Provider briefing
How this utility’s billing works
City of Hayward Water System – Revenue Division / Public Works and Utilities Department operates as a municipal department serving Hayward, with a small northern area served by East Bay Municipal Utility District. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Increasing block tiers by bimonthly residential consumption, plus a fixed bimonthly meter-service charge. For rates effective October 1, 2026, residential water usage is $8.50 per CCF for 1–8 CCF, $10.06 per CCF for 9–18 CCF, and $12.36 per CCF above 18 CCF; separate non-residential, irrigation, hydrant, and fireline schedules apply. One CCF is 748 gallons.. Bills are generated bimonthly for accounts receiving city water, sewer, and related emergency-services-facility-tax charges; sewer-only accounts are also described by the city as bimonthly., and a typical residential cost reference is For a typical single-family customer using approximately 5,000–7,000 gallons per month (about 6.7–9.4 CCF monthly, or roughly 13.4–18.7 CCF per bimonthly bill), a 3/4-inch meter has a $61.14 bimonthly service charge at the October 1, 2026 rate. Water is therefore approximately $92–$128 per month before taxes or other charges, depending on consumption. Adding the standard residential sewer charge of $53.57 per month effective July 1, 2026 produces an indicative combined water/sewer total of approximately $145–$182 per month; actual bills vary by meter size, property type, usage, and any tax or emergency-facility charges.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
Residential sewer is a fixed monthly amount selected by property type and the amount of metered water used, rather than a separate residential winter-average formula. Effective July 1, 2026, the standard single-family or 2–4-unit residential charge is $53.57 when the unit uses more than 8 CCF; the economy tier for 5–8 CCF is $25.23, and the lifeline tier for 0–4 CCF is $13.01. Multifamily is $48.71 per unit and mobile-home service is $36.23 per unit. Non-residential customers are billed per CCF of metered water based on business classification and wastewater strength; critical users additionally pay flow, carbonaceous biochemical oxygen demand, and suspended-solids components.
Meter and infrastructure notes
Hayward uses smart meters connected to its WaterSmart customer portal. The portal provides hourly usage and leak-alert data, along with daily, weekly, monthly, and annual consumption views and budget notifications; the City’s public materials do not identify the AMI manufacturer or a route-day reading calendar. Water accounts are billed bimonthly, while the smart-meter system provides near-real-time hourly data so customers can identify continuous flow, leaks, unusually high use, and likely high bills between bills.
