SAN DIEGO -- A small group gathered on a recent afternoon outside a $1 million model home on Cloudbreak Lane here. The five-bedroom house offered a Mediterranean tile roof, teal-green shutters and arched entryway. Designer touches inside included a walk-in pantry, motion-sensing faucets and optional oversized wine cabinet.
But it was a plain, gray metal box on the side of the house that grabbed the most attention. Avery Kintner, a green building consultant, brought a group of students from University of California, San Diego, to see the box's secrets.
The 5-foot-wide container held pipes, filters, a tub and other mechanics. It's a system designed to help the future residents of this house survive the ongoing drought and any future ones.
