​​Conserving Tomorrow's Water Today

2024 Water Rates Study

SCWA recently completed a water rates study, an industry best practice to ensure that the rates our customers pay are fair, equitable, and fully recover the costs that different customer types place on our system. Our Board of Directors will consider water rate adjustments at a public hearing scheduled for September 10, 2024, at 11 a.m. Visit www.SacCoWaterRates.org for more information.​

Arden Service Area Pipe and Meter Installation Project​

SCWA will abandon old pipelines located in backyards, install approximately 38 miles of new distribution pipelines within the street right-of-way, install nearly 3000 new meters, and replace or install new fire hydrants.  Learn more about the Arden Service Area Pipe and Meter Installation Project. ​

Conjunctive Use Program - Preparing For Drought

SCWA operates a conjunctive use program in Zone 40. For SCWA the conjunctive use means relying heavily on surface water in years where the​re is plenty of water and more heavily on groundwater in years that are dry. Generally, SCWA takes its surface water through an intake on the Sacramento River near Freeport. That water is then treated and distributed to customers. SCWA also has an agreement with the City of Sacramento to provide some treated surface water from SCWA rights and contracts and that water is provided through a connection between the City of Sacramento and SCWA. In dry years less surface water is available and SCWA operates a system of wells and groundwater treatment plants to extract and serve groundwater.

The conjunctive use program is a balance and strategy to supply water to SCWA customers with the least adverse impact to either the river system or the groundwater aquifers. 

Storing groundwater below ground through conjunctive use is also seen as a way to lessen its evaporation and avoid building reservoirs and dams.​

• Planning:​ Planning activities are generally determined by growth decisions made by local land use authorities (the cities of Elk Grove and Rancho Cordova and the County of Sacramento) and are focused on identifying and developing long-term water supplies for these development areas. Meeting these long-term needs is accomplished through the development of water supply master plans for Zones 40 and 50, the Zone 40 Water System Infrastructure Plan, and the Zone 41 Urban Water Management Plan. Planning is also responsible for reviewing and conditioning development proposals to ensure compliance with the latest water supply planning requirements and development of Water Supply Assessments and Written

Water Supply SCWA Zones

Sacramento County Water Agency was formed in 1952 by a special legislative act of the State of California.  The Sacramento County Board of Supervisors was designated to act as the ex-officio governing body or Board of Directors for SCWA.  The Water Agency Act empowers the Board of Directors to create geographic zones with specific projects and benefits.  Currently SCWA has eight zones:

• Zone 13 was created by the Water Agency Board of Directors on May 5, 1987 to fund comprehensive long-range planning and engineering studies of flood control, water resources development, water supply management and water conservation beneficial to the Zone. Zone 13 includes all of Sacramento County excepting the cities of Sacramento, Folsom, Galt and Isleton, and its activities are funded by an annual per-parcel assessment on all real property within the Zone.
• Zone 40 was created by the Water Agency Board of Directors on May 14, 1985 pursuant to Resolution No. 663 to fund the planning, design, and construction of major water supply facilities that benefit the Zone. Zone 40 revenue is provided from water development fees collected at the time of development and from Special User Fees included in bi-monthly water customer utility charges.

• Zone 41 was created by the Water Agency Board of Directors on June 13, 2000 pursuant to Resolution WA-2397, and constituted a reorganization of the Sacramento County Water Maintenance District. Zone 41 funds the operation and maintenance of a public drinking water system that includes water production, treatment, storage and distribution facilities, pursuant to permits issued by the California Department of Health Services. Revenue to fund Zone 41 activities is provided by utility charges, connection permit fees, construction water permits, and grants-all of which fund Water Supply Capital Facilities Design and Water Supply Facilities Operations and Administration.  Zone 41 also provides wholesale water supply to the Elk Grove Water Service pursuant to the First Amended And Restated Master Water Agreement Between Sacramento County Water Agency And Florin Resources Conservation District/Elk Grove Water Service, June 28, 2002.
