Where Old Claremont sits.
Old Claremont is the residential side of the Claremont Village area, a few blocks north of the downtown shops. Local real-estate guides place North Indian Hill Boulevard through it, Memorial Park on its east side, the Claremont Colleges a few blocks east and the Foothill Boulevard corridor, the old Route 66, along the north. Oxford Avenue and Cambridge Avenue are two of its named streets.
No one publishes a formal boundary line for the area, so treat those streets as landmarks rather than borders. If you live near them, this page is for you. The phone line covers every street in Claremont, and the same plumbers handle all of it.
Mixed eras, big lots, mature trees.
Listing-site guides describe the homes here as a mix of midcentury ranch and modern houses alongside Spanish Revival, Craftsman and Tudor-inspired homes, mostly on large grassy lots with mature trees. One guide puts the typical year built near 1948. That is a general picture, not a survey of your block, and it says nothing about what pipe is in any one house.
What it means in practice: a street with big trees and houses from different decades is a good place to learn what your sewer lateral looks like before it fails. A sewer camera inspection shows the real pipe, whatever the house's age. If a drain keeps slowing down, drain cleaning clears it, and the camera tells you why it keeps coming back.
Calls that come from a neighborhood like this.
- A tub or shower draining slowly while a toilet gurgles, which points toward the main drain.
- A sewage smell near a cleanout or in the yard.
- A water stain under a kitchen or bathroom after the faucet has run.
- Rust or water at the base of a tank water heater.
- A water meter that keeps moving with every tap shut off.
- Weak flow at one fixture while the rest of the house is normal.
Which pipe belongs to whom.
Golden State Water Company maintains the lines up to your water meter. A leak past the meter is the property owner's to fix. The City of Claremont owns and operates the sanitary sewer, and the main usually runs under the middle of the street. The private lateral between your house and that main is yours.
The City does not respond to problems inside a private lateral, and it asks that you confirm with a plumber that the lateral is the problem before you call. If you need to reach the City about a backup, Community Services is at (909) 399-5431 on Monday through Thursday from 7am to 6pm. After hours, the Police Department non-emergency line is (909) 626-1296. The Engineering Division at (909) 399-5465 can help locate the lateral.

Questions homeowners ask.
Old Claremont plumbing questions.
.
Yes. Calls from the residential streets north of the Village, including the Indian Hill Boulevard and Memorial Park area, go to the same line that covers all of Claremont, ZIP 91711. Call and give your street so the plumber knows where to go.
.
Stop running water, keep everyone out of the wet area and call. The City of Claremont says the private lateral is the owner's responsibility, and Community Services at (909) 399-5431 can discuss the City main. A plumber can tell you quickly which side of the cleanout the blockage is on.
.
The property owner. Golden State Water Company maintains the lines up to the meter, and the water company's own advice is to turn off all water and watch the meter needle. If it keeps moving, there is likely a leak on the property side. A leak detection visit finds it.
.
Roots can enter any small gap in a pipe joint, and mature trees are common here, so it is a fair concern. It is not a given for any one house. A camera inspection shows whether roots are present, and then you decide on cleaning or repair with real information.
