Underground Utility Contractor in Madison, WI

Madison is the largest city in Dane County, with an estimated 285,300 residents (2024 Census estimate) on about 84 square miles of land.

Public buildings, campuses and neighborhoods

In a city with many public and institutional buildings, underground work often happens on property with its own procedures: offices, schools, hospitals and campuses with private networks of water, sewer, storm and conduit between buildings, maintained by their own staff.

Work for such owners usually involves:

• their utility drawings and specifications, reviewed together with the Diggers Hotline marks;
• confirmation of private lines with hydro excavation at tie-ins and crossings;
• shutoffs scheduled so that buildings stay in service;
• directional drilling beneath walks and drives that must stay open;
• restoration to the owner's standard, inspected by the owner.

In residential neighborhoods, the jobs are smaller and more personal: a water service, a sewer lateral, a storm connection or conduit to a new garage. They follow the same steps, with care for the yard and the trees above the line.

We also install new services and site utilities for commercial owners and developers.

In Madison, we work for public and institutional owners, businesses, developers and homeowners.
