The current sewer system utilizes stoneware pipes up to 300 millimetres (11.8 in) in diameter, and RCC pipes for the mains and outfalls up to 2,100 millimetres (82.7 in) in diameter. [12] There are three main sewage treatment plants, which are located in the Vrishabavathy, Koramangala-Chellaghatta and Hebbal valleys.
A comprehensive improvement to the city sewage system was designed in 1958 for an estimated 1976 population of 25.5 lakhs and 1991 population of 27.2 lakhs at a sewage flow rate of 110 lpcd in 1976 and 180 lpcd in 1991; the city was also divided into five zones with proposals for five independent disposal works.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

However, during rainstorms, the flow can exceed the capacity of the ...
