Santos - Leewood Waste Water Treatment Ponds

Projects ~ Liners

Principal: Santos
Head Contractor: Daracon Group
Location: Narrabri, NSW

Project Scope:

Fabtech was engaged by Daracon to undertake the supply and installation of geomembrane lining systems to four of Santos’ waste water treatment ponds.

Additional Information:

The complex multi-layer design was specified for four ponds, including two brine ponds, and required 720,000m2 of material. Also included in the design was a leak detection system and depressurisation drainage system. The layering included GCL, secondary HDPE, geocomposite drainage net, primary HDPE and a permanent ballast system. Fabtech’s lining system was recognised by Santos, Golder Associates and Daracon for the quality of the system and the leakage rates, which exceeded the industry standards.
