Investigation ​of Water Losses ​in Water Supply ​System - Muscat ​as a Case Study

One of the problems affecting water supply systems in Oman is the problem of water loss and Non-Revenue Water (NRW). The aim of this research is to carry out water auditing for Al Seeb water distribution network as a case study to estimate the water losses, NRW, water balance, and the resulting financial and operational impacts. Annual data on water supplies, water consumption, system data, and cost data for the years from 2010 to 2014 was collected from the Public Authority for Electricity and Water (PAEW) and the analysis was done using the American Water Works Association (AWWA) audit software to determine water losses including real and apparent losses, NRW, water balance, and the cost. The results indicated that the average of apparent loss, real loss, and NRW from 2010 to 2014 was approximately 19.5%, 21%, and 40 % respectively. It was estimated that the average annual cost of NRW between the years 2010 and 2014 was approximately 9.4 million USD, which was approximately 33% of the total revenue budget. In conclusion, there is a need for the development of water management systems to provide the best management practice system to further minimize NRW problems in Oman.

  1. The results of this investigation are to be treated with reserve as the writers have, despite fig 1, failed to fully understand the components of NRW. It fails to include water that has been billed but payment not received which, even in the developed nations usually exceeds 2%. Further, the 10% figure relates to 'leakage' which is only a component of NRW and hence not the same thing. Process losses appear to be ignored. To use the leakage figure as a  target for NRW as a whole is simply unrealistic. 20% for NRW in total is probably much better than will ever be achieved.

    1. d with you, he need to specify the various types to water losses and NRW. 

      The figures of these various components if relatives accurate will be calculated to determined the percentages of Commercial Losses, Technical, and Administrative losses for decision to reduces the Water Loss and NRW.

       

  3. please am in propose of writing a proposal for my Phd programme and my interest is on water demand management which i think i will understand the calculation of water lossess and NRW. 

    I THEREFORE WANT TO FIND OUT FROM YOU HOW O GET THE SOFTWARE FOR THE CALCULATION OF NRW.

    Thank you
