Plumbing in Santa Clara
A city with its own water
Santa Clara is one of the few cities in the valley that pumps most of its own water. That keeps the supply local, but well water carries more dissolved minerals than imported water, and those minerals end up as scale inside tank heaters, tankless heat exchangers and fixtures.
Because the city borders San Jose, Santa Clara calls are scheduled from the same office and the same trucks. Water heaters, fixture replacements, drains and leak repairs make up most of the work here.
Water and pipes
What Santa Clara's water means for your pipes
The City of Santa Clara runs its own water utility. About 61 percent of the supply comes from 26 city wells, with 20 percent from SFPUC and 19 percent from Valley Water, delivered through 335 miles of mains. SFPUC water mainly serves the area north of Highway 101. If you live south of the freeway, your water is more likely to be well water, and your water heater will scale faster.
Houses and pipes
Older blocks and newer tracts
Santa Clara's older blocks near the university and the original town center have the pipe materials of their time, including galvanized supply lines that narrow with rust and clay laterals that roots can enter. We camera the line before recommending any sewer repair.
The newer tracts and condominiums have plastic or copper supply lines and fewer root problems, so the calls there are mostly water heaters, fixtures and the occasional slab leak.
