Construction of Perimeter Floodwall, Stormwater Pumping Stations and Stormwater Collection System

Location: NEWARK, NJ


Railroad Construction Company, Inc. along with Joint Venture Partner, Posillico Inc. (Railroad / Posillico JV, LLC), have been busy completing new construction and implementing upgrades to an existing plant in Newark, NJ, all designed to improve flood mitigation.

Work is concentrated on three main segments:

  1. Perimeter Floodwall
  2. 3 Stormwater Pumping Stations
  3. Upgraded Stormwater Collection System

The new perimeter floodwall will wrap around the east and west sides of the facility to protect it from flooding – totaling 2 miles in length. The reinforced concrete footing and stemwall is a pile supported structure using both vertical and battered (angled) piles with drilled caissons and concreted filled pipe piles.

The 3 new stormwater pumping stations that are being constructed will help protect the nearby area by pumping away large volumes of water, helping to prevent flooding. Each facility will include wet wells, pumping equipment for stormwater and dewatering and an electrical control room.

The existing on-site stormwater collection system will be upgraded to an increased capacity by installing larger pile supported drainage piping and structures, and a new larger lift station.
