How Stormwater Harvesting Helps in Pollution Mitigation
Human actions and choices can go a long way in impacting our environment. Over the years of rapid urbanization, we had destroyed the natural ecosystem in cities. Due to the wide-spread jungle of concrete, stormwater management emerged as a challenge before the urbanites. The impervious surfaces not just interfered in the natural process of surface water recharging, but also became a major cause of waterlogging and water pollution. When stormwater passes through impervious surfaces, it carries away many pollutants and micro-nutrients. These pollutants are then deposited into the nearby water bodies, thereby degrading the water quality and disturbing the aquatic ecosystem. The pollution created by stormwater passing through impervious urban surfaces is called non-point source pollution and accounts for the largest source of water pollution. The major NPS pollutants include the following: Pesticides Motor vehicle contaminants Nutrient sediments Road salt Heavy metals ...
