This 30-acre landfill expansion consisted of a 27-acre double composite liner system and a 3- acre singled-lined vertical expansion over portions of the existing on-site Class III landfill. The design included a number of innovative elements to increase current and future capacity. This design also helped reduce the construction and operational costs of the facility.
We constructed portions of the Phase V bottom liner below the seasonal high water level, resulting in a significant reduction in backfill material requirements and the generation of more than 200,000 cubic yards of soil for landfill operations. The design also included a unique leachate collection system liner flap and pump stations ready for future expansion to the east of the Phase V facility.
