The first step to conserving water and saving money on water and wastewater bills is making sure you have efficient plumbing fixtures.  With toilets accounting for about one-third of indoor water use, replacing older, high water use toilets with high-efficiency models is one of the best ways to save water.

Upgrading to a high-efficiency toilet can reduce your total indoor water use by roughly 16%. That's an annual water savings of 20,000 gallons per year for a family of four! Whether you're looking for ways to save money in your home or business, or are managing a multi-family property, high-efficiency toilets can help achieve significant water savings.

ULFT vs. HET?

It has been more than a decade since Federal laws mandated that the toilet flush volume for models sold in the United States could not exceed 1.6 gallons per flush. These models are called Ultra-Low Flush toilets and they are the highest flow models available on the market today. Prior to this standard, toilets flushed at 3.5 to 7 gallons per flush.

High-Efficiency toilets (HET) flushes at least 20% below the standard model. Many HET’s are dual-flush toilets, which have two separate flush volume options. By the year 2014, high-efficiency toilets will be the standard.
