Japanese Tech Revives Dying Lakes in India
25 May
Summary
- Japanese technology aids natural purification of Vasai-Virar's polluted lakes.
- Pilot project revives Satpala Lake, restoring fishing and bird habitats.
- Nature-based solutions aim to restore 184 lakes in the Vasai-Virar region.
A pilot project employing Japanese technology is spearheading the revival of lakes in India's Vasai-Virar region. Years of neglect had led to severe pollution from industrial effluents and sewage, causing ecological damage and drying up natural springs.
The Vasai-Virar City Municipal Corporation (VVCMC) commissioned a survey in 2022, identifying 122 polluted lakes out of 184. Satpala Lake in Virar West was selected for a pilot project using nature-based solutions for wastewater treatment, funded by the United Nations Development Programme and launched in March. This initiative utilizes natural purification methods before water enters the lake and includes natural embankments to prevent waste dumping.
This project has revitalized Satpala Lake, a 5.5-acre water body crucial for local livelihoods through fishing. Residents have reported a return to fishing and an increase in bird species, signaling a significant ecological recovery. The success of the Satpala Lake project, costing ₹2.46 crore, has prompted the VVCMC to plan similar restorations for four other heavily polluted lakes in the region.
