Abstract: Water and wastewater treatment processes requires huge amount of energy in around 30to 80 % of industrial operation cost. As per this background the water companies needs to identify cost effective and sustainable ways of producing energy. The generated energy should reduce its dependence on fossil fuel and ensure security of power supply. It also helps to reducing the energy cost. Micro hydro power can be available at the doorstep of effluent treatment plant, which has been identified as the solution to a sustainable energy option for the water industry. Nevertheless, there is no option available in literature of hydropower application to water treatment plants. This research gives an overview of hydropower application options available to the water industry consist of water / sewage / Effluent treatment plant. Economics plays an important role in industrial world. The power plants are design on the basis of most economical condition not on the most efficient condition by considering profit and advantage. Effectiveness of the plant is measured financially. The main goal of design and operation of the plant is to bring the cost required for energy production keep minimum as possible. Among many factors, the efficiency of the plant is one of the factors that determine the energy cost. This project measures the feasibility of implementing hydroelectric turbine systems in wastewater treatment facilities in Maharashtra, India. Thus a treatment plant named, Ichalkaranji Textile C.E.T.P. Ltd., Ichalkaranji, District- Kolhapur, Maharashtra, India was selected for a case study analysis. Based on flow and head data, 26 kW of power could be produced, generating 3.8% of the facility’s electricity needs. Payback periods were calculated to determine hydropower feasibility for other common effluent treatment plants, and 70 % were potentially feasible based on flow but depending on head.
