Damage-Resistant Practices for Designing Septic Systems in Coastal High Hazard Areas

Septic systems along sections of the Delaware shoreline can leach wastewater into coastal waters if they’re not properly located, constructed, and maintained.

Failed septic systems can lead to pollution and public health concerns through the release of untreated waste into adjacent coastal and marine environments, resulting in contaminated bay water, bottom sediments, shellfish beds, and beaches.

Special design criteria must be used to protect septic systems in areas vulnerable to high-velocity flooding, wave action, erosion, and storm damage.
