Assessment of Factors Impacting Water Supply Services in Lusaka District: A Case of Lusaka Water Supply and Sanitation Company

Abstract

The water supply situation in Lusaka district faces numerous challenges related to reliability, accessibility, and sustainability of water supply services. Despite a population of 3,079,964, only 134,807 household connections were established by LWSC in 2022. With a record 4.5% population increase from 2022 to 2023, the demand for water stands at over 420,000 cubic meters per day, while LWSC produces 250,000 cubic meters per day. Groundwater, accounting for 57% of LWSC's water, is threatened by land development and pollution. Meanwhile, 45% of the population relies on site sanitation, contributing to groundwater pollution, the very source LWSC is dependent upon. Lusaka faces low or no water supply, an average of 18 hours per day. Despite existing research on the peri-urban water supply, a gap remains in addressing the challenges of rapidly growing urban areas like Lusaka. This study aims to fill this gap by providing a comprehensive analysis focusing on the unique challenges faced by LWSC, such as land development, population growth, and climate change. The research will offer practical solutions for sustainable water supply management in Lusaka and similar contexts. The research philosophy employed for this study is interpretivism, as it allows for a deep understanding of the subjective experiences and perceptions of experts involved in the water supply sector in Lusaka. This approach aligns with the qualitative nature of the research, which aims to explore and understand the complex interactions between various factors influencing water supply services in the district. The findings of the study reveal that climate change, population growth, and land development are significant factors influencing water supply services in Lusaka. Erratic rainfall patterns and prolonged droughts have led to challenges in water availability and quality, while rapid population growth has increased the demand for water supply services, putting pressure on the existing infrastructure. Unplanned land development has also led to challenges in water supply services, particularly in areas with shallow water tables that are vulnerable to groundwater pollution. The study recommends investing in climate-resilient infrastructure, diversifying water sources, enhancing water conservation practices, and strengthening land use planning regulations to address these challenges and ensure the sustainability of water supply services in Lusaka.
