    1. Used oils and fats should not be poured into the sink which may choke the pipes. We should always throw oils and fats in the dustbin as in open drain the fats clog the soil pores and the filtration of water.
    2. Many household chemicals like paints, motor oil, insecticides, etc. should not be allowed to go down as these are very toxic and harmful to both humans and microbes.
    3. Used tealeaves, solid food remains, soft toys, cotton, sanitary towels, etc. should also be thrown in the dustbin which may choke the drains as it do not allow the free flow of oxygen and thus hamper the degradation process by microorganisms.
