Water is one natural resource that is abundant and inexpensive. Perhaps too cheap, according to Dave Carlson, Director of Project Engineering for Columbia University, who believes that we don’t value water enough. Nevertheless, most Columbia buildings have been converted to low-flow plumbing, and miles of leaky pipes underground have been replaced. Old hot water heaters have been changed to highly efficient systems and most of Columbia’s housing stock has been metered. Anomalies are investigated for any problems that exist with the underlying foundation.

Still, improvements can be made. Columbia has a chance to take the lead in water conservation because its representatives sit on the U.S. Building Council committee that sets water conservation standards for buildings across the country. In fact, the University's Wallach Hall residence hall is taking part as a pilot site for new low-flush toilets.
