Best Companies in Milwaukee, WI

A trusted provider for well and septic inspections across southeastern Wisconsin counties.

Area Septic Installation (ASI) is a full-service septic and grinder pump contractor serving Southern Wisconsin and Northeast Illinois from their base in Nashotah, WI. Founded in 2008, they specialize in grinder pump repair, maintenance, installation, and inspection for both residential and commercial customers across Milwaukee, Waukesha, Racine, and Kenosha counties and beyond. ASI sets itself apart by focusing specifically on grinder pump and sewer pump systems — the pressurized pump systems used in low-pressure sewer networks common in Wisconsin subdivisions. Their certified technicians carry factory replacement parts for all major brands, enabling same-day repairs in many cases. Emergency service is a core offering — customers with a sounding septic alarm are directed to call immediately. They serve over 25 municipalities including Milwaukee, Madison, Waukesha, Racine, Oshkosh, Grayslake, and Pleasant Prairie. Both homeowners and commercial property managers use ASI for annual inspections, preventive maintenance agreements, and emergency callouts. With nearly two decades of focused experience in the grinder pump niche, ASI is well-positioned for Wisconsin markets where municipal sewer systems use low-pressure mains requiring individual property pump systems. Not a full septic tank pumping company — their core competency is the pump and alarm side of the system.

Now operating for over 60 years, Badger Labs is certified by both the Wisconsin DNR and DATCP, making it one of the state's most credentialed analytical labs. The company operates from three locations: Neenah, Green Bay, and Stevens Point — with no Milwaukee office, though the Milwaukee metro is a short drive from their Neenah headquarters. Badger Labs provides analytical testing services for drinking water, groundwater, wastewater, sludge, soil, and waste streams. Their client base ranges from private homeowners getting private well water tested, to Fortune 500 industrial clients managing environmental compliance. They also offer field sampling and monitoring services, environmental consulting, and hemp/CBD testing. This entity is flagged as a misclassification for the well/septic contractor database. Badger Laboratories is a certified analytical testing laboratory — their business is water quality and environmental sample analysis, not well drilling, pump installation, or septic system construction and maintenance. The Milwaukee city association in the database may reflect a service area rather than an actual Milwaukee office.
