Definition - What does Collection System mean?
A collection system, as it pertains to sewer systems, is a sanitary collection system responsible for gathering and transporting wastewater from residential, commercial and industrial buildings to municipal treatment plants for treatment and eventual discharge.
Pipelines, lift stations, pump stations, and manholes are just some of the components that make up collection systems.
Trenchlesspedia explains Collection System
There are three primary types of collection systems. These are:
Sanitary Collection Systems
Sanitary systems collect wastewater, usually sewage, from residential, commercial or industrial sources. The waste from sanitary collection systems is sent to sewage treatment plants where it is treated before being discharged into natural waterways. Most industrial plants have their own treatment plants to deal with potentially hazardous waste.
Stormwater Collection Systems
Stormwater systems only collect water generated from rainwater or snowmelt runoff. The collected water is typically discharged to natural water courses without the need for treatment.
Combination Collection Systems
Combination systems perform the functions of both sanitary and stormwater collection systems. These systems are no longer used in modern communities, however, they can still be found in older cities. Wastewater from combined collection systems is conveyed to a treatment plant prior to discharge into waterways.
