How Do Bolted Rainwater Collection Tanks Hold Water?

Want to know how we hold water in rainwater harvesting tanks that are bolted together?

RainBank employees hang a 25 mil. PVC liner for an 18,000 gallon tank.

In order to hold water in rainwater collection tanks that are bolted together, first a heavy geo-textile pre-liner is hung against the steel wall panels to eliminate abrasions from the steel.

Then the liner is hung from the upper row of horizontal bolts.

Plumbing penetrations are made through the cement floor or through the steel walls with flanges.
