The City of Chino operates the public sewer system, along with water and storm drains. When the private sewer line from your house clogs, breaks or fills with roots, a plumber handles the repair. Call the number on this page to be connected with a local plumber in Chino.

Sewer service in Chino
Chino keeps its utilities in house: the City operates the water, sewer and storm drain systems, and its Utility Billing Services Division handles accounts. That makes the public side easy to reach. For a sewer problem in the street during business hours, call Utilities customer service at 909-334-3264. After hours, the City says to call the Chino Police Dispatch Center at 909-628-1234 so City personnel can respond.
Housing age varies across Chino, so what is under your yard differs from one lot to the next. In practice, plumbers here find everything from older rigid pipe to recent plastic lines, and the right repair depends on what the camera shows. Like most Inland Empire homes, Chino houses are slab-on-grade, so the building drain runs beneath the floor before it reaches the lateral outside.
Permits are a real consideration. The City of Chino Building Division says nearly all construction or repair work needs a permit, with minor items such as fixing a leaky faucet exempt. Sewer pipe replacement is permitted work.
Choosing a repair
| Finding on camera | Typical fix | Notes |
|---|---|---|
| Grease or soft blockage | Cable or jetting | No pipe replaced |
| Roots at one joint | Clear, then spot repair or line | Clearing alone buys time only |
| Crack or offset joint near the house | Spot excavation | Permit usually required |
| Long run of broken or sagging pipe | Lining, bursting or new pipe | Larger project with inspection |
Signs to watch for
- A floor-level drain backs up first
- Toilets bubble when other fixtures drain
- A sewage smell outside near the cleanout
- Clogs return soon after being cleared
Timing and seasons
Winter storms put extra water into the ground and the system, which is often when a weak lateral finally backs up. Summer heat sends roots after any moisture leaking from a joint. Book a camera inspection during dry weather if your line has needed attention more than once, and ask the plumber to note depth and location so a repair can be planned without a rush. Keep new trees away from the path of the lateral. The Building Division is at 13220 Central Avenue, (909) 334-3251.
