Sewage is the liquid containing wastes/ liquid waste removed from the houses, factories, workshops, surface run-off water and agriculture. It is dark in colour and contains human faeces, urine, soaps, oils, grease, germs, chemicals, paints etc. These are called water pollutants or contaminants
Use jute or cloth bags instead of polythene bags. Do not throw the waste food items on plastic bags. Do not burn the plastics. Try to reuse many a time or let it recycle by selling plastic items no longer in use. Awareness programmes about minimum use of plastic should be organized and particularly their throwing here and there should be stopped.
