Most of Upland's water is local groundwater from city and partner wells, and groundwater in this region tends to carry hardness minerals. A softener can cut down on scale in fixtures and water heaters once you know your hardness level. Call the number on this page to be connected with a local plumber in Upland.

Is it hard water? Common signs
- Chalky deposits around faucet handles and drains
- Glass shower doors that never look clean
- Low flow from showerheads as openings close up
- Crusted ice maker lines or dispenser nozzles
- A water heater that rumbles or takes longer to recover
Where Upland's water comes from
The City of Upland's Public Works Department provides water service. Local groundwater meets about 80 percent of customer needs, drawn from City wells and from San Antonio Water Company and West End Consolidated Water Company wells in the Chino, Cucamonga and Six Basins. The rest is San Antonio Canyon surface water, treated at the city's canyon treatment plant, and imported State Water Project water treated at the Water Facilities Authority plant.
This page does not quote a hardness figure for Upland. The city's annual Consumer Confidence Report includes the numbers. Because the supply blends several sources, a test at your own tap is the most reliable way to size equipment.
Upland's inventory of water service lines focused on homes built before 1987. If your home is that age, the plumber may suggest checking the piping near the main before tying in new equipment. Corroded fittings at the tie-in are easier to replace while the water is already shut off than to chase later as a slow leak behind the garage wall.
What affects the cost
- Hardness and household water use, which determine unit capacity
- Where the main line can be cut in, and how much pipe is needed
- Access to a drain and a power outlet
- Condition of older valves and pipe near the main
- Optional carbon filtration or an under-sink drinking water system
- Salt or potassium over time
When you call
We connect you with an independent plumber who works in Upland. Mention what you have noticed, roughly how old the house and water heater are, and whether the garage has a laundry standpipe nearby that could take the drain line. Upland's Building and Safety Division accepts permit requests online through its Citizen Self Service portal, and the plumber can check whether your installation needs one. For a leak on the City's side of the meter, Upland Public Works is the contact at (909) 291-2930.
