End of Irrigation Season is October 15

During the Board of Directors meeting on September 22, SSJID’s Board approved October 15 as the end date for the 2020 irrigation season.  The Board considered crop water requirements approaching the end of the season, available water supply, irrigation/maintenance operations, and Woodward Reservoir and Water Treatment Plant operations before making a unanimous decision to support the date of October 15.

The Division Managers will be scheduling final water deliveries prior to October 15, so please contact them with any questions or specific irrigation needs.


Welcome to South San Joaquin Irrigation District

In 1909, the South San Joaquin Irrigation District was established to provide a reliable and economical source of irrigation water for agricultural use in, and surrounding rural areas of Escalon, Manteca and Ripon. SSJID’s historic water rights allow for several hydroelectric power plants on a series of dams and reservoirs on the Stanislaus River. SSJID and Oakdale Irrigation District completed the original Melones Reservoir in 1926, and have co-owned the Tri-Dam Project, consisting of Donnells, Beardsley and Tulloch reservoirs and powerhouses since 1957. In 2005, as unprecedented urban growth replaced agricultural land, the District expanded into providing domestic water service to South San Joaquin County cities with its state-of-the-art membrane filtration water treatment plant. In 2009, SSJID completed a 1.4 megawatt solar farm that provides nearly all of the electricity to run its water treatment plant, and the District passes on a 15% savings on power costs to the cities who participate in the treatment plant. For several years, the District has been moving towards providing retail electric service as well, aiming to cut electric bills of those in its service territory by 15% across the board.
