Urban Water

Studies indicate that the levels of infrastructure services available in urban regions in India are improving, however their quality is still debatable. This paper uses secondary data available from various government report to review the norms and standards for the following basic services

• Water supply
• Sewereage
• Solid waste management
• Primary education
• Preventive health care

In addition resource gaps and measures to bridge these gaps are also examined.

Bagmati river in Kathmandu: From holy river to unthinkable flowing filth

Ajaya Dixit initiated his presentation with a general account of how rivers shape the landscape and how riverine ecosystems have nurtured society and kept civilisations vibrant, cultured and creative. Dixit went on to discuss the basin characteristics of the Bagmati, a tributary of the Kosi that rises in the Shivapuri hills, north of the Kathmandu valley. Around fifteen percent of the basin area (3700 sqkm) lies in Nepal, while the remaining is in India. The average annual rainfall in the basin is 1400 mm and is more than 2000 mm in the hills. Bagmati is a seasonal river with rainfall and springs as its main source. Its mean flow is 15.6 cubic metre/second and low flow is 0.15 cubic metre/second in April.

Kathmandu lies in the Upper Bagmati basin and studies suggest that an ancient lake called the Paleo-Kathmandu lay within the Kathmandu valley as a lacustrine formation. Early settlers lived in lower slopes and used springs and river in the upper reaches. When they moved to the valley floor, they built dongia dharas, which are stone water spouts fed by the unconfined aquifers and delivered water through surface channels. Even today, dongia dharas dated back to 1500 years exist. The state built canals (raj kulo) tapped the upper stretches of the rivers close to the mountains. Rivers and irrigation helped recharge aquifers and ponds.

However, rising urbanisation has damaged these ancient artifacts. Over the last sixty years Kathmandu has expanded massively and its population has increased from 0.41 million in 1951 to 2.6 million in 2011. The city has a huge transient population aside from this, reducing it to a concrete nightmare. Seismologists suggest that Kathmandu is a rubble city in the making. Though the Bagmati river flow has not changed significantly in the last seventy years, the character of the river has been transformed significantly during the period 1970 to 1990. The river has been canalised while the dumping of the city’s garbage into it continues. Dixit identified a plethora of problems faced by the river such as upstream water diversion for drinking water needs, disposal of untreated liquid waste, disposal of solid waste, river jacketing for roads and commercial activities, sand mining and physical encroachment.

The state of the river is an outcome of the current approach to waste management particularly liquid waste management. Three types of waste water namely yellow water flux, grey water and yellow black flux are being generated and flowing water is being used as a vehicle to dispose these. The idea of a water based disposal system e.g. flush toilet embedded in Victorian engineering has led to a technological lock-in with the result that the notion of a natural hydrological cycle has undergone a fundamental transformation.

All the same, the bulk of the load in the river is biological though there are some factories releasing effluents. In the last 20 years some of them have been closed or relocated and the river now stands a chance of being salvaged.

The public art outreach project was organized by the Max Mueller Bhavan in association with the Government of Delhi and the Goethe-Institut (Hamburg, Germany) as a part of the “Year of Germany in India” programme opened on 5^th of November, 2011. The art exhibition which continued till the 19^th of November co-curated by artist Ravi Agarwal who is also a practicing environmentalist (Director, Toxics Link) along with German artist, Till Krauser attempted to create a pulsating synergy between the Yamuna and Elbe rivers.

On the contentious policy relating to privatization of lakes, the Justice N K Patil Committee appointed by the Karnataka High Court has recommended that private sector participation solely based on commercial interest is not desirable.

In a significant development, the Committee appointed under the Chairmanship of Justice Mr. N. K. Patil, Judge of the Karnataka High Court and Chairman High Court Legal Services Committee, in response to the Public Interest Litigation by Environment Support Group challenging the privatisation of management and rehabilitation of lakes in Bangalore (WP 817/2008), has strongly recommended that ““private sector participation solely based on consequential commercial interest” is not a desirable model” (Emphasis in original).

Adequate potable water supply to the community has become an uphill task to the administration both in rural and urban areas. This is because of dwindling groundwater sources, over-extraction, pollution of surface water bodies, negligence of fresh water bodies, poor water management, etc.
