The Gloucester County Improvement Authority (GCIA), along with the Borough of Woolwich and the Borough of Swedesboro in a joint venture, will be constructing two force mains within the following municipalities: South Harrison, Swedesboro, Woolwich and East Greenwich. RVE provided engineering and permitting services for the construction of a new force main from the County landfill located in South Harrison Township to the Gloucester County Utilities Authority (GCUA) sanitary sewer interceptor (Mantua Main) located in East Greenwich Township. The new force main construction will total approximately 10 miles of piping and include two pump stations. The first pump station is proposed at the landfill. This pump station will pump leachate from the landfill to a second pump station proposed at the Swedesboro Wastewater Treatment Plant. The Swedesboro Pump Station will pump the effluent to the GCUA Mantua Main in East Greenwich. Once the force main and pump stations are operational, the Swedesboro Wastewater Treatment Plant will be decommissioned. Both pump stations are being designed by others but have been included within the permitting scope of RVE’s project.
The purpose of this joint venture between the three governmental agencies is to reduce their overall annual budget in sewerage fees and to expand the GCUA sewer service area.
Construction of the force main will eliminate the necessity of hauling the leachate on local roadways through multiple municipalities to the treatment plant.
There are four stream crossings associated with the project. At these crossings, the force main will be either directional drilled under the waterbody or attached to an existing bridge. The project also includes crossing three high pressure natural gas transition mains.
