CCWI2017: F122 'Comparison between Optimal and Real Design in Water Distribution Systems (WDS). Effect of Population Growth during the Project Lifespan.'

Urban processes affect Water Distribution Systems (WDS) and cause unsatisfactory operation, which violates the minimum pressure limit. For this reason, stablishing a valid rehabilitation criteria based on previous studies is necessary. In this paper a methodology to verify the results obtained by Specific Power and Resilience Index criteria is presented. The results obtained for six study cases in Colombia were analyzed in terms of costs, parameters and number of changes showing a reduction in costs and a reduced number of changes in the algorithm based on the second index.
