Wilmington Landfill Vertical Expansion
Wilmington, Ohio

Wilmington Landfill, Wilmington, Ohio Client: City of Wilmington, Ohio

Hull teamed with the City of Wilmington to design a vertical expansion over the existing waste area to extend the life of Wilmington Landfill, which was scheduled to be closed in first quarter of 2009.  Hull’s activities included:

• An expansion design consisting of placing a separatory liner system and developing disposal areas for future operation;
• Designing a leachate collection system of the expansion area to use gravity to convey the leachate to the existing sump; and
• Designing the soil liner portion of the cap to serve as the soil liner of the expansion area, since the majority of the site has an existing single composite soil liner system.

This design extended the life of the landfill by about 14 years and enables the City to continue utilizing the same facility for solid waste disposal.  The expansion permit was reviewed and approved by the Ohio Environmental Protection Agency (EPA) in less than 12 months after the submittal.
