An investigation of water conservation during the construction of housing projects in Cape Town, South Africa

Abstract

Water scarcity poses a critical challenge to sustainable development, particularly in regions grappling with its profound implications. In response to this challenge, this study undertook an in-depth exploration into water conservation practices during the construction of housing projects in Cape Town, South Africa. The primary objective was to identify solutions that could alleviate the strain on freshwater resources within the construction industry. The investigation unfolded across various dimensions, from pinpointing reusable water applications to highlighting innovative practices and emphasising water-efficient methodologies. The study findings showcase a promising path forward. Reusable water, identified as a viable substitute in specific construction activities such as dust suppression, bricklaying and concrete curing, emerges as a key player in mitigating water consumption. The study champions the use of recycled water, affirming its practicality without compromising construction quality. Innovative solutions, including the adoption of curing agents and the implementation of grey water for non-potable uses, signify the industry's responsiveness to water scarcity challenges. The water-efficient practices embraced by the construction sector further underscore its commitment to sustainability. From recycled water usage to the implementation of misting and atomising systems for dust suppression, the industry has demonstrated a proactive stance. These practices not only reduce water wastage but also align with broader ecological goals. Crucially, this research extends beyond mere identification; it proposes a roadmap for the industry's future. Recommendations encompass educational initiatives, technological adoption and collaborative efforts to create a holistic approach to water conservation. By illuminating the nexus between responsible water management and construction practices, this study contributes to the evolving discourse on sustainable development, offering practical insights for not only Cape Town but also other regions facing similar water challenges.
