What the Water Authority Does
The San Diego County Water Authority is a regional public agency that supplies wholesale water to 22 member agencies, including cities, water districts and a military base. Together, the Water Authority and its members support water service for approximately 3.3 million people.
The Water Authority manages regional water supplies, major delivery and storage infrastructure, long-term planning and water-use efficiency resources. Local retail providers manage customer accounts and service within their respective service areas. Identify the provider serving your property before requesting service or making a payment.

Local Water Service and Emergencies
Find the Provider for Your Address
Use the Water Authority’s Find Your Water District tool when you do not know which agency serves a property. The search instructions require both the street address and ZIP code.
The locator connects users with local agency information for water service, bill payments, restrictions and conservation resources. It does not itself open a customer account or submit a payment.
If the search does not identify a provider, check an existing water bill, ask the property owner or manager, or contact the relevant agency for help confirming the service arrangement. Do not assume every property receives water through a Water Authority member agency.
Account Requests and Billing Questions
Follow your provider’s official instructions to establish or close an account, update customer information, request billing assistance or dispute a charge. Use the agency named on your bill rather than a regional wholesale billing page.
Urgent Service Problems
For residential and commercial water emergencies, contact your local water agency. Use its emergency reporting instructions for urgent service problems, such as a suspected main break or an unexpected loss of supply.
The Water Authority publishes a separate after-hours emergency number for its regional operations. Its general message form is not a substitute for the appropriate emergency contact.
Water Bills and Rates
The Water Authority adopts wholesale rates charged to its member agencies. Retail providers establish their own customer charges, reflecting wholesale supply costs and local expenses such as distribution, maintenance and customer service.
A wholesale percentage increase does not necessarily translate into the same percentage change on a household or business bill. Individual charges depend on the provider’s rate structure, customer category, water use and other applicable fees.
Regional Rate Information
The Water Authority’s Rates & Affordability page explains its budget and wholesale rate process. The agency reports that its Board approved a 3% wholesale water rate increase for 2027 following a public hearing in summer 2026.
That decision concerns regional wholesale rates. Ask your retail provider about the rates and effective dates that apply to your account.
Wholesale Billing and Financial Reports
The member-agency resources cover wholesale rates, capacity charges and billing schedules. These resources are intended for member-agency transactions and are not a household bill-payment system.
For regional spending information, the Water Authority’s transparency resources link to budgets, financial reports and debt information. Check the reporting period when comparing figures.
Water Quality Reports
The Water Authority’s water quality page describes regional monitoring, treatment facilities, fluoridation, lead testing and per- and polyfluoroalkyl substances (PFAS).
The agency reports that treated water supplied through its regional system meets applicable state and federal standards. This regional information does not establish the water quality at every individual property or describe every independent water system or private well in the county.
Use Your Local Consumer Confidence Report
For information about the water supplied to your service area, review your provider’s annual consumer confidence report, also called a water quality report. Use the district locator to identify the provider and find its official website.
Check the report’s year, water sources, sampling results and explanatory notes. For questions about a current advisory, unusual taste or odor, or a property-specific concern, contact the provider directly.
Lead, PFAS and Fluoride
Lead can enter drinking water through corrosion of service lines and building plumbing. Treatment-plant results alone do not establish lead levels at a particular tap. Ask your local provider about service-line materials, available testing information and ownership responsibilities.
The Water Authority describes reverse osmosis at the Carlsbad desalination facility as a treatment that removes PFAS. That information should not be interpreted as a statement that every regional supply or household sample contains no PFAS. Review current local monitoring results for the system serving your property.
Fluoride concentrations can vary with the sources and blending practices used by a local provider. Consult its report or water quality staff for service-area information.
Conservation Programs and Rebates
The Water Authority’s water-use efficiency resources connect residential, commercial and agricultural customers with programs, incentives, surveys and educational materials. Additional offerings may be available through local providers and the Metropolitan Water District of Southern California.
Check the specific program before purchasing equipment or starting work. Review eligibility, qualifying products, funding availability, application deadlines and whether advance reservation or approval is required. A general program listing does not guarantee a rebate.
Residential Programs
Listed residential resources include incentives for certain efficient appliances, toilets, rain barrels and irrigation equipment, along with water-use surveys. Availability and rebate amounts may vary by service area and program.
Use the program administrator’s current instructions to confirm eligible models, required receipts and submission steps. Some landscape projects require an approved reservation before work begins.
Commercial and Agricultural Programs
Commercial, industrial and institutional offerings address indoor and outdoor water use at properties such as offices, restaurants and other facilities. The Agricultural Water Management Program provides services and incentives for agricultural customers within the Water Authority’s service area.
The separate Special Agricultural Water Rate Program offers qualifying agricultural customers lower-cost supplies with a lower level of reliability. It is a supply and rate arrangement rather than an equipment rebate. Ask the local provider about participation requirements and applicable supply conditions.
WaterSmart Landscaping
WaterSmart resources include the Nifty 50 and Happy 100 plant lists, landscape guides, classes and on-demand videos. They cover climate-appropriate plants, healthy soil, efficient irrigation and rainwater capture.
Use these materials to plan a landscape suited to local conditions. Check current watering restrictions with the retail provider and review any rebate requirements before removing turf or beginning installation.
Regional Supplies and Planning
The Water Authority’s regional portfolio combines conserved Colorado River water, other imported supplies, seawater desalination and local sources developed with member agencies. Local resources include surface water, groundwater and recycled water, with additional water purification projects under development.
The regional water supply overview explains this diversification strategy. Different communities may receive different combinations of sources, so regional portfolio figures should not be treated as the source breakdown for an individual property.
Long-Term Supply and Emergency Planning
The Planning & Preparedness resources include the Urban Water Management Plan, Water Shortage Contingency Plan, emergency planning documents and facilities plans.
The Water Authority reports that its adopted 2025 planning documents identify sufficient supplies for projected regional demand through 2050, including multiple dry years. These findings depend on planning assumptions and do not guarantee uninterrupted service at every property.
For current local restrictions, outages or emergency instructions, follow the provider serving your address.
Infrastructure and Projects
The Water Authority operates major pipelines, storage facilities, treatment infrastructure and related regional equipment. Its Projects & Programs page provides information about construction, facilities, maintenance and funding programs.
Use those resources for questions about regional facilities or infrastructure investments. Direct local service and account questions to your retail provider.
Meetings and Contacts
Board Meetings and Public Participation
A Board of Directors representing the Water Authority’s member agencies governs the organization. Regular meetings are generally held on the fourth Thursday of the month, with additional meetings and workshops as needed.
Use the official website’s Board Meetings and Public Meeting Engagement resources to confirm meeting dates, agendas, participation options and comment instructions. Follow the notice for the particular meeting rather than relying only on the usual monthly schedule.
