Every pipe on the site
Trinity Earthworks installs the underground utilities that every commercial building needs: storm drainage to carry rain off the site, sanitary sewer to the public system, and water and fire lines to the building.
Our owner is a licensed Tennessee general contractor with the municipal-utility (MU) endorsement, and our crews have made tie-ins everywhere from open lots to the middle of Broadway at night.

Because we also run our own pipe camera and jetting equipment, we can clean and televise the storm and sanitary lines we install before the city or engineer inspects them.
