Rainwater tanks have become increasingly common in many places of the world. Due to the decline in water supply in many areas of the world, there is a sustained campaign for reduced usage of domestic and commercial water, and adoption of alternative water supply and storage systems. Rainwater harvesting systems has been identified as a reliable means of a water supply. The method is designed to capture rainwater into a designated tank before supplying it to buildings after it has gone through some pre-filtration processes.
Rainwater collected from rooftops can contain particles and debris like leaves or blossoms, eroded roof materials and bacteria. This material can block pumps and the pipes that will convey the water to the building. Apart from the dangers of blockages unfiltered rainwater can also contain toxic by-products that may cause damage to laundry, the skin if used in showers or can make you sick if you are drinking it.
There have been several means used to circumvent or prevent these problems, but one of the most convenient and easy means of filtering rainwater is by installing a first flush diverter. This device is designed to prevent the initial runoff that comes from the roof before it is allowed to be collected in the tanks. The use of a first flush diverter is extremely beneficial for regions that have an extended dry season and then severe rainstorms. Countries like Australia and New Zealand have a great need for this device for their rainwater harvesting.
However, while some countries may not need rainwater harvesting first-flush diverters as much, it is still very important that a highly efficient and easy to maintain mechanical filter is used for the rainwater harvesting system that has been installed. The amount of filtration needed for rainwater is dependent on the purpose for which the water is intended. If is it for residential purposes or is it for commercial purposes; and to what extent will it be used. Systems like rain barrel systems do not need an elaborate or complex filtration system. Some people use only the rainwater harvesting first flush diverters, while others have to use a very mechanical rainwater filter systems, especially if the rainwater is used for indoor plumbing and potable purposes.
While some people do not believe that rainwater can be filtered to the extent where it can be consumed or used for cooking there are however various filter systems that can effectively clean harvested rainwater for any potable and domestic use. Rainwater harvesting systems have been of immense benefit to many people across the world. It is very cost effective and it has helped reduce domestic and commercial expenditure of individuals and corporate organizations alike by drastically reducing the water bill.
Choosing a supplier for these rainwater tank and accessories can be very difficult for people that don’t know much about the process. When there are several different suppliers to choose from, you may want to look at the warranty they offer, how their products differ from others, price and the level of service you get from them.
