Energy Efficient Approach for Waste Water Treatment Plant

Abstract

An ambitious programme of 100 smart cities has been announced by government of India. A speedy upgrade in infrastructure and online services that too enabled by Information Technology is expected to be witnessed by the state capitals, tourists and heritage cities. Frameworks would be developed in consultation with a wide cross section of industry members and Government stakeholders and its partners. As a step towards building a digital India, the NDA government has proposed (in the latest budget) to earmark Rs. 7,060 Crores towards building of 100 smart cities across the country. These 100 smart cities are expected to provide sustainable and healthy living spaces in order to deliver greater efficient basic infrastructure services along with highly efficient environmental and economic resource use. One vital concern is the provision and usage of water. This paper argues that an integral role will be played by the energy efficient decentralised wastewater treatment facilities in coming years in smart cities. In particular, it focuses on two main points. First, there will be huge increase in use of waste water treatment for recycling and reuse of water streams so as to meet increasing water demands. Second, decentralised approach will be strongly favoured over centralised approach of waste water infrastructure due to the need of recycling and reuse at the point of usage. A case study of Pune city sewage disposal scheme is presented in this paper. Analysis of different types of energy associated with such system is done.
