ITU as a body has a Water Management Directive , which protects water resources on the campus and prevents polluted water from entering the water system. In this way, water systems are not affected by any kind of failure. All infrastructures about stormwater
and wastewater are separated from each other. The whole generated wastewater is collected from the buildings and conveyed out of the campus. The collected wastewater is received by Baltalimanı Wastewater Treatment Plant which is operated by Istanbul
Water and Sewerage Administration. A screenshot and plan view was given showing the campus and Baltalimanı Wastewater Treatment Plant.
