Article: Reconstructing and Relining Nottingham Lake in the Rockies

FGI Member, Simbeck & Associates, worked with Ewing Trucking & Construction, to install a new pond liner to Nottingham Lake, which is nestled high in the Rocky Mountains in Avon, Colorado.,  This man-made lake was built more than 32 years ago. It was originally PVC-lined with an expected 20-year life span. The geomembrane liner worked longer than expected; however, by 2012 the city’s engineering department was struggling to keep the leaking lake full.

The liner had been repaired twice and in the course of those repairs, it was discovered that the liner had significantly deteriorated. Other changes made to the lake during its 32-year history further degraded the geomembrane liner, including installation of irrigation piping and construction work for the pumphouse dock and fishing pier. During special events, buoys were placed in the lake. Sediment removal, soil erosion, and exposure to sunlight also contributed to the liner’s deterioration.

Installing a new pond liner would not normally pose a challenge for experienced geomembrane contractors. On this project, however, the contractors were not allowed to use any park area surrounding the lake to stage equipment and materials.

Secondary Containment System with EVOH For Auto Recycling Site

Recently, operators of a new auto shredder operation facility in Indiana installed a secondary geomembrane barrier with an internal EVOH (ethylene vinyl alcohol) layer beneath a hardscape pad in order to prevent metal, fuel and fluids contamination of soils and groundwater. According to the American Society of Civil Engineers’ Report on American Infrastructure, geomembranes used in waste management have become the most advanced sector of engineering in the United States. However, not all geomembranes are created equally. For instance, 60-mil high density polyethylene (HDPE) geomembranes are not entirely effective at preventing gas migration of volatile organic compounds (VOCs). In order to achieve gas impermeability, an additional gas-barrier layer must be used in a lining system or a geomembrane enhanced with an internal gas layer, such as EVOH, must be utilized.
