This project focuses on the first phase of the Hussain Sagar Lake restoration initiative, emphasising stormwater management as a critical step toward reducing pollution and improving water quality in one of Hyderabad's most iconic water bodies. Hussain Sagar Lake has long suffered from severe pollution due to rapid urbanisation, inadequate infrastructure, and ineffective stormwater management systems. The project proposes implementing sustainable practices such as rainwater harvesting, bioswales, and infiltration basins in critical wards around the Balkapur Nala, a significant contributor to the lake's pollution. By targeting stormwater runoff, the project aims to mitigate flooding, reduce the inflow of pollutants, and enhance the lake's and surrounding areas' overall environmental health. In addition, the project includes educational initiatives designed to raise community awareness and involve residents and students in sustainable water management practices. This phase lays the groundwork for future actions, including wastewater treatment improvements, making the restoration efforts more effective and sustainable. The project also incorporates a life cycle sustainability analysis to evaluate how stormwater management systems can serve as a sustainable approach for treating the wastewater entering Hussain Sagar Lake. The project's anticipated outcomes include significant environmental, community, and economic benefits, contributing to a healthier urban ecosystem.
