Challenges in urban water management in the United States

The growing intensity of use of water in the urban environment of the United States is posing significant challenges for its supply, utilization, and protection. The development of traditional water sources is becoming more difficult, and water suppliers are turning to conservation and reuse as alternatives. Price disincentives and better water use management are being utilized to attempt to deal with limited capacity for distribution of water in periods of high demand. Urban runoff presents significant localized flooding problems. Management of floods and floodplains is given focus under the National Flood Insurance Act of 1968, which has as its goal the deterrence of development in flood-prone areas. Water quality goals, being developed and pursued under the Safe Drinking Water Act of 1974, are becoming more encompassing as the breadth of pollutants identified in the urban environment expands. Wastewater control strategies developed under the Federal Water Pollution Control Act of 1972 are expanding their emphasis upon nonpoint source pollution, as opposed to traditional emphasis upon point source pollution. Integrated management of the water resource will become increasingly necessary to adequately address water problems in the urban environment. State and local responsibilities for urban water management and control will likely increase.
