6.2.1 Water consumption tracking

Bogazici University Water Use Measurement and Management Applications

Boğaziçi University effectively measures and manages water use across the entire campus. The University uses the mains water of ISKI (Istanbul Metropolitan Municipality's ISKI) as a water source and also makes use of the water obtained from the grey water recycling system and rainwater recycling systems.

In 2011, water footprint monitoring studies were initiated and water consumption was monitored in certain buildings using SoFi software. Thanks to this software, the environmental performance of each building is measured on a monthly basis and focal points that need to be improved within the campus are identified. Mains water consumption can also be monitored at a general level using ISKI consumption information.

At Boğaziçi University, grey water recovery system is used in two dormitory buildings. These systems, installed in South Campus 1st Male Dormitory and North Campus 4th Dormitory, recover 16 m³ of grey water per day. In addition, rainwater recovery systems installed at the Kandilli Campus National Earthquake Monitoring Centre (UDIM) and the North Campus ETA Building recycle water collected for garden irrigation, cleaning and reservoirs.

These systems represent important steps towards reducing water consumption and optimising water use in line with the University's environmental sustainability goals.

Clean Water and Sanitation

Boğaziçi University effectively measures and manages water consumption across the entire campus. The University uses water from the mains of ISKI (Istanbul Metropolitan Municipality) as a water source and also benefits from the grey water recycling system and rainwater recycling systems.

Water consumption in campus buildings depends largely on the intended use of the buildings. Factors such as areas used 24/7, student mobility and the presence of wet areas directly affect water consumption. Among all buildings on campus, dormitories have the largest share in water consumption. This is followed by buildings with high class capacities and high daily student density.

In 2011, water footprint monitoring studies were initiated and water consumption in certain buildings was monitored using SoFi software. Thanks to this software, the environmental and economic performance of each building is measured on a monthly basis and focal points that need to be improved within the campus are identified. Mains water consumption can also be monitored at a general level using ISKI consumption information.
