International Journal of Innovative Technology and Exploring Engineering (IJITEE) ISSN: 2278-3075, Volume-9 Issue-4, February 2020 2787 Retrieval Number: D9090029420/2020©BEIESP DOI: 10.35940/ijitee.D9090.029420 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Abstract: Urban cities rely on surface water resources such as lakes, rivers for their survival, anthropogenic activities, rapid urbanization and industrialization had put thrust on such water bodies in major cities across India. Bountiful research works conducted also proves that such resources are rapidly depleting, and it also conveys that very few reasons contribute to major deterioration of lakes. Two major parameters that contribute to this deterioration include discharge of sewage into the water bodies and unplanned encroachments along the banks. This study aimed as a sustainable water resource management technique to rehabilitate a highly deteriorated tank in Kovilambakkam village, Peri- urban in Chennai city, India. The tank which is one of the primary sources of water for the area is affected highly due to urbanization and the natural ecosystem is disturbed. A best possible solution for rehabilitation is suggested using Socio-Economic method utilizing qualitative analysis like a PRA tools (Transect Walk, Focus group Discussion, Key Informant Interview, Resource map, Semi-Structured Interview), measures to improve and safe guard the lake were taken. To analyze the performance of the work water quality analysis was done to verify physical, chemical and biological parameters, both before and after rehabilitation is done, it is found that the performance with reference to biological parameters such as MPN index. Promising results were obtained in this study restoring the lake to its original condition which started serving the indigenous people proving the effectiveness of the suggested method.

INTRODUCTION Based on the renewable water resources available in our country (India), we are ranked 7 th in the world and 3 rd among all the other Asian countries. More over based on ground water recharge it stands in 5 th position among the world and 2 nd among Asian countries (Sakthivadivel et al., 2016). It is stated that many rural areas in the country entirely depend upon the surface water resources for many purposes as agriculture, households and more. Ground water availability increases the chances in agriculture.(Suba, 2014). In the last few decades raising human population have made the supply of natural water limited owing to rapid depletion of ground water quality and quantity thus creating water stress. Demand for pure water resource increases day by day in urban cities of Revised Manuscript Received on February 06, 2020. * Correspondence Author R.

India which is not supported by the disastrous rainfall pattern India faces during the last two decades (Reddy, 2015; Ramachandraiah and Sheela Prasad, 2004). Urban infrastructure is unable to bare this burden and affecting the urban dwellers with limited water resources. It is a great challenge for administrators of any state to manage its water resources to supply water to its rapidly developing urban cities (Anuradha et al., 2009). Indian kings who ruled ancient India had constructed numerous tradition surface storage systems named as - ponds / lakes / talab / cheruvu / aari (regional names of tanks) (Nagarajan, 2013; Palanisami and Ruth Meinzen, 2001). For the past 2000 years they helped in sustaining the agriculture even in many dry areas of the country. This includes dry zones of India as well as South East Asia. The number of tanks availble in India are about 2.1 million. And nearly 120,000 are existed in southern peninsula of the country, covering many important states as Andhra Pradesh, Karnataka, Tamil Nadu and union territory of Pondicherry which takes into account 60% of tank based irrigation (Vaidyanathan, 2001). Tanks that are well connected supported the effective usage of water in arid and semi-arid regions and certain management practices were implemented at improving effective usage of water during drought situations (Tennakoon, 1986;Frederick, 2008). But recently there is a decline in the usage of traditional tanks owing to alternation source availability such as reservoir, canal, lift irrigation(Morun, 2007). Also there occurred a paradigm shift towards usage of modern irrigation systems, construction of artificial and larger reservoirs, dams, river valley projects have considerable impact on usage of tanks and they become a low key issue (Balasubramanian and Bromley, 2002). 1.1 Tanks and their impact on irrigation A tank by definition is an earthen bund that may be constructed across a shallow valley or between two land mass to sustain the rainfall runoff from its catchment area, they may be isolated or cascading type in which the primary surplus fills the next tank and it goes on until the last tank gets filled in (Anuradha and Ambujam, 2012). Always in Tamil Nadu are the main sources of irrigation covering huge irrigation area from time immemorial, Figure 1. depicts the area covered by tanks and other water bodies.(Asian Development Bank,2006) and table 1 covers the information about amount of tanks present in various districts of Tamil Nadu Tank Rehabilitation in Chennai Peri-Urban Area Saravanan S.
