Provider briefing
How this utility’s billing works
City of Chino Hills Utility Billing and Water Customer Service operates as a municipal department serving Chino Hills. 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 increasing block tiers with a fixed monthly meter service charge. Current rates shown by the City for 2026 are $3.05 per CCF for Tier 1 indoor budget, $4.20 per CCF for Tier 2 outdoor budget, and $4.51 per CCF for Tier 3 inefficient use; one CCF is 748 gallons. Individual household budgets combine indoor and outdoor allocations and are intended to reflect household size, landscape, weather, and efficient use. Elevation surcharges may apply in intermediate or high zones, and recycled water has a separate $2.70-per-CCF rate.. Bills are generated monthly. the city’s sb 998 policy says water bills are rendered monthly, and the customer-service page states that water meters are read monthly., and a typical residential cost reference is Approximately $90–$105 per month for a typical 5,000–7,000-gallon single-family customer before trash and any elevation surcharge, using the current 5/8-inch $30.10 monthly water service charge, the published budget-based consumption tiers, and FY 2026 gravity-flow sewer charges. The actual total depends on the property’s individualized water budget, meter size, elevation zone, sewer-flow classification, and whether usage crosses the Tier 2 threshold.. 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
Chino Hills combines water and sewer on one monthly utility bill. Sewer charges are based on Inland Empire Utilities Agency treatment costs plus City operation and maintenance, with the residential charge structured as a monthly equivalent-dwelling-unit amount rather than a published winter-average formula. For FY 2026, the published gravity-flow sewer charge is $41.26 per EDU per month ($14.24 City operation and maintenance plus $27.02 IEUA treatment); pumped-flow service is $43.24 per EDU per month because it adds a $1.98 pumping component. Commercial sewer treatment converts water consumption into EDUs using IEUA engineering factors. The City’s FAQ describes the residential sewer component as a flat service charge based on elevation and gravity versus pumped flow, while water consumption is separately metered and tiered.
Meter and infrastructure notes
Water meters are read monthly according to a route-reading schedule, and the City asks customers to keep meter boxes accessible to field readers. The Paymentus portal provides online account and bill information, but the reviewed official pages do not specify an AMI radio model, hourly transmission interval, or smart-meter brand. The defensible 2026 description is municipal monthly metered reading supported by online billing and customer-requested re-reads for suspected reading errors, malfunctions, or leaks.
