Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- 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.
- Rate structure
- 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.
- Residential cost reference
- 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.
- 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 reading
- 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.
- New-account deposit
- To establish new service, the City requires the service address, customer identity and contact details, driver’s-license number, Social Security number or other government ID, a non-refundable $18 account setup fee, and a deposit of $213 or more depending on the residence. The deposit is retained until the account closes, then applied to the final bill; any remaining credit is refunded by check regardless of the original payment method. The reviewed pages do not state a credit-check waiver or an automatic on-time-payment return during an active account.
- Activation or transfer fee
- The 2026 account setup or turn-on fee for potable or recycled water is $18 and is non-refundable. New service and cancellations generally require one business day to process. The City does not publish a separate universal resident-to-resident transfer fee in the reviewed pages; moving customers should contact Utility Billing at (909) 364-2660 and confirm whether the move is treated as a new account, cancellation, or transfer.
