Eastern San Joaquin Groundwater Basin Groundwater Management Plan Northeastern San Joaquin County Section 8 Groundwater Banking Authority 137 Integrated Conjunctive Use Program The Farmington Program Base Project (Farmington Program) objective is to recharge an average of 35,000 af of water annually by directly recharging surface water on 800 to 1,200 acres of land in the area described above. The Farmington Program is a flexible program by which willing landowners with 20 to 100 acre parcels may enter into short-term and long-term agreements and receive market-based compensation for the use of their land for groundwater recharge. In addition all improvements are paid for through the Farmington Program. The arrangement allows the rotation of groundwater recharge practices with traditional land use making water a cash crop for farmers in the program. The Farmington Groundwater Recharge Program is currently seeking out landowners who are willing to participate in the program by providing fields that can be flooded. The planned capacity of the Farmington Program is approximately 35,000 af/yr. The following water sources are assumed available for the Farmington Program: • 10,000 af/year from Stanislaus River • 10,000 af/year from Littlejohns Creek • 5,000 af/year from Calaveras River • 10,000 af/year from Mokelumne River 8.3.2 City of Stockton Delta Water Supply Project In 1996, the City of Stockton filed a water right application with the SWRCB seeking to appropriate initially 20,000 are-ft per year of water from the Delta, increasing to 125,900 af per year in 2050. The application specifies a place of use that coincides with the adopted 1990 City of Stockton General Plan boundary as shown in Figure 8-22. The city filed the water right application under two legal authorities: California Water Code Section 1485, the recapturing of treated wastewater discharge in the Delta, and California Water Code Sections 11460 and 12200 et seq., area of origin provisions and the Delta Protection Act, respectively. The city currently discharges approximately 35,000 af per year of treated wastewater into the San Joaquin River. Diversions from the Delta are extremely contentious and therefore somewhat restrictive due to constraints under the State and the federal Endangered Species Act (ESA). The City of Stockton also expects to be limited by SWRCB Term 91 conditions, which limits diversion to when Delta outflow is higher than regulatory minimum requirements. (City of Stockton, 2003) In 2003 the City of Stockton completed the Delta Water Supply Project (DWSP) Feasibility Report. The DWSP consists of a new diversion structure in the delta at the southwestern tip of Empire Tract on the San Joaquin River, a raw water conveyance pipeline, a new water treatment plant along Eight Mile Road, treated water transmission facilities, and groundwater injection and extraction wells, as shown in Figures 8-23 and 8-24. The estimated capital costs of the facilities are: • River Intake and Pumps: $18 million • Raw Water Conveyance: $35 million • Water Treatment Plant (30 MGD): $59 million • Treated Water Pipelines: $9 million
