Nundah State School II Brisbane, Queensland II Australia
104 HOGs in the school colors hold 5,700 gallons for irrigation, toilet flush…and teach students about gravity and water pressure!
Year of Install: 2007
Installation Stats: 114 HOGS are grouped around the library building to capture water from each downspout. Made to order in the school colors of yellow and black, the tanks are installed at different elevations on different sides of the building.
Annual Water Capture: 5,700 gallons
HOG Skills: The different elevations demonstrate how a gravity feed system affects water pressure (higher elevation + full tank = maximum pressure). The Nundah library uses ultra-low-flush Caroma toilets and flushing these with HOGS saves the school more than 28,000 gallons of water per year.
Where is it Now? Six years later, our modular rainwater catchment system continues to capture rainwater, flush toilets, and teach the next wave of students.
