Why Flexi Tanks for Industrial Liquids
Industrial sites and landfills often need reliable storage for wastewater and leachate without the cost or delays of permanent tanks or ponds.
Flexi Tanks provide a fully enclosed, self-supporting solution that can be installed quickly and connected to existing collection systems. They are used across New Zealand for both temporary and long-term storage of industrial liquids.
Common uses include:
Wastewater storage — ideal for industrial processes, construction projects, and temporary treatment facilities where large volumes need to be contained safely.
Leachate storage — a secure option for landfill leachate. Tanks can be rapidly installed during weather events and connected to existing leachate systems. Chemical-resistant options are available depending on your requirements.
Because they are fully enclosed, Flexi Tanks help reduce the risk of environmental contamination. Tanks under 500 m³ can also be relocated if site needs change, giving you greater flexibility than fixed storage solutions.

Emergency Situation Solved
During the upgrade of a pool to meet Olympic standards, the empty pool faced pressure from a rising water table.
To equalize this pressure while allowing work to continue, Flexi Tanks NZ provided a solution. Within 24 hours, three Flexi Tank bladders were organized, delivered, and installed on the pool bottom, creating 450 tonnes of opposing pressure with water in the tanks.
This averted the crisis and satisfied all contractors involved!
