Waste water is the used water containing dissolved and undissolved waste from our kitchens, bathroom, laundry ect. Explain how water treatment works using the following words: sewage, septic tank, sewage treatment plant, effluent and storm sewers

Water treatment begins with the collection of waste water, which includes sewage from households and businesses, as well as storm water from rainfall that enters storm sewers. The waste water is then transported to a sewage treatment plant, where it undergoes a series of processes to remove contaminants and pollutants.

At the sewage treatment plant, the waste water is first screened to remove large debris and solid waste. It then goes through a settling process in a septic tank, where heavy solids settle to the bottom and are removed. The liquid waste, called effluent, is then treated further through biological and chemical processes to remove harmful bacteria, viruses, and other pollutants.

After treatment, the effluent is disinfected to kill any remaining pathogens before it is released back into the environment, such as rivers or oceans. This ensures that the water is safe to be re-used or returned to the natural water cycle.

Overall, water treatment plays a crucial role in maintaining clean and safe water sources for drinking, agriculture, and industry, while also protecting the environment from pollution and contamination.
