Made of two layers of 4-mil food-safe plastic with durable heat-welded seams, the bladder holds up to 95 U.S. gallons and serves as a watertight liner for a walled structure that you build. The plans show how to make a 36" x 28" x 21" container (holds up to 65 U.S. gallons), which can be painted or stained to match decks and fencing. Also included are all the exterior-grade screws you need, plus a selection of UV-resistant PVC hose fittings for connection to a header hose and diverter that you supply. The completed rainwater reservoir can be placed 70' or more from a downspout (depending on elevation).
A simple, practical garden project within the skills of most. Lumber not included.
