Bengaluru's Historic Water Management
Bengaluru's water management history dates back to the 1500s when the founder, Kempe Gauda, was advised by his mother to build lakes and preserve the fertile land. With the construction of numerous interconnected lakes and tanks, Bengaluru thrived on rainwater harvesting and community support. However, the British colonization marked a shift towards piped water networks, leading to the decline of natural water bodies for urban expansion. Today, Bengaluru faces a severe water crisis due to rapid population growth, groundwater exploitation, and the disappearance of historical lakes, necessitating sustainable solutions for water rejuvenation and conservation.
Phytoremediation and Water Rejuvenation Efforts
Efforts to revitalize Bengaluru's lakes include innovative approaches like phytoremediation, as seen in Hyderabad's Naiknampur lake revival. By purifying water through natural processes and directing treated water into lakes, authorities aim to replenish groundwater sources and improve water quality. The use of floating islands with soil and plants aids in absorbing pollutants from sewage water, serving as a natural purifier and promoting groundwater recharge. While such initiatives offer hope for long-term water sustainability, Bengaluru continues to grapple with immediate challenges and the unpredictable nature of monsoon replenishment.
