SSJID currently provides irrigation water to southern San Joaquin County, and has done so since 1909; with the completion of the Nick C. DeGroot Water Treatment Plant at Woodward Reservoir, we began providing drinking water to Tracy, Manteca, and Lathrop in 2005.

SSJID, after selling power wholesale for a half-century, is also currently attempting to purchase Pacific Gas and Electric Company's distribution system in the South County and enter the retail power business, servicing Manteca, Ripon, Escalon and adjoining rural areas.
