- Source
- Chino Hills' water is a mix of groundwater from City-owned wells, Monte Vista Water District wells and Chino Basin Desalter Authority wells, and State Water Project surface water bought through the Water Facilities Authority and Monte Vista Water District.
- Lead
- In the City's latest lead sampling (2024), the 90th percentile was 0 ppb and none of the 30 sites exceeded the action level; the City's service line inventory found no lead lines.
Sewer
The City bills about 20,800 customers each month for sewer service. The FY 2026-27 residential charge is $29.45 a month for IEUA treatment plus $17.80 for the City's operation and maintenance fee; pumped-flow areas also pay a City pumping fee ($2.48 per EDU in FY 2027).
Ways to pay less
- Low income: water bill discount (LIRA). The City's Low-Income Rate Assistance program takes $10 off the monthly water meter charge for 12 monthly bills. You must live at the home, have a meter of 1 inch or smaller, have the account in your name and show you are enrolled in SCE or SoCalGas CARE. A new application is required every year. How: Apply online, by mail or at the Utility Billing counter at City Hall, 14000 City Center Drive.
