Case studies

Boulder Water Utility

Due to its location in a semi-arid region, the city of Boulder faced both severe flooding and severe drought. To manage floodwaters and improve water supply and quality, the city built greenways and developed a comprehensive conservation plan for unusually dry seasons resulting in residential indoor and outdoor water savings averaging 5,000 gallons per household per year. In addition to addressing its local water challenges, Boulder’s creative strategy has also allowed it to realize multiple benefits including open space, new recreational opportunities and public education better connecting the community to nature.
