Water Conservation and Smart Growth in Texas
As states face annual droughts and water use continues to grow in order to meet population and production demands, water conservation is essential to protecting natural resources and long-term reliance. Over the years, conserving water has become more necessary as the world’s natural resources continue to be strained in order to meet needs. As a result, water conservation consultants have filled an essential niche in resource management. Eddie Wilcut, the Water & Energy Efficiency Practice Leader at Plummer , started his career in the Air Force, where he took some classes focusing on water resources. In those classes, Wilcut read Aldo Leopold’s “A Sand County Almanac,” and a specific line has stuck with him for the past 26 years.
