How many times did you go to the bathroom today? Did you ever wonder how much water is used when you flush? The answer is about 1.6 gallons. Some older models use as much as 5 gallons per flush. Around a third to a half of domestic water is used for toilets! Some people say that we shouldn’t flush every time we use the toilet, but I somehow can’t see myself doing that.
EPA calculates that more than 4.8 billion gallons of water is flushed in the US daily. The American Water Work estimates that “if water saving features were installed in every U.S. household, water use would decrease by 30 percent. That would reduce daily water used by about 5.4 billion gallons, resulting in $113 million dollar–volume savings a day.”
WaterSaver Technologies has a system that captures ‘grey’ or used water from your sink, filters and disinfects it and transfers it to the toilet tank ready for flushing.
A 5 1/2 gallon reservoir placed underneath the sink inside the vanity collects the water from the sink when you use it. A water hose connecting the reservoir fills the toilet tank control unit using gravity and a small electric pump. Inside the toilet tank a unit keeps fresh water from filling the tank so the reservoir water can be used instead. This can be adapted to most existing two-piece existing toilets that use a gravity pilot fill valve. I might try this next time I need to do any major plumbing work in my house.
