A natural drain becomes polluted due to the ingress of waste from septic tanks, discharge of untreated sewage & industrial waste and also solid waste dumping, which eventually contaminates and pollutes our rivers, lakes, and oceans. Most of the polluted drains are contaminated with pollutants like chemicals, oil, grease, and sewage.
Polluted and contaminated drains can pose a risk to human health, particularly if it comes into contact with skin or is ingested. It can also harm wildlife and aquatic plants by reducing the amount of dissolved oxygen in the water and making it difficult for them to survive.
