In a significant step towards addressing the looming water supply crisis in Bandung City, a recent study has evaluated the feasibility of two reservoir projects in the Cikapundung watershed. The research, led by Cleon Christopher from Universitas Katolik Parahyangan, highlights a pressing need for sustainable water management solutions as the city’s water demand is projected to reach 2.49 m³/s by 2040.
The study focuses on two potential reservoir locations—Cikawari 2A and Cikawari 5A—both situated along the same river. The analysis presents three construction alternatives: a standalone Cikawari 2A reservoir, a standalone Cikawari 5A reservoir, and a cascade system combining both. Each option offers distinct advantages and challenges, prompting a thorough evaluation to determine the most effective solution for the city’s future water needs.
“Our findings indicate that while the Cikawari 2A reservoir can supply 0.56 m³/s of water, it will only meet the needs of approximately 30.4% of the population in 2020, decreasing slightly to 30.15% by 2040,” Christopher explained. “Moreover, during dry periods, the reservoir’s output drops to 0.44 m³/s, revealing a significant gap between supply and demand.”
The implications of this research extend beyond environmental concerns; they resonate deeply within the construction sector. The necessity for additional infrastructure to bridge the water supply gap opens avenues for investment and development in the region. As cities like Bandung grapple with the dual challenges of population growth and climate variability, the construction of resilient water systems becomes paramount.
Christopher’s study underscores the urgency of innovative solutions in water management, suggesting that the construction of additional reservoirs or alternative water supply methods may be essential. The research published in ‘Jurnal Teknik Hidraulik’ (Hydraulic Engineering Journal) serves as a critical resource for policymakers and industry stakeholders, emphasizing the need for strategic planning in urban water resource management.
As the construction sector looks ahead, the findings from this study could influence future projects, potentially leading to a wave of infrastructure development aimed at ensuring water security for Bandung and similar urban areas. The intersection of environmental science and construction engineering is increasingly vital, revealing a landscape ripe for growth and innovation.
