Yağmur Suyu Hasadının Ondokuz Mayıs Üniversitesi Kütüphane Binasında Uygulanabilirliğinin Araştırılması

Öz

Sınırlı su temini ve iklim değişikliği ile birlikte artan su ihtiyacı, küresel olarak suya erişim zorluklarını beraberinde getirmektedir. Artan su talebi ile sınırlı su kaynakları arasındaki dengesizliği gidermek için sürdürülebilir su yönetim sistemlerine ihtiyaç vardır. Yenilenebilir bir kaynak olarak yağmur suyu, bu amaca ulaşılması için büyük bir potansiyel sunmaktadır. Bu çalışma, önemli bir sürdürülebilir su yönetimi stratejisi olan yağmur suyu hasadı (YSH) na odaklanmaktadır ve YSH'nın üniversite ölçeğinde dış mekan sulama talebini karşılama kapasitesini değerlendirmeyi hedeflemektedir. Bu kapsamda 3017 m2 çatı alanı olan Ondokuz Mayıs Üniversitesi Merkez Kütüphanesi binasına uygulanacak YSH sisteminin sulama amaçlı kullanım kapasitesi hesaplanmıştır. Yıllık 1754 m3 yağmur suyunun kütüphane çatısından sağlanabileceği, yıllık 5186 m3 yıllık su ihtiyacının bu yağmur suyundan karşılanabileceği, bu hesaba göre Kütüphane binasının çevresinde bulunan ekilebilir alanlar ve seralar için gerekli olan yıllık su ihtiyacının %33,8 inin yağmur suyu hasadı ile sağlanabileceği bulunmuştur. Yapılan maliyet analizine göre toplam 362875 TL ekipman maliyeti sistemin çalışması durumunda 8,7 yıl içerisinde geri ödeme sağlamış olacaktır. Çalışma sonuçlarına paralel olarak Yağmur suyu hasadı kentsel su yönetimi, güvenli su arzı ve sürdürülebilir su planlaması için önemli derecede katkı sağlamaktadır; bu nedenle devlet kurumları ve yerel yönetimler tarafından gerekli desteğin sağlanması önerilmektedir.

Investigation of the Applicability of Rainwater Harvesting in Ondokuz Mayıs University Library Building

Abstract

Limited water supply and increasing water demand with climate change bring along the challenges of accessing water globally. Sustainable water direction systems are required to address the imbalance between increasing water demand and restricted water resources. As a renewable resource, rainwater offers great potential to achieve this goal. This study focus on rainwater harvesting (RWH), an important sustainable water direction strategy, and aims to evaluate the capacity of RWH to meet outdoor irrigation demand at university scale. In this context, the irrigation capacity of the RWH system to be applied to the Ondokuz Mayıs University Central Library building, which has a roof area of 3017 m2, has been calculated. It has been found that 1754 m3 of rain water per year can be obtained from the roof of the library, that the annual water need of 5186 m3 can be met from this rainwater, and according to this calculation, 33.8% of the annual water need for the arable fields and greenhouses around the Library building can be met by rainwater harvesting. According to the cost analysis, a total equipment cost of 362875 TL will be paid back in 8.7 years if the system works. In parallel with the results of the study, rainwater harvesting makes a significant contribution to urban water management, safe water supply and sustainable water planning; for this reason, it is recommended to provide the necessary support by state institutions and local administrations.
