Water resources are under pressure from continuing population growth and urbanisation, rapid industrialisation, and expanding and intensifying food production, particularly in developing countries and in urban areas. Urban populations may nearly double from current 3.4 billion to 6.4 billion by 2050. Numbers of people living in slums will rise even faster, with most of the rapid expansion in urbanization taking place not in megacities (21 of the world’s 33 megacities are on the coast), but in small and medium sized cities with populations of less than 500 000.
Aim of the project is to generate electricity from waste water. It will provide electricity to the rural areas. It will enhance commercial and economical development in isolated areas. It can minimize the operational cost, economical cost, transportation cost.
• In addition to wind and solar energy, the so-called biofuels are becoming increasingly common.
• Generating energy through burning, vaporising, or fermenting biomass such as leftover plant material, vegetable waste, and manure are well-tried methods.
• A new shoot on this branch of energy production is the generation of electricity from waste water, which is capable of directly generating energy from substances such as waste water.
• At the present time, this has only been done in the lab, but the first results and applications of this new technology are very promising.
• If we use the concept of hydroelectric power plant, we can generate the electricity by using waste water instead of water which come from natural resources.
• We collect the waste water and transfer it for the process of physical analysis in lab to control its physical characteristics.
• After physical analysis it will transfer to pass through the turbine for electricity generation.
• Due to application of waste water on turbine it will rotate at particular amount of RPM and generate the electricity.
• They are testing organic materials which may act as catalysts on the process. They are also improving the design of the model to enable generating electricity on a larger scale.
• We collect the waste water which is generated by kitchen waste or domestic waste or industrial waste. In this we will done the sampling of waste water for the treatment.
• After collection of waste water physical analysis of waste water which is generated from kitchen waste, domestic waste and industrial waste is done.
• Screening will be takes place with the help of trash rack. In screening solid suspended matter which are present in waste water will be separated.

• After screening process sedimentation of waste water will be takes place. Sedimentation is the process in which small suspended particles will be settled down.
• After the process of sedimentation the waste water is transfer to pass through the turbine.

• Before the waste water passes through the turbine it will pass from surge tank. Due to surge tank the velocity of waste water will be constant. It carries constant flow of waste water.
Fig.5 Surge tank
• With the constant flow waste water will be applied on the turbine with high pressure.
• Due to application of waste water the turbine will rotate at particular rotation per minute and generate electrical energy.
