Estimation des eaux usées urbaines et application de L’approche décisionnelle multicritère pour le choix d’un site de station d’épuration

Abstract

The dynamic urban growth of Ksar Boukhari, largely driven by population growth, has led to a physical expansion of the city. This growth has resulted in an increasing demand for urban infrastructure and services, as well as a significant rise in the volume of wastewater generated within the city. The substantial demographic increase in Ksar Boukhari has been a primary driver of this growth, with a population increase of over 1.6% over the past decade. However, this rapid growth has also led to a significant increase in the volume of wastewater generated in the city, rising from approximately 464,000 cubic meters per year in 2025 to over 690,000 cubic meters per year by 2050. This increase in wastewater necessitates prudent management to prevent environmental pollution and ensure public health. Prudent management of these elements is crucial to preserving the quality of life for residents, protecting the local environment, and promoting sustainable urban development. The application of a multicriteria analysis helps make informed and balanced decisions for the efficient management of wastewater, thereby contributing to the prosperous future of this rapidly growing city.
