The groundwater reliability improvement program recycled water project, herein referred to as grip, is the cornerstone of the recipients effort to achieve independence from imported water for groundwater replenishment. The projects substantial completion for construction was december 31, 2018 and the project was commissioned in 2019. Grip introduces a new, local, drought-proof, high-quality advanced treated water source into one of the most highly urbanized groundwater basins in southern california, which serves more than four million people across 43 cities. The advanced water treatment facility (AWTF) produces advanced treated recycled water that is combined with tertiary treated recycled water purchased by the recipient from the sanitation districts of LOS angeles county (LACSD). This blended water is applied to the montebello forebay spreading grounds, an area with highly permeable soils that allows deep percolation of surface water. Seasonally in future operations, some advanced treated water will be injected into the aquifer for storage, using the three injection wells located at the facility. Currently, water supplies imported by metropolitan water district (MWD) originate in the sacramento-SAN joaquin river DELTA (DELTA) and are delivered through the state water project. At times, the colorado river also contributes a portion of the imported water supply. Grip eliminates the recipients use of imported water for groundwater replenishment activities in the central basin.
