Answer 1

pollution caused by sewage water is one of the major problems in cities the world over. sewage water is drained off into rivers without treatment. Careless disposal of sewage water leads to creation of a chain of problems like spreading of diseases, eutrophication, increase in Biological Oxygen Demand (BOD), etc.

because the sewage which contains harmful bacteria when gets mixed with water pollutes it and that is only used by farmers and other people for irrigation and other purposes which when utilized by us can cause many diseases.
