The institute has 2 septic tanks in which each tank is connected to an aerated lagoon. It is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewater by using aerators to mix the contents and add oxygen to the pond. It is an efficient and cost-effective system for primary and secondary wastewater treatment, low maintenance, and reliable treatment. Treated water is collected in many reservoirs in the institute and mix with rainwater from our drainage system again. Each reservoir also has aerators for oxygen adding to improve water quality. Treated water is used for watering the tree in the institute, and some of them are discharged into the public sewer.
