All the waste water of the building that are to be disposed in public sewage through excrete pipes is first stored in a giant storage tank situated at a suitable head in the building. The water that is stored in whole day is discharged through pipe with steady rate by using gear. Water of steady rate of discharge falling from a great head when strike the blades of turbine produce energy.

Introduction Water, food and energy securities are emerging as increasingly important and vital issues for India and the world. Most of the river basins in India and elsewhere are closing or closed and experiencing moderate to severe water shortages, brought on by the simultaneous effects of agricultural growth, industrialization and urbanization. Current and future fresh water demand could be met by enhancing water use efficiency and demand management. Thus, wastewater/low quality water is emerging as potential source for demand management after essential treatment. In urban areas the consumption of water is more but the supply is limited. As the population is increasing day by day, hence the per capita consumption is also increasing. So as to counter this upcoming future problem, we have to think beyond the box. Management of waste used water for the sack of production of electricity can be a good alternative. Combining renewable energy to form standalone hybrid systems is considered as one of the most promising ways to handle the electrical requirements of tall buildings. Beside the residential applications, the idea of studying the self-sustainability of power in industrial & service facilities looks very appealing due to their relatively high energy demand, such as wastewater treatment plants (WWTPs). This is because water pollution by nature is an energy intensive process. Also, the operating costs of waste-water treatment facilities in the recent years have increased substantially due to the in- creases in the unit cost of energy. II. Management of waste water In long storeyed buildings in urban areas where the gallons of waste water are discharged through pipes can provide an efficient source of water to produce electricity. All the waste water of the building that are to be disposed in public sewage through excrete pipes is first stored in a giant storage tank situated at a suitable head in the building. The water that is stored in whole day is discharged through pipe with steady rate by using gear. Water of steady rate of discharge falling from a great head when strike the blades of turbine will produce energy. But as the space is restricted here, so the usage of normal giant turbine cannot be done. So the introduction of Micro hydro turbine can be a great idea. Micro hydro is a type of hydroelectric power that typically produces up to 100 kW of electricity using the natural flow of water. These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks. There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel.Micro hydro systems complement photovoltaic solar energy systems because in many areas, water flow, and thus available hydro power, is highest in the winter when solar energy is at a minimum. Micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. The installation is often just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing.The turbine turns a generator, which is then connected to electrical loads; this might be directly connected to the power system of a single building in very small installations, or may be connected to a community distribution system for several homes or buildings.
