Determination of Optimum Storage Method in Rainwater Harvesting: Karabuk University Social Life Center Example

Abstract

Rainwater harvesting (YST) system is a method of collecting rainwater and storing this free rainwater before reuse for a specific purpose. This system is widely used in most regions of the world that are suitable for local climatic conditions. Application of rainwater collection systems at optimum cost and design with low payback period is important for the sustainability and preferability of the system. In this study, the appropriate tank size was calculated for the rainwater harvesting system (YST) design process for the rainwater harvesting that can be obtained from the square and roof of the Karabük University Social Life Center, which has a hard floor and roof surface in the high area. Based on the scenarios designed by taking the existing warehouse volume of the university into consideration, the optimum storage method was decided for the YST system to be installed, considering the construction and warehouse costs. The study is expected to guide system builders and decision makers in the process of determining the warehouse quantity and storage method, which are the preliminary processes in YST system design.

Yağmur Suyu Toplama Sistemlerinde Optimum Depolama Yönteminin Belirlenmesi: Karabük Üniversitesi Sosyal Yaşam Merkezi Örneği

Abstract

Yağmur suyu toplama (YST) sistemi, yağmur suyunu toplama ve bu serbest yağmur suyunu belirli bir amaç için tekrar kullanmadan önce depolama yöntemidir. Bu sistem, dünyadaki yerel iklim şartlarına uygun olan çoğu bölgede yaygın olarak kullanılmaktadır. Yağmur suyu toplama sistemlerinin optimum maliyetle uygulanması ve düşük geri ödeme süresiyle tasarlanması, sistemin sürdürülebilirliği ve tercih edilebilirliği açısından önemlidir. Bu çalışmada, yüksek alanda sert zemine ve çatı yüzeyine sahip olan Karabük Üniversitesi Sosyal Yaşam Merkezi’nin meydan ve çatısından elde edilebilecek yağmur suyu hasadı için yağmur suyu toplama sistemi (YST) tasarımı sürecinde uygun depo büyüklüğü hesaplanmıştır. Üniversitenin mevcut depo hacmi de göz önünde bulundurularak kurgulanan senaryolar üzerinden, kurulabilecek YST sistemi için inşaat ve depo maliyetleri göz önünde bulundurularak optimum depolama yöntemine karar verilmiştir. Çalışmanın YST sistem tasarımında ön süreç olan depo miktarı ve depolama yönteminin belirlenmesi aşamasında, sistem kurucularına ve karar vericilerine yol göstermesi beklenmektedir.
