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 61 lift stations, 21 rain gauges and 206 metering sites.
The interceptor sewers range in size up to 14 feet in diameter.
