Integrated Urban Water Modelling

Modelling and data integration are powerful tools which municipalities can use to better understand and manage their wastewater systems, however, they have a substantial learning curve.  The Process Engineering Services (PES) section of eThekwini Water and Sanitation (EWS) has recently established a process modelling group with support from UKZN with the ambitious long term aim of developing an integrated model of the metro’s entire wastewater system, eventually including sewers, treatment works and rivers. Through the Water Research Commissions’  project C2021/2023-00628  a dedicated webpage for sharing data for urban wastewater systems, instructional materials, modelling tools and case studies. Modelling training sessions currently underway are focused on the use of Integrated Urban Water Systems (IUWS) model in WEST (DHI) and its adaption to South African conditions. This model can be used to predict and explore the interactions between weather, land use and drainage, sanitary and storm sewers, treatment works and receiving water quality. This website is still under construction and new training materials and topics will be added continuously as they become available.
