Quantities of wastewater

  1. Think about how often per month you are doing certain activities at home: taking a bath, washing dishes, washing laundry. Distribute the worksheet “How much sewage water do we produce?” among pupils. Let them observe their habits and complete the task within one week.
  2. Calculate how much water you use per day, per month, per year. Compare your results with the Danube average. (Danube average 120 l/day/person)
  3. Think about what happens with all this wastewater. How much of it is purified in water treatment plants, and how much of it remains as a burden for nature, to be purified in self-purification processes in aquatic systems? Try to get some information from your local wastewater treatment plant!
  4. Daily activities can use a lot of water, which is a limited resource. Think about what can be done to reduce the amount of water we use. There are simple things we can do, such as turning off the tap when brushing our teeth, taking shorter showers, collecting rainwater for watering plants, etc. By wasting less water, we can save energy and conserve natural resources.
