The City of Upland's Public Works department supplies water to Upland businesses, mostly from local groundwater, and handles leaks on the City side and City meters. Building permits are requested online through the City's Citizen Self Service portal. Call the number on this page to be connected with a local plumber in Upland.

Warning signs at an Upland business
- Water seeping up near the City meter or the curb
- A restroom block or break room sink that drains slowly every afternoon
- Spotty pressure at the far end of a long building
- Water heater relief valves dripping or tanks rusting at the base
- A sewer smell around a floor drain that rarely gets used
- Kitchen lines needing to be cleared more often than they used to
Upland's water system and permits
About 80 percent of Upland's customer supply is local groundwater pumped from City wells and from San Antonio Water Company and West End Consolidated Water Company wells in the Chino, Cucamonga and Six Basins. San Antonio Canyon surface water is treated at the San Antonio Canyon plant, and imported State Water Project water arrives through MWD and IEUA after treatment at the Water Facilities Authority plant. The City's annual water quality report lists current mineral and treatment data for anyone sizing a softener or filter for commercial equipment.
Public Works handles City-side water leaks and maintains City meters; report service requests and leaks to (909) 291-2930. After hours, mainline leak emergencies go to Upland Police Dispatch at (909) 946-7624. The City's pages mention sewer service charges and a sewer backup procedure but don't spell out who maintains which part of a lateral, so ask the City before work at the connection. The Utilities Division completed a service line inventory under EPA lead rules, focused on homes built before 1987, and posts the report on its water quality page.
Permits come from the Building and Safety Division at 460 N. Euclid Avenue. Requests are accepted online only through the Citizen Self Service portal, and the permit technician line is (909) 931-4110, option 1. Commercial backflow testing requirements in Upland vary by connection, so confirm with Public Works whether a fire, irrigation or process connection needs an assembly.
Factors that set the price
- How much of the building is affected and how many fixtures share the line
- Access through hard ceilings, slab floors or parking lots
- Whether the work has to happen before opening or after closing
- Equipment size and venting for commercial water heaters
- Permit and inspection steps
Calling for help
An independent local plumber who handles commercial work in Upland will want the address, the type of business and what's going wrong. Know where the building's main shutoff is before you call, and have a recent water bill nearby in case the meter readings matter.
