Geocomposite Alternative to Granular Groundwater Drainage Layer in Dubuque Landfill Cell 9 Expansion

Background

The Dubuque Landfill Cell 9, Phase II is located in Dubuque, Iowa. The original liner system (from bottom up) consists of 1 ft (30 cm) groundwater collection layer, 8 oz/sy (270 g/m2) separation geotextile, 1ft (30 cm) earth barrier layer, 2 ft (60 cm) compacted clay layer, 60 mil (1.5 mm) HDPE liner, 8 oz/sy (270 g/m2) protection geotextile, and then 1ft (30 cm) leachate collection drainage layer.

GSE provided an alternative drainage layer to replace 12 inches of the granular groundwater control layer and 6 inches of the earthen barrier layer. This produced a revenue gain of over $650,000 from the air space savings.
