1.0 Introduction:- Rain water collection has begun since decade’s even centuries ago. Researched done by Archaeologists has proven that the rainwater harvesting systems have been used 4000 years ago in the Negev desert. The Romans during their ancient civilization also have their personal cistern in their villas. Paved courtyards were used to collect rainwater for their homes in order to lessen the usage of water by the city’s aquaducts. Today, in mainly every part of the world have started rainwater harvesting. The system is extensively installed for domestic, commercial and industrial use. By the year 2050, the worldwide availability of freshwater will have decreased by a third as a result of global warming, population growth and wasteful habits. The natural underground aquifers will be at all-time low levels. Scarcity of fresh water will become the limiting factor for healthy, livable communities. Using water conservation techniques, like rainwater harvesting systems, helps reduce the negative impacts on our water supply, keeping our cities vibrant and healthy People all over will just turn on a tap at home without realizing the consequences involved by doing so. The water provided to us through this taps has gone through many processes in order for us use to consume and use, however we just take for granted by just leaving it on. The water is just dispensed and in just a split second it disappears back into the drain. The water then have to go through a long journey, before it can be cleaned and treated again with chemicals before reappearing at the tap for our usage. The cycle is not only wasteful and illogical but polluting as well. There fore, treated water is a very costly resource to be used. Rainwater instead is free and makes sound ecological sense. 2.0 Uses of Rain Water:- Figure: Typical Household Water Usage Pie Chart Source: www.southface.org/home/sfpubs Rain water can be used for many areas, flushing of toilets and watering the garden are some of the examples. Research shows that up to almost 45 litres of water per day have been used by a person for the purpose of toilet flushing. This contaminates almost 66,000 litres of our drinking water a year in the average household. Toilet flushing is the main use of water in a house, followed by bathing and washing which uses 37 litres per person per day. Besides that, rain water is perfect for washing machines; 20 litres a day are used for washing clothes. The advantage is that the soft rainwater allows the use of natural soaps and biological washing powders, which are much gentler on clothes than standard detergents. Not only this, there is less chance of skin irritation caused by detergents, and there is no environmental damage when discharged into the waste water system.
