  • (soft music)

  • - Here on the snowy slopes of Mt. Hood, Oregon,

  • it seems impossible

  • that the U.S. could ever run low on water.

  • But government-backed research says it could,

  • in little more than 50 years.

  • (gurgling water)

  • Oregon relies heavily on snow melt for its fresh water.

  • But when the winter snows fail,

  • it can cause severe water shortages in the summer.

  • And those snows are failing more.

  • (gentle music)

  • Today I've come to the City of Portland

  • to meet Kyle Anderson, lead architect

  • of Hassalo on Eighth, an innovative housing development

  • where technology is helping to significantly

  • reduce residents' water footprint.

  • - The one thing about this project,

  • what makes it real unique,

  • is that we had the opportunity to have critical mass.

  • You know, to take three acres of asphalt

  • and bring on a million square feet

  • of 657 apartments, all of a sudden the demand

  • for the resources becomes much higher.

  • So, the savings become that much higher as well.

  • - And so talk to me about the red tanks.

  • This is the NORM system.

  • - So, NORM is an acronym for

  • Natural Organic Recycling Machine.

  • This development treats all black and gray water

  • on site for the residents.

  • We basically are harvesting water.

  • All of the apartments for flushing toilets,

  • for watering gardens, we're treating 45,000 gallons

  • of black and gray water daily.

  • And then we just celebrate it.

  • It becomes part of the vernacular of the architecture.

  • We call it science on display.

  • Actually drove people to this development.

  • As we build more and more

  • and we get denser and denser

  • this is going to become more and more important.

  • Maybe we should be approaching infrastructure

  • in a different way.

  • - There are a lot of simple and accessible technologies

  • that have been put into this building

  • that we can use in all our homes.

  • - Hi, good to see you. - Hi, how are you?

  • - Talk to me a little bit about the water saving

  • features in the building.

  • - We have compact four gallon dish washing system,

  • the low-flow shower, and the front loading washers

  • and dryers.

  • - You didn't think about all these sustainable things

  • but they're already just built in for you.

  • - Sustainability by design, right?

  • And it's becoming like the new norm.

  • - But many homes in the U.S. still use

  • standard top-loading washing machines

  • that can use around 45 gallons of water per load.

  • But front-loaders use as little as 13.

  • - And many of us still rinse our dirty dishes

  • under a running faucet before loading them

  • into the dishwasher.

  • This is a huge waste of water

  • because you actually need the dishes to be dirty

  • as the enzymes in the detergent latch onto food particles

  • to work effectively.

  • It's these small actions done by housebuilders

  • and homeowners across America that can

  • add up to big water savings.

  • And that can make a huge difference

  • to our nation's water security.

  • (upbeat music)
