Aquatic ecosystems provide irreplaceable benefits; including water supplies; food for people and wildlife; water purification and filtration of pollutants; flood and drought mitigation; even recreational opportunities. As the economic and ecologic services provided by aquatic ecosystems gain more recognition and the deleterious effects of mismanaging water resources become more apparent; the global water community is taking steps toward ecologically sustainable water management. Because their operations have significant and far-reaching consequences for aquatic ecosystems; drink ing water providers can play a major role in safeguarding the health of these systems. Strategies to protect aquatic ecosystems include reducing water demand through conservation; managing water within the bounds of an ecological flow prescription; planning for ecosystem allocation during drought; and protecting source watersheds. With urban populations growing and water demands on the rise; utilities must act now to ensure that the benefits provided; by healthy aquatic ecosystems are available to future generations. - MPM;
