SUPPLYING LOCAL COMMUNITIES WITH VITAL GROUNDWATER
The Spadra Basin lies beneath the San Gabriel Valley, in the western portion of the City of Pomona. This aquifer supplies groundwater primarily to the City of Pomona, Walnut Valley Water District and Cal Poly Pomona. Rowland Water District is also a primary stakeholder in the basin. Water from the basin is used by local residents and for industrial and irrigation purposes.
The City of Pomona and the Walnut Valley Water District are collaborating to sustainably manage the basin, by forming the Spadra Basin Groundwater Sustainability Agency (GSA). This partnership will help protect groundwater quality, manage local water supplies and expand water storage at the basin.
