	INTRODUCTION The Upper District's service area and water supply are being challenged by several factors. First, the Wanger Decision has led to reductions in historic supplies from the Northern California Delta. Court-ordered water diversion curtailment continues to reduce State Water Project allocations. Second, the Colorado River watershed is experiencing historic drought. Third, the Metropolitan Water District of Southern California (MWD) is allocating surplus water primarily to MWD accounts, possibly limiting availability for Main San Gabriel Basin replacement water. With desalted sea water still an expensive and environmentally controversial option at this time, stormwater capture programs in their early stages, and water conservation being only a partial solution, recycled water is considered a "growth" market for water supply, particularly for irrigation and recharge projects. The Groundwater Reliability Improvement Program (G.R.I.P.) is a cooperative effort between the: Upper Area: Upper San Gabriel Valley Municipal Water District (Upper District) with the San Gabriel Valley Municipal Water District (SGVMWD) Lower Area: Water Replenishment District of Southern California (WRD) Los Angeles County Sanitation Districts (LACSD) The basic project concept is to obtain recycled water supply from the San Jose Creek Water Reclamation Plant (SJCWRP) which is operated by the LACSD.
PLANNED OPERATIONS	The LACSD will provide tertiary recycled water and operate the Advanced Tertiary Water Treatment Plant at its San Jose Creek Water Reclamation Plant. The process includes: Microfiltration/Ultrafiltration Reverse Osmosis Advanced Oxidation Process and Ultraviolet Disinfection Decarbonation Lime Addition The advanced treated recycled water that is produced must then be conveyed to replenishment facilities. A pump station and conveyance pipeline (approximately 6 to 8.5 miles in length) would have to be constructed to enable recharging of water basins in the vicinity of the Santa Fe Dam (see Upper Area map/photo). A gravity pipeline (approximately 3.5 miles in length) would have to be constructed to recharge basins along the San Gabriel River (Lower Area).
STATUS OF G.R.I.P. (1 ST QUARTER 2010)	G.R.I.P. accomplishments include: Formation of G.R.I.P. Team inclusive of General Managers from the Upper District, SGVMWD, WRD and LACSD A completed Memorandum of Understanding (MOU) between the Upper District, WRD and LACSD that specifies interests, goals and shared funding of a "Conceptual Design Report" The Conceptual Design Report, which includes a detailed review of advanced treatment requirements, description of conveyance facilities, Phase I conceptual level cost estimates (Upper Area) and a briefing on regulatory requirements A background water quality monitoring plan which is required for California Department of Public Health/Regional Water Quality Control Board permitting Coordination/Securing tertiary water from LACSD, with Phase I secured, and LACSD addressing Phase II supply Regulatory coordination with entities such as California Department of Public Health, Regional Water Quality Control Board and LA County Department of Public Works (Office of Recycling). Selection of an Alternatives Analysis consultant. The Alternatives Analysis report is scheduled to be completed by the end of 2010. Development of draft Joint Powers Authority documentation involving the Upper District, SGVMWD, WRD and LACSD.
PHASED IMPLEMENTATION OF G.R.I.P.	Phase I and Phase II will provide a total of 46,000 AFY of new water (25,000 AFY to the Upper Area and 21,000 AFY to the Lower Area). The LACSD can currently produce the necessary tertiary water for Phase I but LACSD improvements are needed to produce the tertiary water needed for Phase II.
