Sewer Lateral and Service Connection Design
Plans for connecting a home or building to public sewer or water, including septic abandonment and long laterals.
What the work involves
Connecting to public sewer or water may require a plan showing lateral routing, cleanouts, pipe slope, tap location and abandonment of an old septic tank or well. Plumbers handle many simple connections, but utilities often ask for engineered plans when laterals are long, deep, cross other property, require a pump, or serve commercial buildings.
Local conditions we plan for
- Deep frost penetration and frost heave
- Expansive clay soils
- Red River spring flooding
- Energy sector growth in the Bakken region
Building code: 2024 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Utility requires connection when sewer becomes available
- Converting from septic to public sewer
- Long, deep or shared lateral
- Commercial service connection or new tap
