Soil & Terrain Characteristics

Allegheny County sits at the confluence of the Allegheny, Monongahela, and Ohio Rivers on the Pittsburgh Plateau. Soils are derived from Pennsylvanian-age sandstone, shale, and coal measures. The hilly terrain creates variable conditions with well-drained upland soils and poorly drained valley and hillside soils. Many areas have been disturbed by coal mining, steel production, and urban development.

County-Specific Considerations

Allegheny County includes Pittsburgh and its suburbs, where most properties connect to public sewer through ALCOSAN. However, rural areas in the northern and southern periphery still rely on on-lot systems. The county's industrial legacy includes brownfield sites where soil contamination can affect system design. Landslide-prone hillsides in clay soils create additional challenges for system placement. The Allegheny County Health Department is active in sewage management oversight.
