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.
Mathews County is a small peninsula locality nearly surrounded by Chesapeake Bay waters with no incorporated towns. Extremely high water tables and extensive tidal wetlands make onsite wastewater management challenging. As a Chesapeake Bay Preservation Act locality, mandatory pump-out every 5 years is required.
