Different parts of the globe have different kinds of climate. There are places with extreme climates, some places receive plenty of rainfall and some do not get much rain and are considered dry lands. With the effects of the global warming the planet earth has become a tougher place to live in. The rivers, flowing in different parts of the globe are getting dry slowly. In many cities today people do not have sufficient water for their living. Even though there are a plenty of methods implemented to convert waters from oceans to drinking, through processes like desalination and so on. We have not been able to get sufficient water for our living. Hence, the life of people mainly in the cities where the density of the population is huge has become tough with water. In Many cities today people have to buy water for their usage.


Keeping all these above problems in mind, the environmentalist have come up with a new concept of rain water harvesting. Although, this concept of rain water harvesting was introduced quite recently, it has helped people to get some amount of water at least during the rainy seasons. However, ...
... the concept has been developed in many places. By now most of us are aware about the concept of rain water harvesting and we can quote examples where it is implemented. However, rain water harvesting talks all about preserving water that comes in the form of rain. This water can be preserved and later be used during the dry seasons. Most of us are aware when it rains, a lot of water just flows in the ground. Hence, even if can’t preserve all the water the flows through the rains. At least, a ten percent of this water can be preserved. Even there is a heavy down pour for an hour or so, this could help us use that water for a day.


This water could also be used for irrigation. Today we find a lot many people doing this. They have built in huge storage tanks where the flowing water gets accumulated. We can use this water in the fields especially at times when there is no rain and water is required for the irrigational lands. Hence, numerous methods have been invented and due to the technological development just like we have storage solutions with regard to the television and internet system at home. Rain water is also based on the concept of storage solutions. There are three kinds of system based on the used. The first is the domestic system and this could be related to using rain water stored for domestic purposes at our homes. The second is the Garden system is used for watering the plants and the third is commercial systems that can be used for commercial purposes.


In all these three systems there is a process of filtration before the water is used. Based on the purpose of using this water, there are different techniques used. For example the commercial system of rain water harvesting uses these tools mentioned below. Filter, Smoothing inlet, Submersible pumps, floating suction filters, control panel and switch board, solenoid valve, float switch that measures the depth of the water, type A air gap tundish, float switch which protects the pump from running dry, expansion vessel, pressure hoses, 160mm drainage pipe used as duct, overflow trap which protects the water from over flowing, optional tank level gauge is used to measure the water level in the optional tank and the mains water supply. Even though all these names might make it look complicated the process is very simple. The commercial versions are usually larger, more sophisticated than the domesticated systems. Even the components are much larger depending on the supply and demand of the water that is required and a facility to monitor both mains and rain water can also be included.
