Wastewater

This report by the United Nations Development Programme (UNDP) presents strategies for inclusive rural development embodying the principles of environmental sustainability. It recommends measures needed to achieve green, including measuring and tracking, the use incentives and the building of capacities. It also contains a number of case studies showing how green results can be achieved.

Kerala is a rain blessed state in the country. It has highest  number of wells, when compared with other states. However due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity during summer months in most districts of the state. Further over extraction and dependence of groundwater for domestic use from the dug wells especially in rural pockets has resulted in several groundwater problems. In this backdrop the paper in  The Ecosan- An International Quarterly Journal of Environmental Science, sheds light on groundwater quality issues in two panchayats of Kerala.

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

• assess the land use changes between 1989/1990 and 2009/2010
• analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.

This handbook by Central Water Commission aims to provide necessary guidance to the field engineers in the state and central for design, appraisal, construction and monitoring of the flood management works covering all the relevant BIS codes, design manuals, guidelines, technical specifications for construction materials and practices etc. to meet new challenges in the flood management in India.

This guideline is prepared by the Centre of Excellence in the area of Decentralized Wastewater Management, in the Department of Civil Engineering at Indian Institute of Technology, Madras, which comes under Ministry of Urban Development

Any form of liquid waste discharged by domestic residents, industries, agriculture and commercial establishments into water is called a wastewater. This water contains different quantities of contaminants which pollutes water and makes it unfit for any productive or domestic use. Set against the backdrop of dire need for effective and efficient management of wastewater, this paper is a case study of Tiruchirapalli city in Tamil Nadu. The analysis provided in the paper is an outcome of the field work carried out in the city, which emphasises for developing a strategy for the management of wastewater.
