The City of Chino operates its own water, sewer and storm drain systems, and its Building Division says nearly all construction or repair work needs a permit. Plumber Riverside CA is a referral line, not a plumbing contractor. Call the number on this page to be connected with a local plumber in Chino.

Plumbing services in Chino
West of Riverside in the Chino Valley
Chino is in the southwest corner of San Bernardino County, about 17 miles west of Riverside in a straight line, with Chino Hills on one side and Ontario on the other. It had 91,403 residents in the 2020 Census.
One city for water and sewer
The City of Chino runs the water system, the sewer system and the storm drains, and its Utility Billing Services Division handles accounts. For billing or service questions during the day, call utilities customer service at 909-334-3264. After regular hours, the City asks residents to report water or sewer emergencies through the Chino Police Dispatch Center at 909-628-1234 so City crews can respond. That is the number for a broken main or a backup in the public sewer, not a leak inside your house.
The City posts its annual water quality report on its Water Quality Report page. That report lists Chino's water sources, hardness and disinfectant, so read it directly before buying a softener or filter. As a general Inland Empire pattern, hard water and mineral scale are common.
Permits for almost everything
The Development Services Department's Building Division, 13220 Central Avenue, (909) 334-3251, issues permits. Its own FAQ says nearly all construction or repair work requires a permit, and repairing a leaky faucet is one of the few listed exceptions. Plan on a permit for a water heater swap, a repipe, a new gas line or a sewer line repair. Fee tables are available at the counter.
What to know about your home's plumbing
Housing age varies across Chino, so typical pipe materials differ from one neighborhood to the next. A few general points still help:
- Find your main shutoff before you need it. In most slab homes it is near where the supply line enters the house.
- Water heaters should be strapped, since California is earthquake country, and a tank that is rusting at the base or leaking from the bottom should be replaced rather than patched.
- If a drain backs up in the lowest fixture first, the blockage is likely in the main line rather than one sink.
- Hot summers and Santa Ana winds are hard on exposed irrigation piping and backflow assemblies.
Gas safety
The City of Chino says SoCalGas is the natural gas provider for residents and businesses in the city. If you smell gas, leave the house first, then call 911 and SoCalGas at 800-427-2200 once you are safely outside.
How Chino differs from Riverside, and calling
Riverside splits water and sewer between Riverside Public Utilities and the city's Public Works; in Chino one city government handles both, and its after-hours line goes through the police dispatcher. When you call the number on this page, say what is happening and whether the water is shut off, and you will be connected with an independent plumber who serves Chino. Pricing and the appointment are set between you and the plumber.
