Across the globe, clean
water resources are shrinking as the world's population expands. Communities
must find new ways to conserve water. In Songdo,
South Korea, a new city built from
scratch, developers have come up with innovative solutions. Peter Lee,
Sustainable Design Specialist, Cosentini Korea: We didn't just look 10 years
ahead; we looked at 50 years, a hundred years from now. And saving water is one of the key elements
that we tried to pursue, in terms of sustainability. Stan Gale, Chairman, Gale
International:We trap the rainfall that comes into Songdo. We store it in
containers, and then we use that gray water for all of the irrigation. Scott
Summers, Vice President, Gale International:That gray water is used back into
the city for commercial buildings, to flush our toilets, and it's used for
washing down the streets. Peter Lee:
Each site has a district gray water storage tank, so it can actually
reduce your water and sewage costs. Lee Jong-Cheol, Commissioner, Incheon Free
Economic Zone: Wastewater is also
processedand re-used inparksand industrial facilities. Stan Gale: Another area
for water conservation is we have a mile and three quarters long canal. It has
millions and millions of gallons of water in it, but the seawater is plentiful.
We take the mud and sand out of the ocean water and the canal is recirculated
with clean ocean water. Lee Jong-Cheol:
We're building an environmentally friendly system that is unique to any
other in the world. Songdo's innovations will help the city reach its goal of
using at least 30 percent less water in its commercial buildings. As growing
demand strains the world's natural resources, Songdo serves as a model for
water conservation everywhere.
