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.
