Abstract

It is important to identify, reduce, prevent and control the water losses for sustainable urban water management and efficient use of resources in potable water distribution systems. Economic analysis should be made to decide on the method to be followed and the path to be followed in the struggle against water losses. In this study, in order to reduce water losses in water distribution systems, it is aimed to perform economic analysis for leakage management activities and network rehabilitation. For this purpose, Malatya province water distribution system was chosen as the application area. The return period of the investments for leakage management made in the regions without rehabilitation is calculated as 3-4 months. On the other hand, depending on the high initial investment cost in the rehabilitated areas, the return period of the investments was on average between 13-17 years. As it can be understood from these calculated return period of investments, network rehabilitation appears as a tool with high initial investment costs. For this reason, it is considered very important to make costbenefit analysis in determining, reducing, preventing and controlling water losses in a distribution system.

Özet

İçmesuyu dağıtım sistemlerinde su kayıplarının tespit edilmesi, azaltılması, önlenmesi ve kontrol edilmesi, kaynakların verimli bir şekilde kullanılması ve sürdürülebilir kentsel su yönetimi için oldukça önemlidir. Su kayıpları ile mücadelede uygulanacak yöntem ve izlenecek yola karar vermek için ekonomik analizin yapılması gerekmektedir. Bu çalışmada, içmesuyu dağıtım sistemlerinde su kayıplarının azaltılmasında, sızıntı yönetimi aktiviteleri ve şebeke rehabilitasyonu için ekonomik analizin gerçekleştirilmesi amaçlanmıştır. Bu amaçla Malatya ili merkez içmesuyu dağıtım sistemi uygulama alanı olarak seçilmiştir. Rehabilitasyon yapılmayan bölgelerde sızıntı yöntemi faaliyetleri için yapılan yatırımların geri dönüş süresi 3-4 ay hesaplanmıştır. Diğer taraftan rehabilitasyonu uygulanan bölgeler için yapılan bölgelerde ilk yatırım maliyetinin yüksek olmasına bağlı olarak geri dönüş süresi ortalama olarak 13-17 yıl arasında elde edilmiştir. Hesaplanan bu geri dönüş sürelerinden de anlaşılacağı üzere, şebeke rehabilitasyonu ilk yatırım maliyeti oldukça yüksek olan bir araç olarak karşımıza çıkmaktadır. Bu nedenle bir dağıtım sisteminde su kayıplarının tespit edilmesi, azaltılması, önlenmesi ve kontrol edilmesinde fayda maliyet analizlerinin yapılmasının oldukça önemli görülmektedir.
