwater from UWCD via theO-H pipeline. This water is desalted at the BWRDF to be compatible with the quality of theimported surface water from CMWD that is delivered via the Industrial Lateral. This sourceis used to supplement flows produced at the BWRDF. Water from both sources is combinedat the BWRDF site and fed into the distribution system. PHWA has been able to maximizeits use of the local groundwater by operating the BWRDF around the clock at a steady flowrate and storing excess water in the Pt. Mugu reservoir. Table 3-3 provides PHWA waterquality data from the City of Port Hueneme 2001 Consumer Confidence Report.PHWA operates the BWRDF, a successful project partially sponsored by the Bureau ofReclamation. The 4-mgd BWRDF desalinates local groundwater supplied by UWCD via theO-H pipeline. It is operated as part of a water quality improvement program to meet PHWAwater supply requirements and improve water quality. Although the BWRDF is operated byPHWA, it is actually located on City of Oxnard property. A lease for the use of the propertywas arranged in 1996 (Water Treatment, Plant Site Facilities and Land Lease Agreement,February 13, 1996) that reflected the intention of the City to develop a water reclamationfacility on the site. Provisions in the lease allow the City to unilaterally develop waterreclamation facilities on the remaining two-thirds of the parcel that the BWRDF is sited on.Over time, PHWA has been able to accumulate a sizeable unused groundwater allocation.The projected FCGMA groundwater allocations are shown below. These allocations aresubject to the same series 5 percent reductions scheduled for 2005 and 2010 as with thegroundwater allocations of the City.FCGMA Groundwater Allocation for PHWAParameter 2000 2005 2010 2020UWCD Allocation a 4,342 4,011 3,880 3,880PHWA Allocation b 1,637 1,529 1,313 1,313Total 5,979 5,540 5,193 5,193Notes:Includes baseline transfers of 421 AFY.Includes MWD transfers of 700 AFY.3.1.6 Ocean View Municipal Water DistrictOVMWD currently serves potable water to domestic and agricultural users on the OxnardPlain via the Ocean View pipeline. The Ocean View pipeline is a 16-inch-diameter asphaltconcrete pavement (ACP) line. Although the Ocean View pipeline serves some domesticusers, the number of service connections is small (estimated at 10 connections in the 1993Water Reclamation Master Plan and in the 1989 Inventory of Public and Private WaterPurveyors in Ventura County by the Ventura Local Agencies Formation Commission).
