What Backwell Handles in Fulton

Backwell installs new septic systems and replaces failed systems across Fulton, NY and the rest of Oswego County. Every install is built to NYS Department of Health Appendix 75-A standards and inspected by the local health department before backfill.

Septic Pricing in Fulton

Most Fulton installs land between $8,000 and $28,000 all in. The driver is your soil, not your house size. A well-perc'd sandy site gets a conventional gravity system at the bottom of that range. A clay-bound lakefront lot gets an engineered mound at the top.

Until we run the perc test, anyone quoting you a hard number is guessing. Our process: free site walk, perc test, written quote based on the actual soil result.

Geography & Site Conditions in Fulton, NY (Oswego County)

Fulton straddles the Oswego River in central Oswego County, on terraces stepped down from the surrounding lake plain. Upland soils across the commercial corridors are predominantly Colonie loamy sand and Elnora loamy fine sand, rapid-draining, non-cohesive, and characteristic of the Glacial Lake Iroquois bed, while the river terraces themselves carry Palmyra gravelly loam and Howard gravelly loam. Lower-lying parcels along the river edge run into Lamson very fine sandy loam and occasional muck.

The Oswego River controls base-level hydrology, and the city's historic dams and canal infrastructure still shape grading and permitting on riverside parcels. Commercial excavation in Fulton commonly involves trench-wall stability issues in the dry non-cohesive sand uplands, shallow groundwater and dewatering on the lower river terraces, and stormwater design that ties into both the Oswego River and Lake Ontario watersheds. Bedrock is generally deep through the city, though shallow shale and limestone can appear on the outer west-side ridges. Projects adjacent to the canal prism fall under NYS Canal Corp permitting. Frost depth in the sandy uplands pushes utility burial on most commercial work.
