Family-Owned. Rooted in Experience. Built on Trust.

Based in Superior, Wisconsin, Great Lakes Pipe Service, Inc. is a family-owned and operated business specializing in municipal and commercial sewer system cleaning and inspection.

With roots in the sewer industry dating back to the 1970s, our company was built on decades of hands-on experience, a commitment to innovation, and dedication to helping customers keep their wastewater systems operating reliably.

Today, Dave Sigfrids leads the company with the same values that shaped its beginnings: hard work, honesty, and dependable service.

Our story

Dave’s career in the sewer industry began in the late 1970s when he joined the City of Superior’s sewer department.

In 2000, Dave took a leap of faith and started his own sewer cleaning business. Beginning with a used sewer truck and a determination to build something of his own, he began introducing Great Lakes Pipe Service to municipalities throughout the region.

Through hard work, personal relationships, and a commitment to providing quality service, the business grew from its humble beginnings into a trusted sewer cleaning and inspection company.

As a family-owned and operated company, Great Lakes Pipe Service takes pride in the relationships we build with our customers.

Dave’s son, Dylan, is part of the team and handles much of the company’s day-to-day operations. Together, they combine generations of experience with modern technology to provide specialized sewer cleaning and inspection services.

We believe that a strong reputation is built through honesty, reliability, and keeping your word. Those values continue to guide our work everyday.
