The Waterless Toilet

Most people don’t realize it, but it is not washing dishes or taking a shower that uses the most water during the day. It is truly the act of flushing a toilet. Older, less efficient toilets function by passing over three gallons of water by the plumbing system with each flush. As water resources become more scarce, ways to cut down on some of the water that is literally being “flushed away” are being sought.

One method little by little becoming more popular is the use of a waterless, or composting, toilet. These toilets are scarce in cities and suburbs because of the difficulty in securing appropriate building permits, but they are more shared in rural areas. Composting toilets transform human waste into compost, which can be utilized as fertilizer once it has been treated.

Waterless composting toilets (also known as biological toilets) are waterless systems which rely on the principles of composting by mirco-organisms to decompose human waste, paper and other materials.

In this kind of system, chambers or bins are installed below floor level. additional organic matter such as wood shaving, paper or lawn clippings, are additional to create an ideal composting ecosystem. Micro-organisms decompose the collected material, with about three-quarters being converted to carbon dioxide and water vapor. Air drawn by the pile removes these gases and assists the micro-organisms with the decomposition.

Waterless composting toilets do not treat waste water from showers, sinks and washing machines, an additional system is required for their treatment. A waterless toilet can range in price from as low as $400 to nearly $3,000, depending on the kind and features. Many models look like regular toilets and are obtainable in a wide range of colors.

Until the use of waterless toilets becomes more shared place, removing and replacing an older toilet with a more efficient one can save the average homeowner 4,000 gallons of water per year. If every older, inefficient toilet was replaced with a WaterSense-labeled toilet, nearly 640 billion gallons of water could be saved each year.

What is a WaterSense toilet? It is a toilet given a label by the Environmental Protection Agency (EPA) certifying that it uses 20 percent less water per flush than current federal standards. Typically, a WaterSense toilet uses 50 to 60 percent less water per flush than older models.

The water efficiency of a toilet depends on its age and kind. Most toilets installed prior to 1992 are considered inefficient by today’s standards, and typically use more than three gallons of water per flush. This method that a leaky, regularly running or simply inefficient toilet is the largest water-waster in a home, since toilets are by far the main source of water use in a home. In fact, flushing toilets accounts for as much as 40 percent of residential indoor water consumption.
