From the Village Voice:
Carter Strickland, Department of Environmental Protection commissioner, announced a plan that would make Sir Thomas Crapper cry with joy: The DEP has planned an upcoming toilet rebate program to swap 800,000 NYC loos with water-saving models.
That program would start in 2013 and would "reduce water consumption, typically one billion gallons per day, by 30 million gallons per day -- a 3% total reduction," the DEP announced. That's because newer, high-efficiency latrines only use 1.8 gallons of water -- compared to as many as 5 gallons on old versions.
If you are interested, you will likely get $125 for switching out your old pot, "covering all or most of the cost of a typical toilet."
