East Orange County Water District (EOCWD) – Retail Zone RZ

Provider briefing

How this utility’s billing works

East Orange County Water District (EOCWD) – Retail Zone RZ operates as a public water authority serving East Orange, North Tustin, and portions of unincorporated Orange County; Retail Zone RZ / PWS CA3010068. 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 Budget-based residential allocation combined with fixed and volumetric charges. EOCWD describes a fixed monthly service charge based on meter size, a fixed capital-projects charge, and a volumetric commodity charge per CCF; residential water budgets include an indoor allocation based on 55 gallons per person per day plus an outdoor allocation based on landscape area and evapotranspiration. The published five-year rate schedule identifies a single commodity rate rather than a published multi-tier price ladder. The schedule’s FY 2027 column, effective July 1, 2026, lists a 5/8-inch monthly service fee of $40.72 and a commodity rate of $5.52/CCF, with the capital fee collected through the property-tax roll.. Bills are generated bi-monthly. eocwd’s 2026 rules and regulations state that retail water service charges are billed once every two months, subject to board modification. bills are due 30 days after the billing date, and the rules also require the due date printed for ordinary bills to be no less than 25 days from the billing date., and a typical residential cost reference is Using the published FY 2027 column effective July 1, 2026, 5,000–7,000 gallons is approximately 6.68–9.36 CCF. At $5.52/CCF, the volumetric component is about $36.90–$51.66 per month. Adding the 5/8-inch service fee of $40.72 and the published 5/8-inch capital fee of $64.09 produces a water subtotal of approximately $141.71–$156.47 per month. Adding the FY 2027 single-family sewer charge equivalent of $169.94 annually, or about $14.16 monthly, produces an estimated combined water-plus-sewer monthly equivalent of approximately $155.87–$170.63. The capital charge is collected through the property-tax roll rather than necessarily appearing on the water bill, and the five-year schedule is the District’s published rate plan rather than a usage-specific bill guarantee.. 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

EOCWD bills sewer service annually through the property-tax bill according to property type, not as a percentage or winter average of potable-water intake. The published schedule lists a FY 2027 single-family residential annual sewer charge of $169.94 effective July 2026, and $118.96 per multifamily dwelling unit. Non-residential charges are based on building area and property-use classification factors. Wastewater is collected through EOCWD’s sewer system and conveyed to Orange County Sanitation District for treatment and reuse.

Meter and infrastructure notes

EOCWD’s current project page says the District is soliciting proposals for an upcoming Advanced Metering Infrastructure project, so a fully deployed AMI network and specific vendor cannot be confirmed from the current public record. The 2026 rules state that bills are based on meter readings or, in some cases, estimated usage; customers may request a second reading and may request a meter-accuracy test. A meter found to register 3% or more above actual flow is replaced and can generate a refund for verified prior-period overcharges. The public materials do not publish a universal monthly read calendar or interval-transmission schedule for the existing meters.
