Reviving traditional stepwells and ancient water bodies can significantly alleviate Bengaluru's escalating water crisis, according to a statement by senior official Nayak. The approach has historical precedent in the city of Belagavi, which successfully relied on rejuvenated wells until the Hidkal Dam began supplying water.
Historical Success in Belagavi
Before the Hidkal Dam project ensured a steady water supply, Belagavi depended heavily on the Rakaskoppa reservoir and a network of restored ancient wells to meet its drinking water needs. Nayak highlighted that these wells, once revived, provided a reliable and sustainable source of water for the city's residents.
“The rejuvenation of ancient wells in Belagavi proved to be a practical solution during times of scarcity. It not only supplemented the water supply but also helped recharge groundwater levels,” Nayak said.
Current Water Crisis in Bengaluru
Bengaluru, one of India's fastest-growing metropolitan cities, faces acute water shortages, particularly during summer months. Rapid urbanization and over-extraction of groundwater have exacerbated the crisis, leading to dried-up borewells and inadequate municipal supply. According to recent reports, the city requires about 1,450 million liters per day (MLD), but supply often falls short by 200-300 MLD.
Nayak emphasized that reviving ancient wells and stepwells, many of which have been neglected or encroached upon, could provide a decentralized and cost-effective solution. These structures historically served as community water sources and helped maintain the local water table.
Proposed Revival Plan
The official suggested a systematic survey of existing ancient wells across Bengaluru, followed by restoration and desilting. “Many of these wells are still structurally sound but filled with debris. With minimal investment, they can be brought back into use,” Nayak explained. He also called for involving local communities and resident welfare associations in the maintenance of these water bodies.
The plan aligns with the Karnataka government's broader initiatives to promote water conservation and recharge groundwater. Similar projects in other Indian cities, such as Chennai and Delhi, have shown promising results in augmenting local water supplies.
Environmental and Economic Benefits
Reviving ancient wells offers multiple benefits beyond water supply. It reduces dependence on energy-intensive pumping from distant reservoirs, lowers carbon footprint, and preserves cultural heritage. Economically, it is far cheaper than building new dams or desalination plants.
Nayak urged policymakers to prioritize this approach in Bengaluru's water management strategy. “We have a proven model from Belagavi. It's time to replicate it in Bengaluru to build resilience against water scarcity,” he concluded.
