Pewaukee has some of the hardest municipal water in Waukesha County. Not “slightly elevated” hard. Genuinely hard.
The City of Pewaukee reports hardness between 338 and 345 parts per million across its east and west water systems. That’s roughly 20 grains per gallon,
nearly triple the 7-grain threshold where fixtures start scaling up.
Schoenwalder Plumbing has served Pewaukee since 1945.
Our Waukesha shop is a 10-minute drive from downtown Pewaukee, and we offer same-day and next-day appointments for most service calls. We handle everything
from water softener installation to full bathroom remodels. Our licensed plumbers carry the parts and diagnostic tools to fix most issues on the first visit.

Pewaukee’s groundwater comes from wells drilled into limestone and sandstone, two formations loaded with calcium and magnesium.
Both the City and the Village of Pewaukee draw from these aquifer sources. Both systems produce water that’s naturally high in dissolved minerals. That’s not unusual for southeast Wisconsin, but Pewaukee’s numbers are at the top end of the county range.
Hard water does real damage over time. Calcium scale coats the inside of water heater tanks, forcing the burner to work harder and driving up gas bills. Showerheads lose pressure. Dishwashers leave white film on glasses. Washing machines need more detergent. After 80 years of working in Pewaukee homes, we’ve pulled water heaters where the scale buildup was over half an inch thick at the bottom of the tank. Those units were only 6 years old.
The Village of Pewaukee has a separate concern. Well 4 in the Village system has tested above the federal limit for combined radium (7.92 to 8.74 pCi/L against a 5.0 pCi/L standard, per the Village’s own disclosure). A radium removal filter is under construction, but homeowners on that system may want point-of-use filtration as an extra layer of protection right now.
We install and service water softeners, iron filters, reverse osmosis drinking water systems, and whole-house filtration for Pewaukee homes on both City and Village water. For properties on private wells, we also provide well water testing, pump maintenance, and chlorination.
Same-day or next-day for routine calls. Our Waukesha shop is about 6 miles from downtown Pewaukee, roughly a 10-minute drive.
Our shop at 1720 Dolphin Drive is about a 10-minute drive from downtown Pewaukee. Most mornings, trucks are dispatched before 8:00 AM. For urgent issues like burst pipes, no hot water, or sewer backups, call (262) 542-7908 and we’ll get a plumber headed your way the same day.
Eighty years of serving Pewaukee means our plumbers know the housing stock here. The older homes near the lake tend to have galvanized steel pipes that corrode faster in hard water. Newer subdivisions west of Highway 16 are mostly PEX and copper. That local knowledge means faster diagnosis and fewer return visits.
Schoenwalder Plumbing covers residential and commercial plumbing across Pewaukee and the wider Lake Country region.
We test your water first. Pewaukee’s municipal supply runs around 20 grains of hardness, but well water in the area can test even higher depending on well depth and geology. We size the system to your household’s actual daily usage, not a generic estimate. We install water softeners, iron filters, reverse osmosis drinking water systems, and UV disinfection units for homes on well water.
A 50-gallon gas water heater typically lasts 8 to 12 years. Hard water shortens that. If your unit is over 8 years old and you’re noticing longer recovery times or rusty water at the tap, it’s time for an inspection. We install and service both conventional tank and tankless water heaters from Rheem, A.O. Smith, and Rinnai. Our plumbers are certified installers for all three brands.
Here’s something most homeowners don’t realize: slow drains in Pewaukee are often caused by mineral scale from hard water, not food or grease. We use video sewer inspection cameras to see exactly what’s happening inside your pipes before we recommend anything. That saves you money and prevents unnecessary drain cleaning work.
Properties outside the City and Village water systems rely on private wells. Submersible pumps typically last about 15 years with proper maintenance, but hard water and sediment wear them down faster. We’re licensed pump installers (State of Wisconsin DNR Certified PI #7661) and members of the Wisconsin Water Well Association and the National Ground Water Association. If your well pump is cycling on and off or your water pressure drops when two taps run at once, those are the early warning signs.
Plumbing work is the foundation of any remodel. We handle the full scope, from rough-in plumbing for new layouts to fixture installation and finish work. That goes for bathrooms and kitchen remodels alike. Visit our Bath and Kitchen Showroom at 1720 Dolphin Drive in Waukesha to see working product displays before you commit to a design.
Pewaukee requires annual backflow preventer testing for commercial properties and irrigation systems connected to the municipal supply. Our team includes Cross Connection Control certified testers who handle the inspection, certification, and any repairs needed to pass.

Pewaukee’s water comes from groundwater wells drilled into limestone and sandstone formations. The City of Pewaukee reports hardness between 338 and 345 parts per million, which is roughly 20 grains per gallon. That level causes scale buildup in pipes, water heaters, and fixtures. A properly sized water softener solves the problem.
