Answers
Various disposal pipes are required in streets because after heavy rain is found that water is logged in various streets of the city and the drain water even comes up so to avoid this pipes are built for passing this water out through various channels.
If there were no pipes then the water would have come up to knee length after heavy rain and thus it would have been a big problem for transport and communication. Various diseases may spread like cholera and typhoid as drain water comes up and so these pipes may help to resolve this.
There are separate pipes for disposing sewage and storm water because storm water infiltration into wastewater system can cause sewage overflow, which may lead to several environmental damages.
