The Whole HOG: Aug/Sept 2013

Water-centric Green Design News

We’re hitting the books this September with a filled-to-the-brim back to school edition of The Whole HOG. Three stand-out school installations, from Nundah State School, the Dalton School, and Omaha North High School, demonstrate how valuable HOG tanks can be in the classroom – indoors or outdoors.

We’re catching up with Team ASUNM as they prepare their SHADE home to compete in the Solar Decathlon 2013. They’re bringing six HOG tanks with them. And in our B.U.G. Design section, we take a closer look at the winning Illawarra Flame House (from an Australian team) in the China 2013 Solar Decathlon. Fellow Aussies and HOG founders, Sally and Simon Dominguez, say “Good on you, mates!”

Speaking of green student design competitions, registration for the 2013 Campus Rainworks Challenge has begun! Check out our HOG giveaway for competing student teams.

Aug/Sept 2013: Nundah State School

 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!

Yellow and black HOGs mounted on the library peek out from behind the foliage at Nundah State School.

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.
