What shapes water heater trouble in Weiser
Two rivers, one plant
Weiser's water comes from both the Weiser and Snake rivers and is treated at the city's plant on Mortimers Island with coagulation, settling, filtration and chlorine. The 2025 report says lead wasn't detected at consumer taps and copper came in at 0.049 ppm. It doesn't give a hardness figure.
That report also lists one violation: total trihalomethanes, a chlorination by-product, reached 96.8 ppb against an 80 ppb limit. The city says it told customers at the time. Questions go to the water department at 208-414-1775.
Old homes, old service lines
The median Weiser home was built in 1971, and about 29% are older than 1940. Only about 13% date from 2000 or later, and about 13% are mobile homes. About 37% of households rent. Gas heats about 55% of homes and electricity about 38%.
The city's service line inventory includes lead lines, and it says some homes and pipes in town are over a century old, so lines without records are classed as unknown until confirmed. If your home was built before 1988, the city asks you to fill out its service line questionnaire. NOAA's Weiser station averages about 136 freezing nights a year.
State plumbing permits, county drop-off

The city runs its own garbage pickup, and everything picked up must be inside the can. Washington County's Weiser Transfer Site, at Hwy 95 and Transfer Site Rd., is open Monday to Saturday, 8:30 to 4:45. Call 208-549-1284 to ask about taking an old tank.
