Interceptor Conveyance

Interceptor system

Individual wastewater service connections are typically made to the local community sewer collection systems in the streets. The local community collection systems transport wastewater to service points, usually at the city border, where the wastewater is transferred into the Metropolitan Council Environmental Services (MCES) Interceptor system. The MCES Interceptor system meters and transports the wastewater flows to one of seven regional wastewater treatment plants. The MCES transportation system is comprised of over 600 miles of pipelines, over 70 pumping stations, 21 rain gauges and 188 metering sites.

The interceptor sewers range in size up to 14 feet in diameter.

In addition to operating lift stations and maintaining the extensive conveyance system,lift stations, rain gauge stations, and flow meters MCES manages an Inflow and Infiltration program as part of the Water Resources Management Policy Plan.

Inflow and infiltration is clear water that enters the sewer system from a variety of sources.  Infiltration occurs when ground-water seeps into sewer pipes through cracks, leaky pipe joints and/or deteriorated manholes, where inflow occurs through rainfall/storm water that enters the wastewater system.
