Landfill Cell Design and CQA

Mississippi County, Arkansas, owns and operates a 30-acre municipal solid waste disposal facility. FTN was contracted to design and perform construction quality assurance (CQA) services for the development of a new 4-acre disposal area. The design included the following:

  • A composite bottom liner system of two feet of compacted clay, a 60-mil HDPE geomembrane liner, a geocomposite drainage layer, and a protective cover layer;
  • A leachate collection, transmission, and storage system;
  • Stormwater control improvements including an expansion of an existing stormwater pond and stormwater drainage channels; and
  • General site improvements including new access roads and new survey control monuments.

FTN prepared construction plans, specifications, and bidding documents, and provided assistance to the county during the bidding and contracting phase of the project.
