Bay Park Conveyance Project
Summary
The Bay Park Conveyance Project, a partnership between the New York State Department of Environmental Conservation and the Nassau County Department of Public Works, will improve water quality and spur ecological recovery in Long Island’s Western Bays.
The project includes engineering design services for 3.6 miles (5.8 km) of force main microtunnel and 7.2 miles (11.6 km) of force main effluent conveyance pipe rehabilitation via sliplining. This will enable Nassau County to convey up to 75 million gallons per day (284 million L/day) of treated effluent from the South Shore Water Reclamation Facility to the Cedar Creek Water Pollution Control Plant, to be discharged via an existing ocean outfall.

Scope of Work
Delve Underground is the lead designer for the Western Bays Constructors JV design-build team and is responsible for trenchless and geotechnical engineering designs, as well as leading the large, multidisciplinary design team for the entire project. This includes subsurface structures including deep shaft support of excavation for microtunneling and sliplining, wet well and pump station foundations, and structural design for the new pump station.
Challenges & Innovations
The Bay Park Conveyance Project is the largest trenchless and first of its kind design-build contract to be awarded in New York State and in the East Coast.
