New Zealand's leading supplier of dairy effluent, leachate and water storage bladder tanks


The Flexi Tank is a self-supporting, safe, and enclosed bladder storage system capable of storing between 1,000 and 2 million litres of liquid. It can be quickly rolled out on a flat surface and connected to store water, dairy effluent, and leachates giving you economical, easy storage when you need it most!

Our happy customers use their Flexi Tanks all over New Zealand to provide essential storage for their projects, anything from horticultural water storage, dust suppression for earth works, or leachate storage on compost and waste dump sites. The Flexi Tank also works hard for dairy farmers, helping to keep the environment clean by storing dairy effluent to be re-used as valuable liquid fertiliser.
