Recovering the depths of the past: using old stepwells for new water in India. From the article:
Plunging into the earth, stepwells like Chand Bawri were built in drought-prone regions of India to provide water all year round, ensuring communities had access to vital water storage and irrigation systems.
Centuries of natural decay and neglect, however, have pushed these structures into oblivion. Dating back more than 1,000 years, the stepwells (baoli, bawri, or vav) are crumbling into obscurity. Their value has gone largely unnoticed by town planners as modern running water systems eclipsed their importance. Many stepwells are in shambles or have caved in. Some have disappeared completely.
But in recent years, many of these ancient edifices are being restored to help tackle India’s acute water problem. The country is currently undergoing the worst water crisis in its history, according to a recent government report. There are hopes that the ancient technology of the stepwells might offer a solution….
The government emphasises the need to use India’s historic water management systems for solutions to these problems. States can leverage new technologies to modify traditional water systems for local requirements. In a nation where 600 million people – around half the population – face severe water shortages daily, traditional water-harvesting solutions are a harbinger of hope. “With India’s water table rapidly declining, stepwells can help refill ground aquifers and harvest runoffs. In three months during the rainy season, millions of litres of water can be collected,” says Ratish Nanda, a conservation architect and projects’ director at the Aga Khan Trust for Culture, an organisation leading restoration efforts….
Gram Bharati Samiti (Society for Rural Development), a non-profit in the Jaipur district of Rajasthan, has carried out restoration work of seven stepwells in the villages of Rajasthan, providing around 25,000 people with a more reliable water source.
“We have restored seven stepwells where ground water has been recharged and storage capacity has increased,” says Kusum Jain, secretary of Gram Bharati Samiti. “Most stepwells can provide ample water for the daily needs of the villagers. It saw a unique coming-in of volunteers from different communities, exemplifying India’s religious harmony.”…
Stepwells are multi-storied subterranean structures with significant ornamental and architectural features. They usually have two parts: a vertical shaft of water and the cascading galleries, chambers and a flight of orchestrated steps. “Stepwells are a repository of India’s historical tales, used for social gatherings and religious ceremonies,” says historian Rana Safvi. “They served as cool retreats for travellers as the temperature at the bottom was often five-six degrees lesser. Stepwells helped create bonhomie in common spaces as well as providing water for communities. They are an ingenious system for rainwater harvesting and served as water reservoirs. Revival of stepwells could be a significant step in our fight to overcome water shortage.”
