JAILCD2025-002: Addressing Jakarta’s Sinking Crisis Through Rainwater Harvesting System Integrated in Parking Facility A Regenerative Idea for East Senayan Parking Lot

Abstract

Jakarta faces significant urban challenges related to water management and environmental sustainability, necessitating alternative sources of water to address its ongoing crisis. With over half of Jakarta's population relying on groundwater, addressing these issues is critical. This research aims to explore design strategies for integrating rainwater harvesting systems within a multifunctional public-parking facility, forming a cohesive urban design to alleviate water crisis issues while offering an alternative water source for the city. Effective implementation of rainwater harvesting requires designs tailored to Jakarta's specific environmental conditions and urban landscape. Through several methodologies including literature reviews, precedent studies, and design explorations, various design strategies were identified, such as incorporating engaging water features into public spaces with multiple affordances and creating visual connections with the Gelora Bung Karno main stadium as the central landmark of the area. These findings demonstrate the potential of transforming underutilized but wide spaces like parking areas into regenerative urban nodes which support community engagement. By incorporating rainwater harvesting systems into these spaces, urban areas become more dynamic and responsive to both environmental and societal needs. This approach not only addresses Jakarta’s water crisis but also enhances public awareness of sustainable practices, promoting a more resilient and interconnected urban ecosystem. The integration of functional and community-centered solutions highlights the potential for sustainable transformation across the city’s urban fabric.
