Project Scope:

Supply  and installation of geomembrane liner, cuspated 3m drains, biaxial 1m drains, fabricate and place ballast bags, and drainage sumps.

The Golders design incorporated a drainage system with five cuspated drain arterial channels wrapped in filter fabric with a herringbone system of feed channels of filter fabric wrapped bi-axial drain.
