Municipal drinking water is produced from a variety of sources including fresh water, brackish water, and seawater supplies. Sufficient potable water supplies are required to support the growing demands imposed by human consumption and by industrial and agricultural activities. Increasingly, cutting-edge treatment technologies, such as membrane-based methods and advanced disinfection processes, are being used to meet tightening regulatory water quality requirements and to enable the development of new water sources from otherwise overlooked supplies.
Another trend that is being used to supplement potable water supplies is the increasing use of secondary and tertiary treated municipal wastewater as a water supply alternative for selected industrial applications and as recharge for groundwater supplies. (return)
