Plumbers in Upland, CA

A foothill city at the west end of the valley

Upland sits below the San Gabriel Mountains in San Bernardino County, about 19 miles northwest of Riverside in a straight line, between Montclair and Rancho Cucamonga. It had 79,040 residents in the 2020 Census.

City water with a local base

The City of Upland provides water through its Public Works department and Utilities Division. Local groundwater covers about 80 percent of customer needs, pumped from City wells and from wells of the San Antonio Water Company and the West End Consolidated Water Company in the Chino, Cucamonga and Six Basins. San Antonio Canyon surface water is treated at the City's San Antonio Canyon Water Treatment Plant, and imported State Water Project water arrives through MWD and IEUA after treatment at the Water Facilities Authority plant. The City publishes its consumer confidence report on its Water Quality page; no hardness figure was recorded for this page, so check that report before choosing a softener.

The City handles leaks on its own side of the system and maintains City water meters. The exact point where the customer's line begins is not spelled out on the City page, so if a leak shows up near the meter, call Public Works first at (909) 291-2930 to see whose it is. After hours, mainline leak emergencies go to Upland Police Dispatch at (909) 946-7624.

Lead line inventory and older homes

Upland's Utilities Division ran a water service line inventory under federal lead rules, focused on homes built before 1987, and posts the inventory report on its Water Quality page. Homeowners in older houses can check that report for their address. No overall housing-age figure was gathered for this page. In any house that has been around a while, a plumber may find galvanized supply piping or aging drain lines worth inspecting during other work.

Sewer, weather and slabs

Sewer service details were not confirmed in the research for this page, so check your utility bill for the agency before reporting a public sewer problem. Being closer to the mountains, Upland can see colder winter nights than the valley floor, which makes insulating hose bibs and exposed pipes worthwhile. Most homes are on slabs, so a hot spot on the floor or a meter that spins with every tap closed may point to a slab leak.

Permits and gas

The Building and Safety Division, 460 N. Euclid Avenue, accepts building permit requests online only through the Citizen Self Service portal; the permit technician line is (909) 931-4110, option 1. SoCalGas serves Upland. If you smell gas, leave right away, and from a safe place call 911 and SoCalGas at 1-800-427-2200.

Upland vs. Riverside, and calling

Both cities lean on local groundwater, but Upland mixes in canyon surface water and has its own City utility and online-only permits. When you call the number on this page, explain the problem, and you will be connected with an independent plumber who covers Upland. Price and timing are between you and that plumber.
