A water distribution network in an urban area in Muscat region (the capital city of Oman) is assessed for operational performance
using the widely accepted methodology proposed by the International Water Association (IWA). The technical performance
of this network was assessed using global performance index methods after modifying the performance levels as per local
guidelines. A total of 37 operational performance indicators for the network were selected to carry out assessment. Overall
operational performance showed high scores whereas some indicators showed unacceptable performance values. The network
showed very high technical performance considering nodal pressures. The lower performance for pipe velocity may be
attributed to the fact that the network is currently being utilized by 70% of the population for which it was designed. The
residual chlorine levels were within the acceptable range of the Public Authority for Water (PAW), showing a very good performance
by virtue of water quality. This study will be useful for decision makers to assess the operational, technical and water
quality performance of urban networks and take actions for improvements.
