Collapsible Water Storage Tanks solve an Emergency Situation

Flexi Tanks NZ were thrilled to be able to help a major swimming pool complex avert an emergency situation recently.

The pool is currently undergoing an upgrade to enable it to be classed as an Olympic sized pool and has been empty for a while during the upgrade. The pressure from a rising water table under the pool was putting pressure on the pool bottom.
Weight was needed in the empty pool to equalise this pressure, but work also needed to continue in the pool.
Solution?? Flexi Tanks NZ to the rescue!
Within 24 hours we had organised, delivered and installed 3 Flexi Bladders on the pool bottom to create 450 tonne of opposing pressure with water in the 3 tanks. Crisis averted and all contractors happy!
