The Greenest Residence in the Country

Seattle based RainBank Rainwater Systems is a proud participant in the construction of the greenest residence in the country.

Heron Hall, designed by Jason McLennan, included rainwater collection as its sole source of water for his residence.

RainBank Rainwater systems installed a 15,000 gallon Contain Water Tank, along with filtration and ultra violet disinfection for potable household use. Much of the vetting of materials were already part of RainBank’s design theory and were easily appointed for this project.

“Tracy and Jason F. McLennan discovered their front door in a corner at Earthwise Architectural Salvage in Seattle. Before serving as a department-store display, it was hand-carved in Afghanistan. “People were a little shorter then,” says Jason. “I’m 6-2. I had to build a pedestal for it.” Eventually, that pedestal will hold a quote: “All that can save us is a sustained awakening of the human heart.” (Steve Ringman/The Seattle Times)”

RainBank Rainwater Systems is pleased to be part of this worthy educational project.

Underground Containment at USC

In a move toward more sustainable practices, a new village on the campus of University of Southern California (USC) will host an underground rainwater collection and containment system.

According to an article in the Daily Trojan, “Water conservation at the new Village is an important lesson beyond the lecture hall,” said Vishnu Ratnam, an engineering graduate student. “It’s a good example to look at how you can put what you’ve learned to good use.”

The 15 acre property will have six underground wells and will be able to capture 200,000 gallons of water. The system will capture stormwater before it enters the Los Angeles River or the ocean, conserving water and promoting sustainability.

RainBank has designed and installed underground systems, which work particularly well in urban areas where space is at a premium. Click here to read more about a RainBank underground system.

400 Year Old Dependable Rainwater System Design

What do you do for domestic water supply on an island that has no rivers, lakes or a dependable water supply?

The inhabitants of Bermuda, a small island in the North Atlantic have been collecting rain water from their roofs for hundreds of years. The white stepped roofs, once made of limestone, are still being used today to collect rainfall to be stored for later use. The steps in the roofs, designed 400 years ago were meant to slow the flow of the water to be collected from gutters with the water being stored under the house.

Roofs like this one built in 1640 are the only dependable source of domestic supply for the island’s 60,000 inhabitants. Limestone roofs were heavy which in part was a good choice against high winds and the white limestone mortar had anti-bacterial qualities. This practice is now mandated in building regulations requiring 8 gallons of storage for every square foot of roof. To meet the demands of increased population growth and tourism, desalination is being introduced with six plants on the island producing 13,500 meters per day.

Necessity is the mother of invention. These early settlers, as well as today’s inhabitants,  are meeting their needs through conservation and cooperation.
