Construction Contractor in the Water and Wastewater Industry

Our company was established in 1945 by Joe, Charlie, and Bill Dunigan. We began as a small contractor in the Jackson, MI area. Since then, we have grown into one of the premier water and wastewater contractors in Southern Michigan, Northern Ohio, and Indiana.

Today, Joe’s sons—along with some of their own sons—are still actively involved in the daily operation and management of the business. For more than 70 years, we have been building projects, providing underground and other construction services throughout our working territory. Some of the work we have completed over the years include:

  • Underground Water and Wastewater Piping Systems
  • Treatment Plants
  • Pumping and Pressure Stations
  • Site Development
  • Building Demolitions
  • Highway/Roadway Construction
  • Mass Earthmoving Projects
  • Providing Lifting Crane Services
  • Sheeting and Shoring Projects

Our Company Today

The second and third generations of the Dunigan family have narrowed the focus from the broad range of heavy civil construction provided throughout the mid to late 1900’s. While we still provide street construction and site work services, our primary focus now is on underground sewer and water construction services. These include pressure water and sewer piping, gravity sewers, and pumping station construction.

Our extensive experience and knowledge of the underground construction industry have allowed us to become one of the leading underground contractors. We have completed some of the most complicated projects from water transmission mains, water distribution systems, combined sewer separation projects, and complete new gravity sewer systems.
