Emergency Plumber Highland CA Near Loma Linda

East Valley Water District serves both your water and your sewer

Emergency dispatch for Highland runs around the clock, nights, weekends and holidays. The base is in Loma Linda, and Highland sits about 6 miles northeast of it by straight line. A licensed plumber takes the call, and you hear a clear price before any work starts.

The city's Public Works page sends water and sewer questions to East Valley Water District at (909) 889-9501. The district says it serves about 108,000 people in Highland and parts of San Bernardino across 30.1 square miles. Its 2025 water quality report lists the same number for after-hours emergencies.

The district's leak page warns that a leak on your own property may be your responsibility. In practice, trouble in the street or at the main is the district's call, and trouble inside the house or yard is a plumber's. The sources we read do not say exactly where the private sewer lateral begins, so ask the district before you dig.

Where Highland's water comes from

East Valley Water District's report for 2025 says 78 percent of the supply came from 12 wells in the Bunker Hill Basin. The other 22 percent was surface water from the State Water Project and the Santa Ana River. Disinfection is by chlorine, with an average residual of 0.69 ppm.

The same report gives total hardness averaging 152 ppm, with no grains per gallon figure. Scale builds up in tank bottoms and faucet aerators wherever water carries minerals, so a tank that rumbles or heats slowly deserves a look. That is why water heater repair leads the list below. Test your tap before you spend money on a softener.

From your drain to the Sterling plant

The district also treats wastewater, about 8 million gallons a day according to its home page. Its Sterling Natural Resource Center treats up to 8 million gallons a day and recharges the Bunker Hill Basin with the treated water. The plant is at 25318 5th Street in San Bernardino, not in Highland.

For a homeowner, the plant matters less than the pipe leading to it. A backup in several drains at once calls for a district check of the main and, if that is clear, a camera look at the lateral under sewer line repair. A single slow tub or kitchen sink is usually a branch-line clog that drain cleaning handles.

Which problems Highland calls usually bring, and who to ring first

A moving meter with every tap off is the clearest sign of a hidden leak. Leak detection finds it with acoustic and moisture tools before anyone cuts drywall.

What Highland says about permits

The city's permits page lists plumbing systems as work that needs a permit. Its exceptions page says no permit is needed to clear clogs or to fix leaks in pipes, valves and fixtures. Swapping a toilet, sink, disposal or dishwasher is also exempt if no valves, pipes or fixtures are replaced or moved.

Replacing a failed hidden trap, drain or vent with new material counts as new work and needs a permit. The city pages do not address water heaters or sewer work, so call Building and Safety at (909) 864-6861, extension 232. California also requires a contractor license on any project that needs a building permit, so check the license on the CSLB lookup.

Palm Avenue, Base Line and the Racadio library

Highland was incorporated in 1987, and the 2020 Census counted 56,999 residents on 18.57 square miles. The Highland Historic District on Palm Avenue holds the original townsite, classified in 1891, and its packing houses. If your building is in that older core, say so on the call, because pipe material there may differ from the newer streets.

City Hall is at 27215 Base Line. The Highland Sam J. Racadio Library and Environmental Learning Center is at 7863 Central Avenue. Other roads named in the city profile include Greenspot Road, Sterling Avenue, Boulder Avenue, Highland Avenue and 5th Street, plus SR-210 and I-10. The city also names East Highlands Ranch as a master-planned community, which is useful context only if you know your builder.

Where in Highland we work
