Provider briefing
How this utility’s billing works
City of Fullerton Public Works Water Division and Utility Services Division operates as a municipal department serving City of Fullerton. 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 Fixed monthly meter charge plus an increasing three-tier residential usage charge. For bi-monthly customers, the monthly tier allocations are doubled for the billing period; non-residential customers use a uniform rate rather than residential tiers. The City’s current rate-study materials explain that fixed charges support system operations and capital reinvestment while usage charges reflect groundwater, imported water, and pumping costs.. Bills are generated residential accounts are generally billed bi-monthly, with six bills per year; fullerton also has monthly billing cycles for some accounts. the city’s recent billing-system transition temporarily altered the number and spacing of bills in 2024-2025, so the individual account statement controls., and a typical residential cost reference is A dedicated this detail was not publicly posted. An exact current 2026 5,000-to-7,000-gallon residential estimate could not be calculated from the live City pages because the linked water-rate schedule was not retrievable in the current review. Fullerton’s current pages confirm the fixed-plus-three-tier mechanics, but the applicable 2026 meter charge, tier allocations, commodity rates, and any current sewer rate must be read from the account’s official rate schedule.. 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
Fullerton’s Sewer Service Fee is based on each resident’s or business’s actual water usage and is placed in the Sewer Enterprise Fund for sewer operations, regulatory compliance, capital improvements, and replacement. The standard residential sewer fee uses 40% of measured water use; a qualifying property of at least one-half acre may apply for a large-lot rate using 20% of water use. The residential life-line rate is currently unavailable until further notice.
Meter and infrastructure notes
Fullerton bills from previous and current meter-read dates, with residential accounts commonly billed bi-monthly and some accounts monthly. The City provides meter-accuracy testing, water-use history, and online account access, but the current public materials do not identify an AMI/AMR vendor, interval-transmission capability, or a complete route-by-route reading calendar. The public documentation therefore supports metered service and account-level consumption history, not a confirmed smart-meter deployment.
Emergency water support
Report a leak or water emergency
Fullerton’s after-hours emergency contact for water, sewer, streets, traffic, storm drains, or parks is (714) 738-6897. During service hours, the Water Division uses the same number for meter leaks, street breaks, water-connection problems, and urgent water-quality or pressure issues; call 911 for police, fire, paramedic, or life-safety emergencies.
