Revival of Hauz Khas Lake in Delhi: Approaches to Urban Water Resource Management in India

Abstract

<p>The decline of urban water bodies in India needs to be arrested for sustainable water management in rapidly expanding Indian cities. Reuse of water after partial recycling can reduce environmental stress. Delhi, the Indian capital, has a number of surviving water storage structures built by successive rulers over centuries to tackle water shortage in the summer. In modern Delhi, a fourteen million plus city, water is supplied through technological networks, hastening the decline of the old water storage structures. The old lakes are choked with filth and the step-wells are heaps of rubble. The Indian National Trust for Art and Cultural Heritage (INTACH) and the Delhi Development Authority (DDA) have undertaken a project to revive a 700 year-old water body, lying dry for decades, the Hauz Khas Lake, with treated sewage water. The idea was to raise the groundwater table and restore the natural environment of the lake, a past habitat for water birds. This paper attempts to evaluate the immediate impact and the long-term sustainability of the effort through discussions with technical personnel, field observations and interviews with local residents. Manuals and progress reports of the concerned organizations are used as secondary sources. The paper also examines the views of government officials and NGOs regarding the role of other similar projects in alleviating Delhi’s water shortage.</p>

Political Ecologies of Water Capture in an Indian ‘Smart City’

“…Alongside an improved groundwater balance, the Hauz Khas Lake Restoration Project has reportedly improved the biodiversity and utility of the landscape. Now that the lake is restored, observers have spotted previously unseen creatures such as bill ducks, pochards, mallards, shovelers, grebes, gadwall goose, and black-winged stilts and pintail ducks (Roy 2016;Singh and Bhatnagar 2012). The presence of these birds has added further appeal to the park surrounding the lake, resulting in a rise of visitors who can be seen walking, jogging, socialising, and even doing yoga (Roy 2016: 76).…”

Revival and Rejuvenation Strategy of Water Bodies in a Metropolitan City: A Case Study of Najafgarh Lake, Delhi, India.

“…These days households are supplied water through technological networks leading to the decline of the old water storage structures (Roy, 2016). These facts when viewed along with a decrease in availability of water resources point to a systemic flaw that can be tackled in a manner of ways.…”

“…Treated water was taken from a nearby Sewage Treatment Plant (STP), cleaned further through biological processes, and was transported to the dry lake (Roy, 2016).…”
