Sewerage, or sewage network, is an umbrella term that encompasses a number of integral components.
The sources of sewer water are wastewater or sewage which include domestic wastewater, industrial or technological wastewater, agricultural wastewater, municipal wastewater, external water, and precipitation (meteoric) water. These waters differ in terms of pollution, the amount of runoff and the change in the size of the runoff.
The wastewater is collected and discharged: by using gravity sewerage system, by pumping, by using negative pressure – vacuum discharge and pressure discharge.
The sewage systems thus include pumping stations to discharge water. Pumping stations are facilities for pumping water into the sewage system, septic tanks and cleaning plants, and are intended for pumping industrial wastewater and domestic wastewater from detached houses, business facilities, farms, agricultural facilities, holiday houses etc.
