A SIMULATION-BASED EVALUATION FOR A STRATEGIC RESIDENTIAL WASTEWATER NETWORK MASTER PLAN

This paper provides a study for the current and prospective strategic wastewater infrastructure in an entire country. The new master plan will be implemented no later than the year 2045, including building new treatment plans and installing new pumping stations into the wastewater network. Because this project is of major investment, simulation modeling is necessary to predict the performance of the wastewater network included in the sewage master plan. The study covers forecasted demand, seasonality fluctuations, and rainfall effect and fits them to theoretical distributions. The model was statistically validated. The simulations revealed how the wastewater treatment plants (WWTP) and pumping stations will perform with respect to their capacities. The study aims to reduce wastewater dumping and achieve full utilization of treated effluent.
