The Aquascape 2,500 Gallon Water Storage Kit is the easiest way to create a sub-surface water storage reservoir for use in rainwater harvesting systems. The completed underground reservoir can be used to store up to 2,500 gallons of collected rainwater. The pre-packaged kit comes complete with 80 AquaBlox® Large Water Storage Modules, a 25' x 30' 45 mil EPDM liner, two 750 sq. ft. panels of non-woven geotextile underlayment, and four Pondless® Waterfall Vault Extensions. When constructed, the components will create a basin that measures 11' x 12' x 5' deep. A variety of other available water storage kit sizes allows you the flexibility to choose the reservoir size that best suits your application.
