SDGs Center UNAIR - Because of the enormous number of water uses at Airlangga University, the facilities and infrastructure department has taken steps to recycle and reuse the water that has been utilized. The remaining water is recycled from the ablution water on campus area B and C. 

The ablution water from the Ulul Azmi Mosque on Campus C is collected and reused in a reservoir. Similarly, the remaining ablution water on campus B, specifically at the Airlangga University Library, is accommodated.

Every day, about 20 cubic meters of water are collected, treated, and utilized to water plants and flush toilets. Before being recycled, the collected water is deposited. The leftover water will next be treated with the Sewage Treatment Plant (STP) System, which includes seven processes: storage and solids separator, precipitating tub, anaerobic chamber, aerobic chamber, sedimentation chamber, disinfection chamber / chlorination box, and release chamber.
