Wastewater Treatment Plant Improvements

The City of Rehoboth Beach is undertaking an approximately 10-year, $70 million project to make critical improvements at its wastewater treatment plant. The city currently is in the midst of Phase 3 of the four-phase project. Associated completed projects include construction of the ocean outfall, installation of an ocean outfall force main, and replacement of the effluent pump station.

Phase 3 includes mixer replacement (which has been completed) as well as construction of a new dewatering facility and conversion of existing aerobic digesters to waste sludge holding tanks, which is underway. Phase 3 work is expected to be completed by the end of 2024.

Phase 4 work, expected to get underway in early 2025, will include installation of new plant controls; replacement of chemical feed systems, all sludge and scum pumps, HVAC equipment, flow control equipment, and water pumping systems; renovations to the dewatering building; and miscellaneous architectural repairs.
