In 2013 the Municipality of Anchorage Solid Waste Services (SWS) decided to combine the next two planned landfill Municipal Solid Waste (MSW) cells 11 and 12 into a combined cell 11/12. They also wanted to expand their construction and demolition debris (CDD) capacity by adding a new CDD cell, Cell 8B, and improve the leachate management facilities to eliminate difficult to maintain piping and valves. As part of a multidisciplinary project team, BHC was responsible for the design of the lining and leachate collection systems, as well as improvements to the leachate pretreatment facilities.
