Dual flush toilets
Humanity once thought that water was an infinite resource. The seas, rivers, and lakes flowing perpetually down their designated paths. An endless stream of life giving nutrients just there for the taking. Back then the people who thought about it were right, but nowadays you'd be called a raving lunatic for saying that. Pollution has affected our water systems greatly and poses a great threat to as all. So that's why humanity has turned to technology to aid them in their fight to preserve mother nature and the source of life: water.
Specialties of the Dual Flush Toilet
An Australian inventor by the name of Bruce Thompson invented the dual flush toilet in 1980 while working for Caroma. A dual flush toilet is a variation of the traditional flush toilet that mostly relies on gravity. It has two buttons for solid and liquid waste disposal. A redesign in of the product in 1993 cut water usage in half when used properly. It has been further proven to save up to 67% of water in most homes. The idea of two buttons or flushes came from the thought of handling different levels of water. Standard toilets would normally use 5 gallons (19 liters) for every flush while approximately only 3 liters of fresh water is used for liquid waste and 6 liters for solid waste.
Dual flush toilets handle both solid and liquid wastes which make them different from the typical American style toilets and provide the user with options for flushing. This is a convenient method - a half flush for liquid waste and a full flush for solid waste. The way water is used to remove waste from the bowl has a lot to do with the amount of water needed to get the job done. Standard toilets use siphoning, a method that utilizes a siphoning tube to remove waste. When the toilet bowl is flushed a high volume of water fills the siphon tube and pulls the waste and water down the drain. The siphoning action stops once air has entered the tube. Dual flush toilets employ a larger trap way (the hole at the bottom of the bowl) and a wash-down flushing design which push waste down the drain. Because there's no siphoning action involved, the system needs less water per flush, and the larger diameter trap way makes it easy for waste to exit the bowl.
Water Saving Machine
Due to its ability to cut down fresh water usage up to 67%, the Australian government promoted the dual flush toilet under its Target 155 campaign. The Australian government is encouraging the replacement of their existing single flush toilets for the more water efficient ones through toilet rebates. However this fresh water saving equipment doesn't come at a cheap price right now. Certain retrofitting has brought down the prices significantly to only US$30, which is still a big amount.
A 1994 National Energy Policy act requires all toilets sold in the United States to use no more than six liters of fresh water per flush. This legislation led to the development of HET's (high efficiency toilets) which use gravity flush, pressure-assist, and dual flush to remove waste while using as little water as possible. This innovation would eventually lead to reducing the demand for local water treatment facilities. According to USA Today an average person will flush five to eight times on a regular day, that is five to six greedy gallons per flush. The Environmental Protection Agency also claims that the United States alone can save up to 2 billion gallons of water each day if they were to replace all of their single flush toilets..
This technology has not yet received its much needed share of attention. Some parts of the world, especially poor and underdeveloped countries, aren't even aware of its existence. Today, the dual flush toilet is widely used in Australia, the United States of America, Europe, and Asia. The idea of a dual flush toilet system can be tedious and financially heavy, but it is worth it so we can take the next step towards a better tomorrow. Every form of effort counts because it's all being done for one very important purpose- to sustain our way of life. Talking about toilets is never a nice way of striking a conversation, but if we make others aware about the benefits of a dual flush toilet, then we're already doing our planet a big favor by letting others know that it too, needs to survive.
