Ranjan}, title = {Contribution of Water and Wastewater Infrastructures to Urban Energy Metabolism and Greenhouse Gas Emissions in Cities in India}, abstract = { This is a first analysis of end-use energy intensity (EUEI) and greenhouse gas (GHG) emissions in water and wastewater (W/WW) sectors in India, and it examines their contribution to community-wide energy use and GHG emissions in cities in India. EUEI and related GHG emissions for W/WW infrastructures in Indian cities were analyzed and compared with data for cities in the United States. Data gathered by ICLEI-South Asia, Government of India, and the University of Colorado Denver were used to conduct this analysis. W/WW infrastructures were found to contribute 3{\textendash}16\% of community-wide electricity use and GHG emissions for 16 cities in India; for another 23 cities, the proportion was less than 3\%. EUEI for drinking water supply and wastewater treatment averaged and , respectively. EUEI for drinking water provision was more than double that for wastewater treatment, the reverse of typical cities in Colorado, likely a result of poorer source water quality in India. In general, although the sample size of Indian W/WW plants is small, EUEI in India appears to be much smaller than in the United States for both water and wastewater sectors based on this first review of quantitative data. }, year = {2013}, journal = {Environmental Engineering}, language = {eng}, }
