BACKGROUND INFORMATION: In the approved 1997/98 budget, $75,000 was included for an East San Joaquin Parties test project (see attached budget sheet H-28). This project and the history of this project was recently submitted to the City Manager and City Council under a memo from the Water/Wastewater Superintendent. This memo, dated September 19, 1997, is attached for your information. The test project itself will investigate the feasibility of utilizing the aquifer under east San Joaquin County for water storage. The project includes drilling of one injection/extraction well and one monitoring well. The water from East Bay Municipal Utility District's Mokelumne aqueduct will be used for the test. This project will demonstrate and quantify the ability of the aquifer to accept and distribute water through injection wells. The ability to recover water from the aquifer will also be demonstrated and quantified. If this project is successful, the East San Joaquin Parties would then be looking at the development of a well field for injection of wet winter waters from various sources to improve the groundwater subsidence in this area.

Lodi produces approximately 13,000 acre feet per year. This has provided the impetus for the formulation of a regional conjunctive use program involving EBMUD and Eastern San Joaquin County interests. Conjunctive use of water supplies involves maximizing the use of surface water when available and relying on groundwater in the drier years. In October of 1996, the Eastern San Joaquin Parties Water Authority (ESJPWA) was established, consisting of Woodbridge Irrigation District, North San Joaquin Water Conservation District, Central San Joaquin Water Conservation District, Stockton East Water District, California Water Service Company (associate member) and the cities of Lodi and Stockton. The purpose of the ESJPWA was to act as a planning agency to engage in negotiations with EBMUD regarding the conjunctive use plan and to study other means to meet the future water supply needs of Eastern San Joaquin County. The focus of the EBMUD project changed in 1996 from a project which relied heavily upon the use of groundwater storage in San Joaquin County to one that diverts water from the American River in cooperation with Sacramento County and the City of Sacramento. EBMUD, however, remains interested in the use of the Eastern San Joaquin County groundwater basin as a means to store water. The purpose for EBMUD's use of the groundwater basin has shifted in emphasis from a primary source to a supplemental source of water in dry years which could possibly result in the ability to downsize the needed conveyance and treatment facilities contemplated for the transfer of 300 cubic feet per second of water to the East Bay, with consequent cost savings to EBMUD. In order for this to work, a number of injection/extraction wells would need to be constructed to convey water to and from the groundwater basin. The feasibility of such a project is unknown without pilot testing. In order to study the feasibility of a large injection/extraction project that would meet the needs of EBMUD as well as Eastern San Joaquin County, ESJPWA decided to move ahead with a pilot project, on its own, in February of 1997. The envisioned project would be one in which water would be taken from the EBMUD Aqueduct, and through a series of injection wells, water would be forced into the aquifer near the Aqueduct and then extracted to confirm the feasibility of injection and extraction. The ESJPWA, working through San Joaquin County as the contracting agent, hired Boyle Engineering of Sacramento, to initiate the preliminary design of the pilot project. \\Pw msc\prime2\GROUP\WWW\MEMOS\ESJP.DOC 1113/97 Memorandum, City of Lodi, Public Works Department September 19, 1997 Page 2 Present Situation A site has been selected and secured for the pilot project. It is located adjacent to the EBMUD right-of-way, south of Live Oak Road and west of Jack Tone Road on the Charles Beckman properties (see attached map). Plans and specifications have been completed and on September 8, 1997, the ESJPWA Board approved and authorized staff to call for bids. The one or two Injection/Extraction Well(s) project is estimated to cost between $400,000 and $500,000 and will be funded by San Joaquin County Flood Control and Water Conservation District budget. The ESJPWA Board hopes to award the project on October 17, 1997. An agreement has been finalized with EBMUD to furnish to the project 1,000 to 3,000 acre feet of water at a cost of $1.00 per acre foot from December 1, 1997 through June 30, 1998. Upon completion of the project, EBMUD would be entitled to retrieve 50 percent of the water put into the ground. (I doubt EBMUD would find it cost effective to pump 500-1500 acre feet back into their pipeline, but may do it for principal.) The success of this pilot project would become a valuable bartering tool for ESJPWA with EBMUD and could lead to a full-scale Injection/Extraction Well System. This could begin the restoration of our continually declining water table beneath the Lodi region. Councilman Keith Land, Public Works Director Jack Ronsko, and I have been and will continue to be actively involved in the ESJPWA.
