Rain Harvesting In Malaysia - Modern Method To Recycle Rain Water

By Joseph Devine


The entire world is facing water scarcity problem. Some areas of Malaysia also have this problem during specific time. Water is without doubt one of the limited natural resources which nature has provided to mankind. Using this limited resource wisely and repaying it back to the earth is an important problem in current times. Some of the efficient method of refilling the water levels is rain harvesting.

Rain water harvesting is now thought of as a national initiative in Malaysia. It is likely one of the important issues which can keep good balance of water in the environment. Rain water harvesting is sometimes also referred as rainwater recycling.

Within the urban residential areas the need for water is more. The water supplied at these areas is treated and such water is called portable water. This water is used for drinking as well as for doing every washing and cleaning jobs too. If rainwater recycling project is set up by the residential areas, then the rain water kept in tanks can be used for general washing requirements and the portable fresh water could be saved to great extents.

The price of potable water supplied by the municipal corporations in Malaysia could be very high as compared to the rain water harvested and kept in the tanks. Large money saving could be achieved by setting up rainwater recycling projects.

Looking at the time for which it rains in Malaysia; rain water may be good resource of fresh water for considerable time in the course of the year. As the country has a superb business of tourism, rain harvesting projects can also be undertaken by big hotels and restaurants located in the metro cities of the country.

By meaning of the term, rain harvesting means simply collecting rain water in tanks for future usage. But now people have made good research within this area and have devised equipments and methods by which rain harvesting might be done efficiently at domestic as well as industrial levels in the the USA like Malaysia.



A number of instruments and units that are normally utilized in rain harvesting are specifically pressure vessels, filters and also pumps. There are some common terms that are used while setting up the rainwater recycling projects. These terms are listed and suggested below.

The very first term is water catch surface. This defines the area from which water is caught throughout the rain harvesting or rainwater recycling. That is considered as the starting point of the project where the area is decided. Then after looking at the average rainfall within the area, it's that how a lot water may be caught during a single rain cycle.

Next term is channels which means what sort of piping or canalizing required to be done to take the water from the roofs to the storage area where rainwater recycling is to be done. If the rain water is going to be stored in closed tanks, then before sending it to the tank the water is filtered by setting up filters at some points.
