Even the unchurched in Boulder, Colo., know that water is sacred.

Nestled between the high plains desert and the foothills of the Front Range, Boulder is known for its environmental awareness and outdoor sports. Joggers, bicyclists and in-line skaters in the city join hikers, rock-climbers, kayakers and skiers in the nearby mountains — all enjoying the 300 days of sunshine each year.

But lots of sunshine means little rain. Boulderites know all about water conservation and that summer lawn-watering restrictions are tied to winter snowfall. Water is scarce — and sacred.
