The tanks are manufactured under license to Containment Solutions Inc, formerly Owens Corning Tanks, who have manufactured in excess of 250,000 tanks in the United States, dating back to 1964.

The tank technology is licensed worldwide, with manufacturers in over ten countries. Tanks are used for safe containment of wastewater, petroleum products, potable water and industrial chemicals where longevity and the prevention of ground contamination are paramount.

Above ground storage tanks and bolted panel tanks are also manufactured for wastewater storage where burial is not suitable.

Multiple tank configurations are also used to reduce cleaning requirements in small pump station overflows through serial high/low connection of several tanks.

Fibreglass manholes and sumps are factory made in all fibreglass construction ready to be placed directly into the ground. The units are factory assembled, with inlets and outlets where possible. All factory joints are totally leak proof. Groundwater infiltration is not possible.
