January 18, 2010 1:18 pm Water TanksThough the term rain water harvesting system makes it sound complicated, it is nothing but collecting rainwater, storing it for later use. Water being one of the most important elements of survival we should make the best use of the resources that are at our disposal. Australia is notorious for its water scarcity problems and the government is encouraging people to go for rainwater harvesting systems to help themselves and the government. Rainwater harvesting systems can be installed in just about any building including commercial buildings, schools hospitals, homes, hotels etc. As we continue to deplete earth’s resources, we need to make the effective use of rainwater that goes wasted. You can make use of the rainwater you collect for flushing the toilets, carwash, watering plants etc. This is one of the best eco-friendly approaches to life.
If you want to harvest rain water, you first need water catch surface which is nothing but the roofs of your homes or buildings. Rainwater that falls on the water catch surface should be channeled through the right path and moved to the water storage facility. Today you can get readymade water storage tanks. Polyethylene water tanks are one of the most popular forms of water storage tanks used these days throughout Australia. You can also make use of metal tanks but metal water tanks are not as durable as Polyethylene water tanks. Before the water reaches the water tank, it should be filtered so that you get clean water stored for your use. When you are installing your rainwater harvesting system, you must choose a reliable filtering system. Your filters need regular maintenance for effective collection of water. If your filters get clogged, water may not reach the water tank fully and there may be a lot of wastage on the water channels.
Water transport system is another aspect of your rainwater harvesting system. The water you have stored in your water tank should reach the outlets in your home. So you need to have a separate plumbing line. Moreover, you would also need pumps to pump the water either to an overhead tank or to the water outlets. You must choose the right pump or motor to pump the water.
Many people hesitate to install rain water harvesting system in their homes because they think that it is very expensive to install the system with all the components discussed above. If you too are thinking the same, you should remember that this is a one time investment which will pay for itself over a period of time and start bringing considerable amount of savings month after month. Your overall water bills will reduce and moreover, you will not have to face water scarcity problems even during the driest months of the year. Make sure that you choose the best water tanks so that you are not forced replace it frequently. If you install a good water tank you need not have to worry for a minimum of 15 years.
