SUSTAINABLE WATER MANAGEMENT: THE ROLE OF UNIVERSITY CAMPUSES AND COMPARATIVE IMPLEMENTATION APPROACH

Considering the effects of increasing population, excessive urbanization and climate change,

the amount of rainfall-induced surface runoff, peak flows and pollution loads have increased

significantly as a result of the increase in impervious surfaces, especially in urban areas. For

this reason, especially in recent decades, many methods and practices have been developed in

various parts of the world within the framework of sustainable city understanding (LID, WSUD,

IUWM, SuDS, BMP). Within the scope of this study, the above-mentioned methods are

explained and their similarities and differences are evaluated. The distinct terminology arises

from their respective geographic origins, such as LID in the USA, WSUD in Australia, and

SuDS in the UK. There are a wide variety of structural and non-structural applications of these

methods, but considering that the establishment of different systems for the whole city is quite

difficult in terms of both economics, functionality and management, practical applications are

proposed for university campuses, which occupy an important place in urban areas. Nonstructural measures such as raising awareness of the public and administrators, cluster-type

settlement formation and protection of natural habitat should be considered as the first stage. In

the second stage, stormwater harvesting systems, rain gardens, green roof systems, permeable

pavements and car parks, and the design of university campuses are considered as basic

practices for sustainable water management. As a result of the cluster-type settlement, a

significant part of the land maintains the natural water cycle, while in the settlements within the

campus where construction is concentrated, structural applications reduce the amount of surface

runoff, pollutant load, peak flow, and reduce the dependence on mains water by reusing

rainwater.
