Sussex County Wastewater Master Plan. Sussex County, Delaware.

Since 1995, WRA has provided Sussex County with Wastewater Planning Services, including master plans for their two largest planning areas, the North Coastal and South Coastal Planning Areas.

The comprehensive regional planning studies focused on the Inland Bays and South Coastal Regional Wastewater Facility Planning Areas. These areas are projected to serve 126,000 and 90,000 equivalent dwelling units (EDUs) respectively at build-out. The projects required performing a land use and zoning analysis to estimate buildout EDUs and wastewater flow projections, the development of regional collection, conveyance and treatment alternatives, and the evaluation of existing infrastructure including gravity sewers, force mains and pump stations. Additional tasks included hydrogeological studies, exploration of wastewater disposal technologies, preparation of environmental assessments and detailed cost estimating, mapping and hydraulic modeling of existing sewer districts, and a review of an ocean outfall alternative for each planning area.
