Rapid evaluation of water supply project feasibility in Kolkata, India

Abstract

Mega cities in developing countries are mostly dependent on external funding for improving the civic infrastructures like water supply. International and sometimes national agencies stipulate financial justifications for infrastructure funding. Expansion of drinking water network with external funding therefore requires explicit economic estimates. A methodology suitable for local condition has been developed in this study. Relevant field data were collected for estimating the cost of supply. The artificial neural network technique has been used for cost estimate. The willingness to pay survey has been used for estimating the benefits. Cost and benefit have been compared with consideration of time value of money. The risk and uncertainty have been investigated by Monte Carlo's simulation and sensitivity analysis. The results in this case indicated that consumers were willing to pay for supply of drinking water. It has been also found that supply up to 20 km from the treatment plant is economical after which new plants should be considered. The study would help to plan for economically optimal improvement of water supply. It could be also used for estimating the water tariff structure for the city

Water supply project feasibilities in fringe areas of Kolkata, India

“…A previous CBA study (Dutta Roy et al, 2010) conducted for the city of Kolkata has been extended for the peri-urban areas in this article. The block diagram presented in Fig.…”

“…The present authors investigated about the water supply network feasibilities in Kolkata in an earlier study (Dutta Roy et al, 2010). In the study, artificial neural network (ANN) have been trained for estimation of booster pumping station costs based on size, land rent and distance from the treatment plant.…”

“…The benefit of the project is first estimated based on a willingness to pay (WTP) survey which is fairly common even in Kolkata (World Bank, 2001;Roy et al, 2003;Guha, 2007;Majumdar and Gupta, 2009;Dutta Roy et al, 2010). The consumer's spending capacity and experience and awareness about a product have an impact on the WTP.…”
