The Bay Park Conveyance Project in New York state, which’s intention is to decrease nitrogen pollution in Long Island’s Western Bays by redirecting treated water through a pollution control plant to an Atlantic Ocean outfall has acieved to the tunneling completion. Almost 18km of tunneling and around 11.5km of sliplining of an abandoned 100-year-old aqueduct pipe are the contents of this project.
The date of commencing work on a design-build contract by Western Bays Constructors, that is a joint venture of John P Picone and Northeast Remsco Construction, was 2021. While bulding of fourteen shafts were completed by two micro TBMs which were launched in 2022, twelve tunneling drives were completed to lay the 1.8m diameter pipe at depths of 6-18m.
Also in order to minimising disturbance to surrounding communities, reducing cost and accelerating construction, Micro tunneling was chosen for the project.
New York governor Kathy Hochul said:.”The Bay Park Conveyance Project is one of the most innovative infrastructure projects in the nation and an example of our State’s commitment to securing a healthier and more sustainable future for New Yorkers. With the conclusion of this phase of work, we are making important progress to ensure Long Island has access to clean water and create healthy and resilient ecosystems.”
