Using discrete-event simulation to evaluate a new master plan for a sanitary infrastructure

Increasing population and changes in life style have caused the wastewater network to deteriorate while exceeding their designed capacities. The Ministry of Public Works (MPW) is planning on expanding the capacities of some treatment plants and demolishing and replacing others with new ones by 2045. To asses this expansion, the current wastewater network was analyzed and the amount of untreated sewage water that is dumped into the sea was taken into consideration. The current network is composed of twelve main pumping stations and four treatment plants. Using discrete-event simulation, the current and future situations were modeled and the outputs were compared. This gives us a valid base to give recommendations for this large infrastructure project.
