Abstract

Industrial wastewater management remained a big challenge for developing countries. Industries directly discharged their effluents into the natural drains, sewer system, internal septic tank, and nearby fields. Recent urbanization and industrial activities have led to environmental deterioration, creating complex environmental conditions and health hazards. This study aims to propose a suitable site for the construction of a wastewater treatment plant (WWTP) in the Landhi Industrial Estate (LIE) of Karachi, using Weighted Overlay Analysis (WOA). Four selection criteria were considered in for this analysis: road network, a slope, surface water, and land use/land covers. Weights were assigned for each criterion to find a suitable site. The two suitable sites are selected according to the suitability criteria.
