Abstract

Water covers 70.9% of the Earth's surface, and is vital for all known forms of life. As population of the world is increasing, water and power demand is going up. To meet that requirements, we need to find new source of power. Wastage of water is increasing nowadays. We are not using the drain water. It goes to sewage plant. It's time to think, what we can do with drain water. How can we use it? One of the ways is to reuse waste energy. Now a days people are using waste water energy for heating cold water, geothermal energy, wind, solar and bio diesel etc... In this project our target is using drain water to generate power. Today drain water is going into sewage without usage of it, there is huge amount of drain water is wasted every day in residential and commercial buildings. There are many ways this drain water can be utilized instead of wasting. The potential application of drain water is purification and reuse, heat recovery and power generation. There are already existing technologies on water purification and heat recovery but not much research in generating power. Water purification and reuse plays an important role in countries where there is scarcity of water. In this research project we consider all the options on utilizing drain water and considering pros and cons, we turn our attention on generating power using water from high raise buildings in metro cities. For our project we consider metro Toronto as an example where we can implement our new design.
