Abstract:

 Water is becoming more valuable every day in todays world, where the effects of the growing global population and global warming are increasing, and existing water resources continue to deplete. The inadequacies in water resources are causing problems for the environment and all living beings. Therefore, protecting existing water resources or creating alternative sources has become necessary. Rainwater harvesting is effective method for generating an alternative water source. In this study, the monthly and annual water storage potentials of the buildings in Bursa Uludağ University Faculty of Agriculture were determined by using the rainwater harvesting method, and the rates of meeting the need were calculated in two different scenarios, namely irrigation of the lawn area in the faculty and meeting the amount of water needed in the buildings, and the aim was to determine the amount of economic gain to be obtained. As a result of the study, it was determined that the rainwater harvesting method has an annual water collection potential of 2045.16 m3. With the installation of the system, it was concluded that an annual economic gain of 76858 TL was achieved in the faculty and that the initial investment costs of the system were amortized over 15.4 years.

 Su, dünya nüfusunun ve küresel ısınmanın etkilerinin giderek arttığı ve mevcut su kaynaklarının yok olmaya devam ettiği günümüzde kıymetini her geçen gün arttırmaktadır. Su kaynaklarında yaşanan yetersizlikler çevre ve tüm canlılar için sorunlar ortaya çıkarmaktadır. Bu nedenle mevcut su kaynaklarının korunması veya alternatif kaynaklar yaratılması zorunlu hale gelmiştir. Yağmur suyu hasadı, alternatif bir su kaynağı oluşturmak için etkili bir yöntemdir. Bu çalışmada yağmur suyu hasadı yöntemi ile Bursa Uludağ Üniversitesi Ziraat Fakültesinde bulunan binaların aylık ve yıllık olarak su depolama potansiyelleri belirlenerek, fakültede bulunan çim alanın sulanması ve binalarda ihtiyaç duyulan su miktarının karşılanması olmak üzere iki farklı senaryoda ihtiyacın karşılanma oranları hesaplanmış ve elde edilecek ekonomik kazanç miktarının belirlenmesi amaçlanmıştır. Çalışma sonucunda, yağmur suyu hasadı yöntemi ile 2045.16 m3lük yıllık su toplama potansiyeline sahip olduğu belirlenmiştir. Sistemin kurulumu ile birlikte fakültede yıllık olarak 76858 Türk LirasıTL ekonomik kazanç elde edildiği ve sistemin ilk yatırım maliyetlerinin 15.4 yıllık bir sürede amorti edildiği sonucuna varılmıştır.
