If you are one of those people who collects rainwater to save on utility output, you know that the barrels typically used are large and unsightly. This Eco-Sac, or as we have come to call it, Eco-Bladder, is a flexible eco-friendly rainwater storage unit.
The Eco-Sac can fit nice and snug under a patio, deck, or floor and are made with a PVC material bonded by high frequency welding, which means this bladder won’t leak like your grandparent’s bladder does. The PVC material is also algae resistant. — Andrew Dobrow
