Stormwater Harvest Tanks

The Cantex Storm water Infiltration tanks are one of the most preferred methods of stormwater management, when downstream discharge facilities are not present, or post development runoff volume is limited. The Cantex Infiltration Tank Modules are wrapped in needle punched non-woven geotextile and buried in porous permeable soil base. The Infiltration systems help to recharge groundwater aquifers and provide moisture for the surrounding vegetation. The Cantex Infiltration systems are recognized by the international stormwater best management practice.

The Cantex Tank Module system is far more efficient and durable than any traditional gravel and pipe-based systems. The system provides a void space ratio of over 95% compared to 30% in typical gravel and pipe-based systems. Consequently, the Cantex system offers a smaller footprint for the same storage volume, significantly saving the amount of excavation, soil transport, importing clean aggregate and thus reducing earthworks related installation costs, and causes minimum site disruption.
