Document Description
The Yucaipa Valley Water District (YVWD) proposes to construct an Aquifer Storage and Recovery Facility located west of Interstate 10 in the City of Calimesa as one project in two phases. Phase 1 proposes to install one test injection well (IW-1) and one monitoring well (MW-1) for the purpose of acquiring objective aquifer data and to determine site-specific groundwater level effects from proposed future recycled water injection. The data collected during pumping and injection tests will be used to refine current groundwater model parameters and to determine baseline basin groundwater quality in the zones where future injection wells are planned to be constructed. The monitoring well will be placed at a targeted location to better refine estimates of aquifer characteristics, mounding effects, and travel times. Results from this study will be used to select the optimal placement of the remaining four proposed injection wells that will be constructing in this phase (Phase 1). Phase 2 proposes to install two recovery wells. This system includes the injection of approximately 2,500 AFY of fully treated (reverse osmosis) recycled water to provide additional drinking water supplies and to meet peak recycled water demands by reversing the flow of water from the injection wells. Implementation of this Phase 2 will also provide purified recycled water recharge to Yucaipa Subbasin and recovery facilities, thus decreasing dependence on imported water deliveries. The ASR wells will be constructed in an approved Specific Plan area with a certified EIR. This CE covers the installation and operation of the wells.
