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: Omaha North High School

The high school students at Omaha North installed their HOGs themselves, learning the practicalities of rainwater catchment and reuse, and irrigating their school garden.

“The Rainwater HOGs fit perfectly,” said Lee Kallstrom, Engineering Technologies Department at the time of the installation. Two years later he reports, “I’m still extremely happy with your product.”

Year of Install: 2011

Installation Stats Omaha North magnet high school built a LEED silver four-story addition and a two-story greenhouse. Two HOG tanks are in the wedge between the new and old building collecting rainwater for landscape irrigation, and one waters plants in the greenhouse. “I can water the entire place in 5 minutes when I turn the HOG on,” says Lee Kallstrom from the Engineering Technologies department.

Science, engineering and technology are the focus at Omaha North magnet high school in suburban Omaha, Nebraska. With students doing the hands-on installation themselves, they learn practical construction techniques alongside the sustainability principles taught in the technical curriculum and illustrated by the building and greenhouse.

Where is it now? The school, which earned a silver certification for its sustainable addition, is the first in Nebraska to be certified under the LEED for Schools system rating.

By building green, Omaha North H.S. reduced its energy use by 20% and its potable water consumption (with low-flow sinks, dual-flush toilets, and rainwater tanks) by 43%.

In the winter of 2012, “the wedge” platform gave way in -20ºF temperatures. Students rebuilt in the spring (at a height of 24 inches to allow the water to drain completely from the tanks) and took the extra security measure of strapping the two HOG tanks to the building.
