Flowcrete's Flowcoat SKN was specified for use in the on-site wastewater treatment plant, which collects and treats effluent generated through precipitation entering the landfill as well as moisture secreted from decomposing waste material. The plant facilitates the discharge of treated water to a sanitary sewer or water body. 

Over recent years, on-site leachate treatment has become an increasingly popular alternative to the high costs and stringent criteria associated with hauling leachate to a third-party wastewater treatment plant. 

For the past 20 years the Cache Creek landfill site has been used as a large transfer station for Vancouver, however following the expiration of the previous operator’s contract was closed in December 2016. 

The plant is currently being used to treat groundwater effluent as part of the on-going post closure care and maintenance process. 

Daily operations at the plant can potentially expose the floor to spillage of concentrated leachate, sulphuric acid (98 percent), sodium hydroxide (50 percent) and biocides. 

Flowcoat SKN is a 100 percent solids epoxy Novolac coating system, ideal for harsh chemical and solvent resistant applications, best suited for use in secondary containment, solvent storage, pump pads, trenches and other high exposure areas. Flowcoat SKN offers a higher chemical resistance grade to standard epoxies and polyurethane coating systems. 

The material was installed by Flowcrete STAR approved applicator, Marvellous Ideas.

“Even just intermittent spillage of chemicals used could lead to severe corrosion of the surface over time," said Marvellous Ideas Owner Don Podolsky. 

Cache Creek is currently operating only for local residences, however, with the go-ahead for an extension to the site will re-open under a new operator in 2018.

The landfill extension will have the same capacity as the original Cache Creek Landfill, about 10,000,000 tons, and has a slightly larger footprint.
