Excavation and Septic Work in New Haven, MO

New Haven is a Franklin County river town on the south bank of the Missouri River, west of Washington along Highway 100. We serve New Haven and the farms and rural homes around it with excavation, drainage and septic work.

Ground conditions around New Haven

New Haven combines Missouri River bottomland with steep bluffs and hills just south of the river. Bottomland soils and a higher water table call for careful drainage and septic planning, while bluff and hillside lots bring slope, rock and erosion concerns. Matching the excavation plan to the ground is the difference between a site that stays dry and one that fights water every spring.

Permits and planning in Franklin County

Properties inside New Haven city limits may follow city rules and connect to city sewer. Rural properties outside town are generally in unincorporated Franklin County, where new and replacement septic systems require a county sewer permit, typically with soil or percolation testing first. Lots near the river may also have floodplain considerations. On New Haven sites, buried utilities are located through Missouri 811 first.

Projects we handle in New Haven

New Haven projects include basement and foundation digs, erosion control on hillsides, grading and drainage for yards and driveways, retaining walls, utility trenching and septic systems for homes outside the city sewer area.
