The Tri-City Regional Landfill is located in Petersburg, Virginia along the Appomattox River. Container First Services (CFS) purchased the landfill from the City of Petersburg with the goal of rehabilitating the landfill and expanding it to generate additional revenue for the owners and the City. CFS teamed with Advanced Wall Technologies, LLC (AWT) to expand the landfill using AWT’s patent-pending expansion technology. The patent-pending technology includes the use of encapsulated waste products in the construction of berms, including mechanically stabilized earth (MSE) berms, for vertical and/or lateral expansion of landfills. This project is the first MSE berm to be permitted and constructed in Virginia, and is the first use of the patent-pending technology. CFS retained AWT and Geosyntec for our expertise in the design and construction of MSE berms to add credibility to the design and permitting process.
AWT & Geosyntec Scope of Services
Geosyntec designed a maximum 50-foot tall and 2,500-foot long MSE berm consisting of a typical reinforced earth zone and an encapsulated fossil fuel combustion product (FFCP) retained zone. The encapsulation includes a flexible membrane liner and geosynthetic clay liner that encapsulates the FFCPs and directs leachate to a toe drain that discharges into the existing leachate collection system. The MSE berm design is the first of its kind in which encapsulated waste product is used to offset the costs of using traditional structural fill.
The permitting and construction of the MSE berm at the Tri-City Regional Landfill is a project of firsts. The berm is the first to be permitted and constructed in the state, and is the first of its kind to use encapsulated waste products to offset the use of structural fill. As part of the permit process, AWT & Geosyntec educated the Virginia Department of Environmental Quality in the proper design, maintenance, closure and post-closure care of MSE berms, and our reputation and expertise led to the successful permitting of the project within an accelerated permitting schedule. The corresponding landfill expansion will provide 3 years of additional disposal life for our client.
Construction of the first phase of the MSE berm is complete. Additionally, AWT will work on the team designing and permitting a MSE berm around an unlined landfill cell adjacent to the first expansion cell.
