Sewage collection network is one of the most important human inventions and today in most cities of the world, a sewage collection system has been set up whose task is to collect and transfer wastewater from homes and buildings to a wastewater treatment plant. The sewage network consists of large sewage pipes that are connected to each other to create a network through which sewage is transferred to the treatment plant.
In the past, when there was no sewage network, sewage wells were used to dispose of sewage. But now, with the advancement of technology, sewage wells are no longer used and the municipal sewage network has replaced it. By means of the sewage network, the produced wastewater can be transferred to the treatment plant and turned into safe water for nature.
What is sewage?
Sewage or effluent is waste water that is produced by humans or industry. This waste water sometimes contains waste materials that make this water unusable. But today, through some methods, these waters are treated and returned to the cycle of use. In general, there are two types of wastewater or effluent that can be treated.
Human wastewater
Sewage produced in residential buildings, which includes toilet, bathroom, kitchen, etc., is called human sewage, which contains human urine and feces and is usually excreted in sewage wells. Sewage is usually collected in sewage wells or special sources and, if necessary, is treated using wastewater treatment plants. Of course, there is an urban sewage network in some cities that uses sewage piping. It is transferred to a wastewater treatment plant outside the city and after the treatment process, the water is purified and produced for sanitary purposes for agriculture.
The necessity of collecting and treating human wastewater is its pollution. Therefore, to prevent the transmission of disease and increase pollution in cities, wastewater or effluent produced in cities is treated in a wastewater treatment plant. In addition to this issue, increasing the population and increasing the number of sewage wells should also be considered, which will cause major damage to nature and groundwater. In addition, it should be noted that more than 60% of water consumption in cities is converted into wastewater, and it is necessary to have a method that in addition to preventing the entry of this volume of wastewater into the environment, treat it and enter the cycle. Therefore, wastewater treatment plants were set up and a wastewater collection network was used to reach them.
So this invention has helped a lot in the field of plumbing in Toronto and the other cities.
