Risparmio idrico, un flusso alla volta: il WC ad alta efficienza


Translating…

With today’s technology and manufacturing standards, there are several different toilet fixtures available to homeowners. Increasingly gaining in popularity, are high efficiency toilet models. To the average homeowner, the only appearing difference between a high efficiency model and its lower priced counterpart may just be cost. However, there are several differences that every homeowner should be aware of in making the proper choice.

“The Porcelain Throne,” prior to manufacture in the mid 90’s consumed as much as seven gallons per single flush. Older traditional toilets would have tanks that would consume surprising amounts of water and take quite some time to fill. In 1994, in the United States, Congress enacted the National Energy Policy Act which required that toilets sold in the US could no longer use more than 1.6 gallons of water per single flush. While older models manufactured prior to 1994 still exist and are in use within homes, most have opted to switch to newer models in light of conservancy. According to the Environmental Protection Agency, the elimination of all of these older model toilets from homes would result in a savings of two billion gallons of water, daily.

Originally when the 1.6 gallons per flush (GPF) toilets were manufactured, they were inefficient at flushing waste placing a stigma around higher efficiency models that were created. A High Efficiency Toilet by definition is a model which only utilizes 1.28 GPF or less. Despite the misconception that the use of less water will inhibit the disposal of waste, today’s high efficiency models do just that – flush wastes utilizing less water.

Generally within these high efficiency toilets, there are three options available, single flush, dual flush and pressure-assisted models. A single flush model is exactly what it states and generally uses gravity to assist in disposing of waste with less than the mandated 1.28 GPF. The dual flush model uses “smart assisted” technology in having its user have the preference of less than a gallon flushes for liquid waste versus using a bit more water volume for other wastes.

While high efficiency models are more expensive then their counterparts, those looking for savings over time will benefit greatly from opting to install one in their home. Households can save more than 4,000 gallons a year with a high efficiency toilet. Homeowners may also qualify for money saving rebates dependent on their locale. In addition to water conservancy, a family of four can save approximately $ 100 per year in water bill reductions and up to $ 2,000 over the lifetime of the toilet.
