Performance Indicators for Monitoring Failure Maintenance and Repair Processes in Water Distribution Systems

Abstract

Failures in water networks cause problems such as water interruptions, decrease in network pressure, decrease in water quality, loss of water and energy, economic losses, traffic disruptions, and customer dissatisfaction. Detection, repair and system maintenance of failures due to various reasons are very important in terms of water loss management, economy of Water Administrations and ensuring sustainable water supply. Failure maintenance planning is a complex process that includes various alternatives such as rehabilitation and renewal, cleaning, maintenance-repair. The general purpose of this study is to detect the failures in water distribution systems with performance indicators and to monitor the breakdown maintenance and repair processes. For this purpose, in order to determine the performance indicators to be used in the study, first of all, a literature review was made and the performance indicators recommended for failure management by various institutions were obtained and performance indicator suggestions were presented for the solution of various problems within the scope of the study. A total of 18 indicators determined are grouped as basic, intermediate and advanced, taking into account their difficulty levels, needs and data structure. The study consists of the stages of determining the performance indicators, obtaining the necessary data for the indicators, performing the analysis and evaluation.. I was seen that the calculated indicators produce reference information in monitoring the failure performance and these indicators provide significant benefits in analyzing the gains obtained from the methods applied in reducing the failures.

İçmesuyu Dağıtım Sistemlerinde Arıza Bakım Onarım Süreçlerinin İzlenmesi için Performans Göstergeleri

Abstract

İçmesuyu şebekelerinde oluşan arızalar su kesintisi, şebeke basıncının düşmesi, su kalitesinin düşmesi, su ve enerji kaybı, ekonomik kayıplar, trafik aksaklıkları, müşteri memnuniyetsizlikleri gibi sorunlara neden olmaktadır. İçmesuyu dağıtım sistemlerinde çeşitli sebeplerle meydana gelen arızaların zamanında tespit edilmesi, onarılması ve sistem bakımının yapılması su kayıp yönetimi, Su İdarelerin ekonomisi ve sürdürülebilir su tedariğinin sağlanması açısından oldukça önem arz etmektedir. Arıza bakım planlamaları rehabilitasyon ve yenileme, temizleme, bakım-onarım gibi çeşitli alternatifleri içeren karmaşık bir süreçtir. Bu çalışmanın genel amacı, içmesuyu dağıtım sistemlerinde meydana gelen arızaların performans göstergeleri ile tespit edilmesi ve arıza bakım onarım süreçlerinin izlenmesinin sağlanmasıdır. Bu amaçla çalışmada kullanılacak olan performans göstergelerinin tespiti için öncelikle literatür taraması yapılmış ve çeşitli kurumlar tarafından arıza yönetimi için önerilen performans göstergeleri elde edilmiş ve çalışma kapsamında çeşitli sorunların çözümü için performans göstergesi önerileri sunulmuştur. Belirlenen 18 gösterge, zorluk düzeyleri, gereksinimleri ve veri yapısı dikkate alınarak temel, orta ve ileri seviye şeklinde gruplandırılmıştır. Çalışma performans göstergelerinin belirlenmesi, göstergeler için gerekli verilerin elde edilmesi, analizin yapılması ve değerlendirme aşamalarından oluşmaktadır. Çalışma sonucunda hesaplanan göstergelerin arıza performansının izlenmesinde referans bilgi ürettiği ve arızaların azaltılmasında uygulanan yöntemlerden elde edilen kazanımların analiz edilmesinde de bu göstergelerin önemli faydalar sağladığı görülmüştür.
