The self-cleansing velocity of water flowing through pipe lines, is
Oxidation: The organic matter present in sewage gets oxidized by the microorganisms with the help of dissolved oxygen present in river and results in formation of stable products.

See lessThe spacing of bars of perforations of fine screens used for the treatment of sewage, is
The bars used for screens are rectangular in cross section usually about 10 x 50 mm, placed with larger dimension parallel to the flow. Fine Screens: Fine screens are mechanically cleaned devices using perforated plates, woven wire cloth or very closely spaced bars with clear openings of less than 2Read more

See lessDepletion of ozone layer in the outer atmosphere may cause
A diminished ozone layer allows more UV radiation to reach the Earth's surface. For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain.

See lessInter-distance between ventilation columns in a sewer line is kept
Sewer ventilating columns are typically placed at regular intervals along the sewer line, often at a distance of 150 meters to 300 meters. This spacing helps to ensure adequate ventilation throughout the sewer system.
