Project Overview

This project took our crews to the Old Dominion landfill, where we constructed a 12-acre geosynthetic lined MSW landfill cell. We also installed an HDPE leachate force main system around the perimeter of the site, along with four pump stations, two valve vaults, and seven force main vaults. Additionally, we constructed perimeter access roads and a wick drain system.

The initial excavation consisted of hydraulic fill from past quarry operations. The excavation depth reached 80 feet below the existing grade, into a wet Miocene clay layer formed when Richmond was under the ocean 10-15 million years ago. Due to the large volume and saturation of the material, we had to manage numerous stockpile areas in order to meet an aggressive project schedule.
