Wagner House, Hawaii.  18 trussed HOGs store over 930 gallons of rainwater in a 2 foot wide trench 
936 gallons of rainwater stored for landscape irrigation.

Ed Wagner wanted to demonstrate that significant rainwater storage was possible in a "dead" space so he worked Rainwater HOG tanks like they have never been worked before.  8 HOGs trussed and joined using rigid 3" pipe and Ty Seals to make flexible, secure connections. A vortex filter plus the HOG 150 micron film ensures no debris enters the system, and water is pumped out for use around the garden.

Green Builders Depot in Hawaii supplied HOGs and advice.
