Distribution System Operations & Maintenance
The operation and maintenance of water distribution systems includes maintenance of water quality, system management programs, and operation and maintenance of facilities. Explore AWWA’s extensive manuals and standards on this topic to develop a complete program for the management, operation, and maintenance of a small, medium-sized, or large water distribution system.
Wastewater Collection Systems
Wastewater collections systems are comprised of gravity pipes, manholes, tanks, lift stations, control structures, and force mains that gather used water from residential and nonresidential customers and convey the flow to the wastewater treatment plant. It takes thousands of miles of pipeline to collect this wastewater so it can be treated and returned to the environment.
