My town has the problem of drainage system. it has many sewage canals but all are either blocked or have been destroyed due to harsh weather.
the sewage canals should be devloped properly and with strong material so that they can sustain some years . during the process of making canals logged sewage water should be disinfectant to avoid the breeding of mosquito and flies
