Rehoboth’s approved wastewater projects include a pump station, a force main and an ocean outfall.

Status: On May 25, 2017, Delaware Department of Natural Resources and Environmental Control (DNREC) Secretary Shawn M. Garvin approved and signed the Secretary’s Order for the Rehoboth Beach ocean outfall which includes all required DNREC permits to move forward with construction. The U.S. Army Corps of Engineers will be issuing a permit along with a Sediment and Stormwater Permit from the Sussex Conservation District, and DelDOT permits for work on state road right-of-ways.

The approved pipeline alignment begins at the existing Rehoboth Beach Wastewater Treatment Plant, follows the Lewes and Rehoboth Canal north to Grove Park. The pipeline will then turn northeast to Henlopen Avenue and continue along Henlopen Avenue to the Deauville Beach parking area and terminate in the Atlantic Ocean, approximately 6,000 feet from the parking area. The 24-inch high-density polyethylene (HDPE) pipeline will be installed via horizontal direction drill approximately 3,000 feet and marine open-cut trench approximately 3,000 feet. Once the pipe is anchored in place with concrete collars, the open-cut trench will be backfilled. The terminus of the outfall pipe will consist of a 120 linear foot diffuser comprised of eight risers, 1.5 feet above the ocean floor, with four discharge ports per riser. The diffuser will be installed on pilings to ensure stability. 

The city is now advertising bid documents. Mobilization of equipment will begin in October 2017 with an anticipated construction completion in April 2018. Link to Secretary's order is below.
