Bay Park Conveyance Project:
SOE for 14 Shafts on a Microtunnel Alignment
In February 2021, Western Bays
Several projects are underway in
Nassau County, New York, to improve
water quality in the Western Bays of
Long Island. A major piece in accomplishing
this is the Bay Park Conveyance
Project. When completed, it will divert
most of the treated effluent away from
the Western Bays to an existing ocean
outfall at the Cedar Creek Water Pollution
Control Plant. The ongoing works
include 3.6 mi (5.8 km) of microtunneling,
7 mi (11.3 km) of sliplining,
14 shafts and a 75 million gal (284 million
L) per day pump station.
Constructors (WBC) - a joint venture of
John P. Picone and Northeast Remsco
Construction - was awarded the
design-build contract. For final design,
WBC retained Delve Underground to
lead the design team for the project.
Delve Underground worked in concert
with WBC and its subcontractor, Keller,
to determine optimal shaft construction
methodologies, and during tender,
evaluated options that would limit
groundwater inflows to the allowable
limits. This article focuses on how

support of excavation (SOE) was
selected for the 14 primary shafts for
the microtunneling efforts as well as
key design components to address shaft
performance needs.
Surface and Subsurface
Conditions
Most of Long Island's south shore is
densely developed with primarily lowrise
residential and commercial
structures. There is minimal topographical
variation in elevation.
