The suggested procedures to ensure the prevention of any pollution occurring on campus are outlined in the water conservation policy. Additionally, the Engineering Unit does recurrent studies at two water outputs in conjunction with the university general chemistry lab. The primary water source is the first exit, while the water from the tanks holding treated water is the second.  For the water coming from the primary water source (the national water grid) and the recharging wells, the aforementioned tests are carried out every two weeks. The water from the tanks that provide the buildings with water is subjected to the same tests once a week.
