Water Rate Planning
NID is committed to providing reliable, high-quality water service to the communities we serve. A stable financial strategy is essential to supporting more than 6,000 raw water customers who irrigate local fields and farms, as well as over 21,000 treated water connections serving homes and businesses.
NID adopts a budget every year and plans capital projects for the next five years. The District’s budget and rates are designed to strike a careful balance: generating revenues fairly to invest in the region’s water future while managing rates through steady, modest increases that reflect the cost of service.
Revenue from NID’s hydroelectric power generation helps subsidize the cost of water delivery, keeping rates lower for customers.
Your water rates at work
NID charges only what is necessary to cover the cost of providing water service. These funds support:
- Water treatment: Delivering high-quality drinking water around the clock.
- Operations and maintenance: Day-to-day costs of running the system, including pipes, canals, pumps, reservoirs, and treatment plants.
- Capital projects: Building, repairing, and replacing major water infrastructure.
- Conservation and efficiency programs: Promoting water-use efficiency and offering rebates for water-saving landscapes and appliances.
- System improvements: Investments in technology, watershed health, and long-term water supply reliability to ensure sustainability for future generations.
The rate setting process for 2027, following the Proposition 218 process, included two public workshops on July 22, 2026, and July 28, 2026. The 2027 rates for treated and raw water customers are based on the 2026 Cost of Service Study, which ensured operating and capital costs were covered and sufficient reserves were maintained. On August 6, 2026, NID's Board of Directors approved a 2027 rate increase of 9%, a reduction from the Cost of Service Study Noticed Rates of 12.5%, which required an offset over the five-year rate term.
