Full Description

Over the next quarter century, water utilities in theUnited States will face a number of developments thatwill put pressure on their resources, spur them todevelop alternative supplies, and necessitate newapproaches to how they conduct business. This article,the second in a series, highlights two of these trends - population growth and climate change.The US population is predicted to reach 419 millionby the year 2050, an increase of 50%. Water demandswill skyrocket, stressing limited resources and requiringdevelopment of alternative sources. Furthermore, muchof this population growth will take place in regionsalready coping with water supply constraints. In addition,the population is aging, becoming more diverse inits ethnic makeup, and attaining higher levels of education - all factors that will affect how utilities communicatewith their customers.The next 25 years will also bring climate changethat will further test utilities. Wet years are likely tobecome wetter, and drought years more severe.Changes in flow patterns and stream levels could causeturbidity spikes and increases in contaminant concentrationsthat threaten regulatory compliance.Total water management offers an approach thatcan equip utilities to handle both expected developmentsand unpredictable events. Rather than tackleissues on a local level, total water management encouragesa more expansive worldview as well as cooperationand communication among communities, regulators,and institutions. Conservation, new technologies,and integrated resources planning - all hallmarks oftotal water management - will also assist waterproviders in meeting the challenges of growing demand and climate shifts.
