Low-flush toilet : ウィキペディア英語版 | Low-flush toilet
A low-flush toilet (or low-flow toilet or high-efficiency toilet), is a flush toilet that uses significantly less water than a full-flush toilet. Low-flush toilets use or less per flush as opposed to as was the norm in the 1980s and prior. They came into use in the United States in the 1990s, in response to water conservation concerns. Low-flush toilets include single-flush models and dual-flush toilets, which typically use 1.6 USgpf for the full flush and 1.1 US for a reduced flush. == Water savings == The US Environmental Protection Agency's ''WaterSense'' program provides certification that toilets meet the goal of using less than 1.6 US gallons per flush. Units that meet or exceed this standard can carry the WaterSense sticker. The EPA estimates that the average US home will save US$90 per year, and $2,000 over the lifetime of the toilets.〔(【引用サイトリンク】url=http://epa.gov/watersense/products/toilets.html )〕 Dry toilets can lead to even more water savings in private homes as they use no water for flushing.
