H & L Contracting details emergency repairs to underwater diffusers at the Cedar Creek Wastewater Treatment Plant’s ocean outfall in Wantagh, New York, located in the Atlantic Ocean. The project, led by Jeffery Hawkins, will run from July 16 to October 31, 2026, operating Monday through Friday from 6:00 AM to 5:00 PM. Work will be conducted from a dive vessel, tug Manhasset Bay, and marker buoys, with vessel communications managed via VHF channels 16 and 65. The operation involves installing location buoys along the 84-inch outfall pipeline, which extends approximately two miles offshore and branches into an east-west diffuser field, each leg measuring about 1,225 feet. Commercial divers will mark the pipeline alignment to facilitate inspection and construction. The four key coordinates of the diffuser field are: 40-34.08N 073-27.28W; 40-33.78N 073-27.15W; 40-33.97N 073-26.34W; and 40-34.27N 073-26.47W. Vessels can be moved with 15 minutes’ notice to avoid impeding navigation.
Valid 2026-09-21 to 2026-10-31.
