Title: Energy savings effects of artificial recharge and increased storage in groundwater basins
Abstract: A key consideration of a hydrologic assessment associated with the proposed rehabilitation of groundwater recharge spreading grounds has been the energy savings effects of reduced pumping lifts as a result of increased storage in the groundwater basin. A hydrologic assessment of the San Antonio Creek sub-watershed (SACSW) was performed by Daniel B. Stephens & Associates, Inc. (DBS&A). This assessment provided key hydrologic and other technical data relating to the proposed San Antonio Creek Spreading Grounds Rehabilitation Project (SACSGRP) in the Ojai Groundwater Basin as part of the Ventura County Integrated Regional Water Management Plan for Proposition 50 grant application. SACSGRP objectives include rehabilitating dilapidated and abandoned groundwater recharge spreading grounds that previously operated within the Ojai Valley. The Ojai Valley is within the SACSW, which is a sub-watershed of the Ventura River Watershed. Several water supply and energy sustainability issues relating to the SACSGRP are addressed, including: (1) the annual stream flows within the SACSW, (2) the degree of impact of diversions for the spreading grounds on riparian habitat within the SACSW and the Ventura River Watershed, (3) the quantity of potential Basin recharge resulting from the spreading grounds, (4) the resulting increased reliability for local and regional water supplies, and (5) a quantification of energy savings as a result of decreased total dynamic head of pumping wells extracting groundwater from recharged aquifers.
