SSJID

At SSJID - the South San Joaquin Irrigation District.- we provide water for irrigation & drinking and generate clean electric power.

In 1909, the South San Joaquin Irrigation District was established to provide a reliable and economical source of irrigation water for the areas around 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 192

6, 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 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.

Last month, SSJID General Manager Peter Rietkerk joined industry professionals, farmers, and federal agency representatives at the California 5th District Water and Agricultural Forum, hosted by Congressman Tom McClintock.

Discussions focused on the future of California’s resources, the needs of the Central Valley, and continued coordination among those who serve the region. Rietkerk represented SSJID, alongside Tri-Dam Project General Manager Summer Nicotero.

SSJID Board Member Glenn Spyksma was also in attendance, along with representatives from Stockton East Water District, Oakdale Irrigation District, Modesto Irrigation District, and Turlock Irrigation District.

Events like this create an important space to exchange perspectives, strengthen partnerships, and advocate for the communities and growers we serve.

September is National Preparedness Month, an annual reminder of the importance of being ready for emergencies and unexpected events. Preparation starts with the essentials, including reliable services you can count on when they’re needed most.

That commitment to reliability is central to SSJID’s Powered by Purpose initiative. For more than 115 years, the District has safely and reliably delivered water to the communities it serves. SSJID is working to bring that same level of dependable, locally accountable service to electric power, with decisions and operations centered right here in the region.

Harvest season is just around the corner, and that means you'll begin seeing more tractors, harvesting equipment, and farm vehicles traveling our local roads.

As crews work long hours to bring this year's crops in from the field, we encourage everyone to slow down, stay alert, and give plenty of space. A little extra patience goes a long way in helping everyone get home safely.

At SSJID, we're proud to support the growers who help feed our communities, and we wish them a safe and successful harvest season! 🚜

Hydropower has been part of SSJID's story for decades, helping transform the flow of the Stanislaus River into a dependable source of low-carbon renewable energy.

On National Hydropower Day, we're recognizing the impact of the Tri-Dam Project, SSJID's partnership with Oakdale Irrigation District. Together, the project helps generate clean hydroelectric power while making the most of one of our region's most valuable natural resources.

SSJID's canals serve an important purpose by delivering irrigation water throughout our region and supporting the communities and agriculture that depend on it. While they are an essential part of our water system, they are not designed for swimming or play.

Whether you're out for a walk, riding your bike, or spending time outdoors, remember to keep a safe distance from canal banks and keep children and pets away from the water.

Visit https://loom.ly/24aNGkQ to learn more about canal safety and how you can help protect yourself and your family.
