Client Name: NERC Middlesex Gas Company, Trumball, Connecticut

The Middlesex County Utilities Authority (MCUA) ap­proved a plan for a state-of-the-art system that will uti­lize the methane gas produced from decomposing solid waste in the Middlesex County Landfill, to generate both electrical power and significant cost savings for the MCUA. The project includes the construction of a com­prehensive network of pipelines, through which the methane gas will be collected from three area landfills, and transported to an electrical power generator at the MCUA’s Sayreville headquarters.

Edgeboro International Inc. (EII) has operated the landfill gas collection and control systems of the following landfills: Edgeboro Landfill, Middlesex Landfill, Edison Landfill and ILR Landfill from 1947 to 2005.

EII was retained to install six miles of pipeline through various elements, including solid waste, soil, hazardous waste sites, wetlands, tidal areas, and two river crossings. A 16-inch methane gas main was installed by Edgeboro International to interconnect NERC’s three landfills to supply fuel to a newly con­structed 18-megawatt power plant. Construction involved trenching through the above elements at depths of 5-10 feet in which SDR 32.5 16- inch pipe was laid within the specifications and requirements of the owner.
