Sewage procedure (or domestic wastewater treatment method, municipal wastewater treatment) is often a kind of wastewater procedure which aims to remove contaminants from sewage to generate an effluent that is certainly appropriate to discharge into the encompassing atmosphere or an supposed reuse application, therefore preventing drinking water pollution from Uncooked sewage discharges.[5] Sewage incorporates wastewater from homes and companies And perhaps pre-handled industrial wastewater. You'll find a high variety of sewage treatment processes to pick from. These can range from decentralized systems (together with on-web site procedure systems) to huge centralized systems involving a community of pipes and pump stations (termed sewerage) which convey the sewage into a remedy plant.
Many historical towns had drainage systems, However they had been generally meant to have rainwater clear of roofs and pavements.
