Huachiew Chalermprakiet University has an aerated wastewater treatment system.  According to the wastewater treatment system operation plan, some amount of chlorine will be added to the treated wastewater in order to kill germs or remove harmful contaminants. Then it will be transferred and stored in the recycling wells before being pumped to be used for watering plants and lawns. The university will use 100% of all recycled water for watering the plants in the university.
