Why Hillsboro homes need these repairs

Hillsboro is the Silicon Forest suburb west of Portland, with an older downtown and many 1990s–2010s subdivisions and apartments. Its water comes mainly from the upper Tualatin River through the Joint Water Commission, with Willamette River water coming online, and wet winters drive drainage and crawlspace calls.

Hillsboro's water supply and your plumbing

Hillsboro's primary water source is the upper Tualatin River, treated at the Joint Water Commission plant at Fern Hill, Oregon's largest conventional treatment plant at up to 85 million gallons a day. [1]

In summer, Barney Reservoir and Hagg Lake (Scoggins Reservoir) supplement supply, and Hillsboro is developing the Willamette River at Wilsonville as an additional source with TVWD and Beaverton. [2]

Hillsboro plumbing questions

When is a leaking water heater an emergency in Hillsboro?

A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Hillsboro: Tanks in 1990s–2000s homes reach end of life.

Can recurring clogs in Hillsboro mean a sewer line problem?

Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Hillsboro: Older laterals near downtown crack and take in roots.

Where does Hillsboro's water come from?

Mainly the upper Tualatin River, treated by the Joint Water Commission, with summer help from Barney Reservoir and Hagg Lake.

Will Hillsboro water change when Willamette water arrives?

Taste and hardness may shift slightly as the city blends the new Willamette supply; both sources are treated to the same standards.

Is Hillsboro water hard?

No, Tualatin River water is soft, so scale is rarely a problem.

Why does my Hillsboro crawlspace flood in winter?

Heavy rain raises groundwater. Footing drains and a sump keep water off pipes and insulation.
