Wastewater refers to any water that has been used and contaminated in various ways such as from domestic, industrial, agricultural, or commercial activities. It is unsafe, unclean and polluted because it typically contains a variety of harmful pollutants including organic matter, pathogens, chemicals and nutrients. That is why treating your wastewater before releasing it into the environment is crucial for protecting our environment and public health. By treating wastewater, remove these pollutants and ensure that the water we release back into the environment is clean and safe. This helps prevent spread of diseases, protects aquatic habitats, and ensures water security. In short, treating wastewater is essential for maintaining a healthier and sustainable planet for current and future generations.
