Each month in 2022, WEF will focus on a particular topic within the water sector.

August's Focus: Collection Systems

The system of underground pipes and maintenance structures that convey wastewater to treatment are the first line of defense for public health. Whether they are sanitary sewers – carrying only was from households and commercial establishments – or combined sewers – carrying stormwater, too – these systems require careful design, construction, operation, and maintenance.

Urban and suburban stormwater runoff is a growing source of water pollution in many watersheds across the country, contributing nutrients, bacteria and sediment.  Further, the existing stormwater infrastructure is aging and underfunded.  Stormwater runoff is currently addressed through protection and water quality improvement strategies developed by utilities, municipalities, state governments and the US EPA.  However, the nation lacks a comprehensive uniform plan of action at the federal level to cohesively, economically and effectively mitigate stormwater runoff impacts to water quality. Further, funding for research and infrastructure is insufficient at all levels.
