Abstract

Kentsel su yönetiminde arıza yoğunluğuna bağlı olarak işletme koşulları bozulmaktadır. Arızaların oluşmasında en önemli faktör sistemdeki yüksek basınç ve basınçtaki düzensizliktir. Bu nedenle yeni arıza oluşumunun azaltılması için basıncın kontrol altına alınması ve dalgalanmaların azaltılması gerekmektedir. Ancak basınç kontrolü oldukça kapsamlı saha çalışması gerektiren, maliyetli bir süreçtir. Bu nedenle basınç yönetimi uygulanmadan önce oluşacak maliyetler (ekipman, saha çalışmaları, kurulum) ve faydalar (sisteme kazandırılacak potansiyel su hacmi, arızadaki potansiyel azalmalar) analiz edilmelidir. Bu çalışmada bir izole bölgede basınç yönetimi uygulanması durumunda ortaya çıkan maliyetlerin ve faydaların analiz edilmesi için hesaplama aracının geliştirilmesi amaçlanmıştır. Bu amaçla saha verilerine göre maliyet bileşenleri tanımlanmıştır. Ayrıca literatürde önerilen yaklaşımlar esas alınarak basınç kontrolüne bağlı olarak sızıntı ve arıza oranındaki azalmalar analiz edilmektedir. Bu fayda ve maliyet bileşenleri geliştirilen hesaplama aracına tanımlanmıştır. Geliştirilen bu hesaplama aracının özellikle uygulayıcılar için referans teşkil edeceği düşünülmektedir. Bu hesaplama aracında izole bölge çalışmaları için de fayda maliyet bileşenleri tanımlanmıştır.

Development of Cost-Benefit Analysis Calculation Tool for Pressure Control in Urban Water Management

Abstract

Operating conditions deteriorate depending on the density of failures in urban water management. The most important factor in the occurrence of failures is the high pressure in the system and the fluctuation in the pressure. Therefore, it is necessary to control the pressure and reduce the fluctuations in order to reduce the occurrence of new faults. However, pressure control is a costly process that requires extensive fieldwork. Therefore, before applying pressure management, the costs (equipment, field works, and installation) and benefits (potential water volume to be added to the system, potential reductions in failure) should be considered. The aim of this study is to develop a calculation tool to analyse the costs and benefits of applying pressure management in an isolated zone. For this purpose, cost components were defined according to field data. In addition, based on the approaches suggested in the literature, reductions in leakage and failure rates due to pressure control are determined. These fault and cost components are defined in the developed calculation tool. It is thought that this developed calculation tool will be a reference especially for practitioners. In this calculation tool, cost-benefit components are also defined for isolated site studies.
