THIS is a fascinating concept... rainwater collection in a "tank" that's actually a collection of boxes in an EPDM rubber liner membrane below ground - under your patio or decorative gardens or even driveway (it's designed to take car loads up to 38psi). A large scale storage unit that's compact to ship, easy as a backyard pond to assemble, and takes up no excess room in your property. What could be more perfect in the tiny lots we've got here in the urban environment?! They're even made of recycled materials. The decorative water elements they package the systems with are designed to aid in filtration and oxygenation of the water, helping prevent sepsis. Really curious about how installs turn out, and what the long term results are like...
Now if only it could operate without the electricity usage.
