Bladder Water Storage Tank

Flexible Water Tank for Rainwater Storage

rainwater bladder tankRain Water Bladder Water Storage Tanks are one of the most cost effective options for rainwater collection, storage and reuse. Low profile enough to store under decks, homes, patios or in basements, these tanks are an excellent water storage solution for areas with unused or limited storage space.

Rainwater Bladder Tanks are constructed from a flexible material that rises as the tank is filled with liquid. This design makes the tank easy to ship and small enough to fit through doorways or in tight storage spaces. Depending on your rainwater collection requirements, tanks may be built from either a standard non-potable water fabric or a potable drinking water storage material.
