Non-revenue water  (NRW)  is  one  of  the  forms  of  water  loss.  There  is  a  tremendous  amount  of  NRW,  especially in developing countries. The real losses represent the more significant portion  of the NRW. These losses negatively affect the economy and formulate a barrier towards  reaching water sustainability. Therefore, the aim of the study was to that reduce NRW.  A systematic review was first conducted to find the relevant techniques and methods for  rehabilitating water distribution networks (WDN), which is one of the methods to reduce  NRW and to achieve the research aim which is reducing the NRW, after identifying the  WDN  rehabilitation  approaches,  a  questionnaire  survey  in  Malaysia  and  Egypt  was  carried through five months period from June 2020 to October 2020. The main aim of the  questionnaire survey was to identify cost-effective enhancement approaches. A total of  109  respondents from Malaysia and 67 respondents from Egypt, which means a total of  176 respondents were collected and analyzed. The sample size is suitable as most of the  targeted population  are  among the managers  and project managers with at least three  years of experience in the WDN field. The population was determined based on the top  companies and water authorities as the research focuses on advanced WDN rehabilitation  enhancement approaches. Then, Cronbach’s alpha, mean score ranking, normalization  value, and agreement analysis were carried in the data analysis phase. The results show  that  cost-effective  enhancement  approaches  are  programming,  models,  supervisory  control  and  data  acquisition  (SCADA),  and  twin  digital.  Additionally,  the  data  from  Malaysia suggest two more cost-effective enhancement approaches: zoning network and  genetic  algorithm.  These  two  techniques  might  possess  great  potential  for  other  developing  countries,  such  as  Egypt.  Then  finally,  after  identifying  the  cost-effective  approaches,  a comparison between the cost-effective approaches between Malaysia and  Egypt was done. Choosing the right technique can help industry practitioners maximize  the  benefits  of  WDN  rehabilitation.  The  comparison  would  help  the  researchers  and  industry  participants  to  adopt  and  further  develop  the  suggested  approaches.  The  discussion of the WDN enhancement rehabilitation approaches can help in adapting them  from other countries in the future. Proper WDN rehabilitation supports NRW reduction,  which  mainly  helps  move  towards  sustainable  water  management  in  developing  countries.
