Question

Which pipes should be bigger-those used for sewage disposal or those used for storm water disposal? Why?

Answer 1

The pipe used for storm water disposal should be bigger, i.e., it should have large diameter. This is because, when it rains very heavily, large amount of water comes down in a short time. If the diameter of the pipe is small, water will overflow on the streets and may cause major health risks by contaminating drinking water supplies.
