What Are The Advantages Of A Rain Water Recycling System?
Rain water recycling has more applications then grey water recycling as it can be used not only in the gardens but also for flushing toilets, washing clothes and can also be used for drinking after it has been treated. It is possible to reduce your mains water usage by up to 40% with the use of a rain water recycling system connected to a well plumbed storage tank. It has a very low operating cost (power to run the pump) and because it is the water caught from your roof it is free and can provide water for your gardens and lawns without restrictions all year round. Depending on the size and intended use these systems can usually be installed from $4,500 for a smaller system to around $15,000 for a large system.
What Options Are Available With Rain Water Storage?
Rain water is collected from the roof and stored in tanks. There are a few different options with storage depending on required usage and space available. Standard tanks are for installations where space isn’t an issue, but when it is Slimline tanks are available where the intended installation area is narrow like the side of a house. Underground storage tanks are also available so that storage capacity can still be maintained but not take up to much room this option has the added cost of excavation and backfill to install the tanks.
Also depending on the application, tanks can be made from a few different materials with the most common types being poly or colourbond. Plastic tanks can be used in above and below ground installations and also come in a variety of sizes, shapes and colours to suit almost every situation. Colourbond tanks are usually for above ground installations and also come in a variety of sizes and shapes but have a larger range of colours available and can be made to the match the colour of the roofing, spouts or down pipes.
How Does The Rain Water System Work?
The system is generally comprised of a storage tank or tanks, pump and controller. The controller is the brains of the system and controls whether to use rain water or mains water. It will always use rain water first. If however in the event there is no rain water available or during a power outage the controller will switch over to mains water so that water is always available.
The mains water is protected with a backflow prevention device to prevent cross contamination as well. Depending on the application required will also depend on the pump required but there are two main different types that come in various sizes. Submersible pumps are usually used when the storage tanks are below ground and pressure pumps are used for when the tanks are installed above ground. The size of pump required is calculated by pressure and volume of water required to ensure the system works to full capacity. If the water is intended for drinking water there are also treatment units available that make the water safe to drink.
