High-efficiency toilets (HETs) have been defined by the plumbing industry and the Environmental Protection Agency (EPA) as those that use an average of 20% less water per flush than the industry standard of 1.6 gallons.
For a family of four, that can mean a savings of almost 9,000 gallons of water each year. That’s not only green, but it also makes sense, especially in an age where public water prices are on the rise and aquifers are being depleted.
The Partnership for Advancing Technology in Housing (PATH) highlights four styles of HETs on its list:
* The gravity-fed single flush toilet operates like a traditional toilet but can use as little as 1.1 gallons per flush.
* For households who want more than one option when flushing, the dual-flush toilet allows you to choose between one mega flush, which uses up to 1.6 gallons of water, or the more modest light flush, which rinses with only .8 gallon of water. These toilets average out to use about 1.2 gallons per flush over the course of a year.
