Introduction
Introduction Mumbai, is one of its 10 mega cities of the world and business capital of India. Mumbai proper occupies a low-lying area that once consisted of seven islands called Colaba, Mazagaon, Old Woman's Island, Wadala, Mahim, Parel, and Matunga-Sion separated from each other only during high tide. The population has risen from merely 3 millions in 1951 to 12 millions as on 2002 out of which 50 % live in slums It also supports “daily commuting” population of 20 lakhs It covers an area of 437 sq.km. With average density of 36600 soul/ sq.km. Water Supply-From Past To Present Prior to 1870, the Mumbaikar used to drink water from the existing well, lakes and tanks. But during middle of nineteenth century, because of the epidemic, decision was taken to build a dam to supply good quality of potable water, and then onwards Bombay water works started functioning The history of Mumbai’s water supply dates back to the 22nd June 1845. On this day, the then Government in response to the agitation of the native appointed 2 men Commission to report about the quality and quantity of water available in Mumbai. The Commission reported back within 24 hours that the water supply of Mumbai needed immediate attention. This was the beginning of efforts to search sources of water to satisfy the City’s demand. It is the first city in India to receive piped water supply in the year 1860. Today it supplies 2950 MLD every day, is one of the largest water supply in Asia. -

Box 118 Webpage: http://www.byggvetenskaper.lth.se SE-221 00 Lund Sweden 2 Informal Housing Markets and Redevelopment - A Case Study of Dharavi Preface During our academic years at the Faculty of Engineering, Lund University, we have obtained fundamental knowledge regarding property related economics, law and technology. Throughout the education, we subsequently became interested in the subject of development of land and cities. As both of us are internationally oriented, we saw the possibility to deepen our knowledge by focusing on an international matter in our master thesis. We are grateful to SIDA for providing the economic grant that made this research and the journey to India possible. We would also like to thank our supervisor Stefan Olander, Associate Professor at the Division of Construction Management, Lund University, for giving valuable support and advice throughout the course of research. The time spent in Dharavi, Mumbai during our case study has been very intense and at times difficult, but foremost interesting and rewarding. We have obtained many significant experiences, which we would not have been able to gain from a desk in Sweden. For this we would like to thank field experts for sharing their thoughts and the inhabitants of Dharavi for their time and hospitality upon inviting us into their homes and sharing their life stories. -
The 7 Islands of Bombay/Mumbai
The 7 Islands of Bombay/Mumbai Bombay, now Mumbai, more correctly Greater Mumbai, started out as seven small islands with villages of Kolis, the local indigenous people of this part of Western India. Their main means of living was from fishing and their goddess was Mumba Devi from which modern Bombay was finally renamed Mumbai. Greater Mumbai includes the northern large island of Salsette or Vasai which remained a Portuguese territory for a longer time whilst the seven islands became English regions after 1661. Some of the most ambitious reclamation ever undertaken in Asia involved not just joining these islands, but reclaming huge parts of sea separating the islands as well as vast empty tracts of water in between. These were seven islands when the Portuguese ceded these to the British as 'dowry' for the marraige of the English King Charles II to Catharine of Braganza of Portugal, in 1661. For a very interesting history of Mumbai see this site: http://theory.tifr.res.in/bombay/history/ that traces the history of this region from the Stone Age, through the Magadha Empire, to the Muslims of Gujarat to the Portuguese and the British, and finally the capital of commercial India. There is some controvery on the origin of the word Mumbai-it is now claimed the word Mumbai is derived from the word for the local diety of the region, a goddess called Mumbadevi. The Portugeuse who first claimed posession of the seven islands called these Bom Baie, meaning Good Bay, and the city was called Bombay upto the early 70's, when the name was changed to Mumbai. -

Arjun Appadurai1 The nature of the municipal tap is feudal and bureaucratic. … You left the tap open before you went to sleep. When the water sputtered and splattered at three, four or five a.m. and sometimes not at all, was when your day began. Kiran Nagarkar2 In a dusty office of the municipal buildings in B ward in downtown Mumbai is a detailed map of the Paris water supply system, placed under a sheet of thick glass on the desk of the chief engineer. This “hydraulic dec- oration” acknowledges an attachment to a utopian vision of the perfect city: a striving toward a perfect synthesis of engineering science and urban modernity. The intricate arrangement of blue lines—varying in thickness Chapter 4 and shading to depict the hierarchical structure of the city’s water mains— is counterposed with the familiar bridges, boulevards, and radial subdivi- sions of the Parisian arrondissements. This striking cartographic representation of Paris is suggestive of a tension between the idea of the modern city as a visible manifestation of conscious design and the complex array of unseen networks extending beneath the city streets. -
Urban Water Conflict in Mumbai
Institutional Design and the Geography of Rural- Urban Water Conflict in Mumbai Punjabi, Bharat Post-Doctoral Fellow Institute of Municipal Finance and Governance (IMFG) Munk School of Global Affairs University of Toronto (Not to be cited without permission of the author) 1 Abstract: Water security in metropolitan cities is increasingly important in the developing world. In Mumbai, for example, rapid urban growth has dramatically increased the demand for water, which has resulted in serious consequences for the water entitlements of rural communities located near the sources of water. This presentation focuses on the regional dimensions of water delivery and looks at the role of institutions and the impact of local laws, agencies, and governance on how water is shared between rural and urban areas. Key words: Urban; rural water access; metropolitan urban governance; commons; Mumbai; India 2 Introduction In the case study literature on the commons, there are few studies that examine the institutional implications of water demand for a growing metropolitan region on its rural hinterland.1 Urban expansion and growth often leads cities to take water from distant rural watersheds that irrigate agriculture for urban use. Urban water appropriation is rapidly becoming an important policy question in developing countries. At the same time, the institutional mechanisms and regulatory frameworks that underlie access to water from rural areas are poorly understood. Through a case study on the city-region of Mumbai, India, this paper tries to develop a new understanding of an unexplored institutional dimension of inter-sectoral water politics. This paper hopes to make a contribution to the institutional and metropolitan governance literature on water in large city-regions. -

Water Supply Problem Water Is the Lifeline of All Living Beings, but Its Availability Is Totally Dependent on the Quantum of Seasonal Rains
B U D G E T E S T I M A T E S A , B & G 2010-11 Mr. Chairman, I am presenting to the Standing Committee, the estimates of receipt and income and expenditure pertaining to the Budgets ‘A’, (Fund code 11, 12, 60, 70), ‘B’ (Fund code 21, 22, 23) and ‘G’ (Fund code 40) for the financial year 2010-11 in pursuance of the provisions of Sections 125 and 126 E of M.M.C. Act 1888. I am profoundly delighted to present Budget Estimates of Brihanmumbai Mahanagarpalika as the Municipal Commissioner for the first time. When I took over as chief of the Municipal administration of the Municipal Corporation of Greater Mumbai, which is one of the foremost in not only the Nation, but across the globe, I had to face two very stiff challenges. One, the drinking water crisis faced by Mumbaikars due to scant rainfall and second the critical financial position of the M.C.G.M. Water Supply Problem Water is the lifeline of all living beings, but its availability is totally dependent on the quantum of seasonal rains. The daily average requirement of water of the city of Mumbai is 3400 million litres. However, barring 4 days in August 2009, the rains had turned their back on the entire Maharashtra. As a result, this year, the reservoirs like Tansa, Vaitarna, Bhatsa, Upper Vaitarna, Vihar etc. did not reach the desired levels which normally overflow in the mid of August every year. An attempt was made to induce artificial rain in the catchment area from August 23 to October 22, 2009. -
