Analysis of Water Loss Management Performance of Water Utilities and Development of Basic Performance Indicator Analysis Tool

Öz

In water loss management, monitoring system behavior and analyzing system performance according to appropriate indicators is very important for improving operating conditions. However, appropriate calculation tools should be used to make these analyzes accurately, regularly, systematically and precisely. Therefore, in this study, the most appropriate indicators were determined based on the indicators proposed IWA and other organizations in literature in order to analyze and monitor the process performance in water loss management. A web-based "GGS basic performance analysis calculation tool" has been developed to systematically calculate these indicators and monitor performance. This tool basically includes volumetric and percentage indicators, service connection and per line length indicators, administrative and physical loss, economic and cost, failure and network rehabilitation indicators. The details of this tool were detailed, its advantages were discussed by analyzing of sample data set. It is believed that this analysis tool developed in this study will provide significant contributions to the analysis and monitoring of the performance of the Utilities in terms of water loss management and its components, and to evaluate the process performance for active leakage control activities.

Su İdarelerinin Su Kayıp Yönetim Performansının Analizi ve Temel Performans Gösterge Hesaplama Aracının Geliştirilmesi

Öz

Su kayıp yönetiminde, sistem davranışının izlenmesi ve sistem performansının uygun göstergelere göre analiz edilmesi işletme koşullarının iyileştirilmesi açısından oldukça önemlidir. Ancak bu analizlerin doğru, düzenli, sistematik ve hassas bir şekilde yapılması için uygun hesaplama araçlarının kullanılması gerekir. Bu nedenle, bu çalışmada kentsel su kayıp yönetiminde su kayıpları ile mücadelede süreç performansının analiz edilmesi ve izlenmesi amacıyla literatür esas alınarak en uygun göstergeler belirlenmiştir. Bu göstergelerin belirlenmesinde Uluslararası Su Birliği (IWA) ve diğer kuruluşlar tarafından önerilen göstergeler detaylı bir şekilde analiz edilmiş ve su kayıp yönetimi açısından en uygun göstergelerin seçilmiştir. Belirlenen bu performans göstergelerinin sistematik bir şekilde hesaplanması ve performansın izlenmesi için web tabanlı “GGS temel performans analizi hesaplama aracı” geliştirilmiştir. Bu hesaplama aracı temel olarak, hacimsel ve yüzdesel göstergeleri, servis bağlantı ve hat uzunluğu başına göstergeleri, idari ve fiziki kayıp, ekonomik ve maliyet, arıza ve şebeke rehabilitasyon göstergelerini içermektedir. Bu hesaplama aracının detayları paylaşılmış, sağladığı avantajlar tartışılmış ve örnek veriler için analiz yapılmıştır. Geliştirilen bu hesaplama aracının, İdarelerin su kayıp yönetimi ve bileşenleri açısından performansının analiz edilmesi, izlenmesi ve aktif kaçak kontrolü faaliyetleri için süreç performansının değerlendirilmesinde önemli katkılar sağlayacağı düşünülmektedir.
