Wastewater Collection Systems

Page Content

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.
