Provider briefing
How this utility’s billing works
California Water Service Company - Marysville System operates as a private investor-owned utility serving Marysville service area within Yuba County, primarily the levee-protected City of Marysville area. 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 CPUC-regulated metered residential structure for the Marysville tariff area, with a fixed monthly service charge plus volumetric charges under the Residential Metered Service MRL schedule; separate non-residential schedules apply. Cal Water's current Marysville page identifies Residential Metered Service MRL as effective July 1, 2026, but the live page did not expose the current dollar table during review, so unpublished tier amounts are not inferred.. Bills are generated generally monthly billing, with the bill showing the service period, meter read dates, current charges, due date, and prior balance. the exact read and due-date calendar is premise-specific., and a typical residential cost reference is A dedicated this detail was not publicly posted. For an exact 2026 dollar estimate because Cal Water's current Marysville page confirms the July 1, 2026 residential-metered tariff but its live rate link did not expose the current dollar values. Cal Water's 2026 infrastructure page identifies median use as 4,488 gallons, or 6 CCF, and reports a three-cent-per-day bill increase under the new rate decision, but that is not a complete bill amount. Sewer, taxes, surcharges, and city charges are excluded.. 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
Cal Water bills the Marysville potable-water charge. Sewer or wastewater charges are normally imposed separately by the City of Marysville or another serving sewer agency and are not governed by one Cal Water formula. The sewer agency may use actual water consumption, a winter average, a residential cap, or a fixed equivalent-unit charge. Customers should compare the water meter usage with the separate sewer bill and ask the serving agency for its current base, usage, winter-average, and adjustment rules.
Meter and infrastructure notes
The Marysville system uses customer water meters and Cal Water's periodic billing reads. The district page does not publish a fixed local AMI deployment percentage or route day; Cal Water company materials describe AMR/AMI pilots in selected districts but do not establish that every Marysville account has an advanced meter. Customers should use the bill's read dates and current/previous reads, review usage history in the portal, and ask Cal Water to confirm the exact meter technology and leak-alert capability for the premise. Cal Water reports eight active wells, up to six million gallons per day, 55 miles of pipeline, two storage tanks, and three booster pumps.
