Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used for drinking water as well if the storage is a tank that can be accessed and cleaned when needed. advantages • Makes use of a natural resource and reduces flooding‚ storm water runoff‚ erosion

Rain Water Harvesting RAIN WATER HARVESTING AND ARTIFICIAL RECHARGE TO GROUND WATER WHAT IS RAIN WATER HARVESTING : The principle of collecting and using precipitation from a catchments surface. An old technology is gaining popularity in a new way. Rain water harvesting is enjoying a renaissance of sorts in the world‚ but it traces its history to biblical times. Extensive rain water harvesting apparatus existed 4000 years ago in the Palestine and Greece. In ancient Rome‚ residences

RAIN WATER HARVESTING Introduction: Till about thirty years back‚ the areas around our homes and offices used to be unpaved and the rain falling on these areas would percolate into the soil and remain there for being drawn through shallow open wells. With the proliferation of flat complexes‚ not only have these areas been paved and percolation of rainwater into the soil almost totally stopped‚ the quantity of water drawn from the soil below has increased manyfold. Consequently open wells and not

RAIN WATER HARVESTING INTRODUCTION 1. Urban centres in India are facing an ironical situation today. On one hand there is the acute water scarcity due to rise in consumption‚ over dependence and over-exploitation of ground water resources. Added to this‚ there is a lack of a coherent and credible water management policy. On the other hand‚ the streets are often flooded during the monsoons‚ giving rise to a situation of ‘water‚ water everywhere‚ and not a drop to drink.’ 2. This shortage

EXAMPLER ZOOLOGY STATEMENT I am applying to study Zoology because of my enthusiasm for the environment and my fascination for living organisms. I am particularly interested in physiology and animal behaviour‚ as well as ecology and biodiversity which I have studied at A level‚ and would welcome the opportunity of acquiring further knowledge on biological aspects with a focus on animals. I am currently hoping for a work experience placement at the Cotswold Wildlife Park or with the Oxford Preservation

Energy Harvesting and Nanotechnology | April 28 2011 | Energy harvesting generators are attractive as unlimited replacements for batteries in electronic devices and have been the focus of new researches for past years. This paper reviews the principles behind this technology and their integration to harvest energy. Also proposes a greener alternative for the production of quantum dots before the integration to new technologies. | Nanowires and Quantum Dots | Energy Harvesting with Nanowires

Chapter 1 Review Questions 1).Why is life difficult to define? Life is difficult to define due to the fixed properties varying from earliest living forms than those from today. This represents extensive and ongoing change refered to as Evolution. So we must base our definition on common history of life on earth. 2). What are the basic chemical differences that distinguish living and nonliving systems? The basic chemical differences from distinguished living and non living systems are:

MICROSCOPY Objective: 1. To learn how to use both a dissecting and a compound microscope effectively and efficiently (lighting‚ focus‚ magnification‚ resolution)‚ and to practice manipulating small organisms Principals: 1. The smallest object viewable under a compound light microscope is limited by resolution or resolving power (ability to distinguish between two nearby points) and not magnification. 2. Mircoscope resolution is limited by the wavelength of the source of illumination (visible

implemented to provide clean‚ reliable water in close proximity to its end users. Rainwater harvesting is one of these options available for consumers. It has the potential to provide water for a variety of purposes. Rainwater harvesting is one of the most basic forms of water collection and has been used for millennia around the world as a means of collecting and storing water for future use (UN-HABITAT). Rainwater harvesting is just one of many options for water supply in areas where water is scarce
