The Coastal Plain features flat terrain with naturally high water tables that create challenges for conventional septic systems. Many properties require advanced treatment systems, mound systems, or other alternatives designed to function where groundwater is close to the surface. Seasonal flooding and storm surge can also affect system performance in low-lying areas.
Dinwiddie County lies south of Petersburg with a mix of rural farmland and growing suburban development. Fort Barfoot (formerly Fort Pickett) military installation occupies a large portion of the county. As a Chesapeake Bay Preservation Act locality, mandatory pump-out every 5 years is required.
