The beach replenishment is underway in Rehoboth Beach and Dewey Beach.

The pumping of sand started on Nov. 24 and will operate around the clock until completion on January 18, 2017.

The project will replenish sand, construct automotive and pedestrian dune crossings, install a sand fence, plant dune grass and install two storm water outfall extensions, the Rehoboth City Manager’s office reported.

During the past eight years, wave action has caused damage to the outfalls, and the city has been relying on temporary fixes.

The new outfalls will have a more robust design to withstand storm damage with steel pipe added for strength with an enhanced support structure around the pipe.

The project sponsor is the State of Delaware and the Department of Natural Resources and Environmental Control(DNREC).

TheU.S. Army Corps of Engineers is the design and construction agent and the contractor is Great Lakes Dredge & Dock Company.

The total costof theproject is $11.2 million. The corps will pay 65percent of that cost and DNREC will pay the remaining 35 percent. The city budgetedsufficient funds and will pay $946,500 for the outfall repairs.

The base contract called for 424,000 cubic yards of sand to be pumped. Additional optionsaccepted will increase this base amount to 653,000 cubic yards pumped with 384,000 for Rehoboth Beach and 269,000 for Dewey Beach.

For the two outfall extensions, the time slated forcompletion is June 15, 2017.

The Corps will use a new site located in theDelaware Seashore State Park where grain size of the sand matches the beaches of Rehoboth Beach and Dewey Beach.

Dredges extract the sand, and giant vacuums pull upsand and water. The intake travels through the grating that filters outdebris. The sand and water travel through an underwater pipelineto the beach.

The material gushes out the end of the pipeline into a “basket” that serves as a second filter to eliminate debris.

Any debris ishauled to the beach. Conventional earth-moving equipment then moves the sand
