Project Description

Project Overview

D&B performed design and CM work for various pumping station projects where sewage flow bypassing, scheduling, construction sequencing, community relations, traffic maintenance, removal and replacement of sluice gates and other mechanical equipment, soil excavation and disposal and cleaning and removal of debris were involved.

Rehabilitation of the Lawrence & Peck Pumping Station

This work rehabilitated and upgraded the pumping station which served among other areas, the 1965 Worlds Fair to a firm capacity of 14,000 gpm (10 mgd)utilizing submersible pumps in the dry pit mode. Also included was the rehabilitation or replacement of structural, architectural, mechanical, electrical, plumbing, heating and ventilation equipment and the construction of an above grade superstructure to house the new electrical controls. The construction included a successful presentation before the NYC Art Commission and a sequential replacement of all major structural supports in the wet well area while maintaining the structural integrity of the station.

Rehabilitation of the Little Neck Pumping Station

This work rehabilitated and upgraded the pumping station to a firm capacity of 2,000 gpm utilizing submersible pumps in the dry pit mode. Also included was the rehabilitation or replacement of all structural, architectural, mechanical, electrical, plumbing, heating and ventilation equipment and the construction of a watertight below grade electric room.

Expansion and Rehabilitation of Conner Street Pumping Station

1975 expansion of the existing 3.5 mgd pumping station to a firm capacity of 11.5 mgd. It included the addition of a new electrical substation, flow metering facilities, multiplex telemetry system, replacement of virtually all the mechanical, electrical and ventilating equipment, as well as structural and architectural repairs. In 1985, our firm was awarded the second rehabilitation of this station. During this design submersible dry pit pumps were installed, the superstructure modified and complete structural and mechanical upgrading occurred. The 5,000 LF 24” dia. force main was also replaced. Construction involved rock excavation, piles and maintaining traffic around Co-op City.

Rehabilitation of Ely Avenue Pumping Station

This work rehabilitated and upgraded the pumping station to a firm capacity of 1,100 gpm utilizing submersible pumps in the dry pit mode. Also included was the rehabilitation or replacement of all structural, architectural, mechanical, electrical, plumbing, heating and ventilation equipment and controls.
