Where does sewage go?
This is a vital issue to ask as city inhabitants in a country that is becoming increasingly urbanised and populous. When you flush your toilet at home or at work, the waste, water, toilet paper, and everything else in the toilet bowl are flushed down a line known as the sewer. It then either runs into a septic tank on the premises – either in the backyard or underground – or flows further out to join a bigger sewage pipe infrastructure operated by the municipality.
All about the System_
With the exception of big towns with sewage networks, sewage is handled on-site using septic tanks, not just in individual homes but also in societies and residential clusters. All of this waste enters the septic tank through the drains, where dense stuff settles at the bottom of the tank and liquid enters the soak away pit, where it percolates into the soil.
Other types of waste are collected along the route by the sewage lines that go out of residences and workplaces. This could be waste water from the kitchen (cooking, waste liquid food, as well as washing utensils), gardening water, mud and waste, soapy water and remnants from the bathrooms (shower area, as well as cleaning the bathrooms and/or washing clothes) and gardening water. All of this combines to generate sewage, which is transported through a network of collecting pipes known as sewerage pipes. Scum growth in septic tanks can choke the influent side of the tank, producing sewage overflow into the residence and a foul odour.
The path traced _
Sewerage pipes in major cities collect and convey sewage from individual establishments such as houses, offices, schools, buildings, parks, and gardens, as well as all other municipal facilities, to larger sewerage pipes, from which it travels a considerable distance to a treatment facility. This is a complicated network of pipe networks that methodically run beneath and above the earth. Some of the largest pipes are as long as automobiles and transmit an enormous amount of garbage gathered from vast swaths of countryside and urban populations.
The processes involved_
Most towns and cities have sewage treatment facilities, which are large processing units where wastewater is cleaned, harmful components are removed, and a water return flow is initiated. Because sewage containing a lot of germs, bacteria, and harmful material enters a plant, it must be treated properly and effectively to prevent humans from getting into touch with it.
Screening, aeration, sedimentation, and disinfection are all steps in the wastewater treatment process. Everything from solid debris, such as coins, plastic, jewellery, and other items that may have been unintentionally flushed, to nebulous biochemical waste is eliminated from the water in this manner.
A considerable number of chemicals is then poured into the wastewater to clean it up and remove all of these dangerous particles, as well as to disinfect it and kill as many bacteria as possible. This is a lengthy procedure that can take anywhere from 7 to 10 days before the water is ready to be put back into the system. The cleaned water is then slowly released back into local waterways such as rivers, streams, and, in coastal areas, the ocean, via another network of pipes. Treated water that is discharged into rivers eventually ends up in the ocean.
