Preparation of a Title 22 Engineering Report for the Recharge of Recycled Water

Groundwater in the
San Timoteo Watershed

San Timoteo Watershed Management Authority

The San Timoteo Watershed Management Authority (STWMA) was formed as a Joint Powers Agency (JPA) in January 2001 by the Beaumont-Cherry Valley Water District (BCVWD), the City of Beaumont (Beaumont), the South Mesa Water Company, and the Yucaipa Valley Water District (YVWD).

Wildermuth Environmental, Inc. (WEI) was retained by the Beaumont Cherry Valley Water District and the City of Beaumont to conduct four key water resources projects, which include the preparation of a Title 22 Engineering Report for the recharge of recycled water to improve ground water quality and increase water availability in the Beaumont area.

Program Element Phase 1 of this program element has two components, which are currently in progress. The first component includes a high priority project to implement the recycled water and imported water portion of BCVWD's "Surface Water Capture for Little San Gorgonio Creek and Other Locations" project. To enhance the basin's water supplies, this project integrates the water supply reliability, water recycling, groundwater management, imported water recharge and stormwater capture management strategies with the wetlands, recreation, public access and flood control management strategies. The second component of Phase 1 of this program element includes a Phase 1 Investigation to develop a master plan for operation and facilities to manage surface water discharge and recharge in the STWMA area and includes: a two-year field program; development and application of modeling tools to characterize future surface water quality problems and to analyze solutions; and the development of a two-prong stormwater and dry-weather discharge management strategy.

The objective of this task order is to prepare a Title 22 Engineering Report for planned groundwater recharge projects that will use recycled water.
