Abstract:

This study evaluates water resource management at the Artistic Milliners Unit 5 (AM-5) factory in Landhi, Karachi, under Alliance for Water Stewardship (AWS) standards through a WWF-commissioned assessment (Contract No: 137/Freshwater/24-25). It analyzed catchment delineation, aquifer characteristics, and rainfall trends from 1960–2023, highlighting increasing extreme weather events and vulnerabilities in local water infrastructure, with findings revealing an annual water shortfall of 6.49 MCM alongside challenges such as groundwater depletion, high salinity, and unreliable municipal supply. Despite these constraints, AM-5 adopts a hybrid water strategy integrating recycled water and reverse osmosis treatment to reduce freshwater dependency, while recommended mitigation measures include expanding wastewater recycling, adopting advanced treatment systems, and strengthening stakeholder collaboration to improve resilience. The study emphasizes the importance of integrated water stewardship in industrial zones and provides scalable recommendations to enhance urban water security amid climate variability and rising demand.
