From The Denver Post (Bruce Finley):
They’ve asked lawmakers to consider setting a statewide toilet standard of 1.28 gallons per flush. Toilets account for about a quarter of household water use, and the new standard could save 44,000 acre-feet of water a year by 2050…
New toilets sold today use a maximum of 1.6 gallons per flush, in compliance with Environmental Protection Agency limits set in the 1990s. But in Denver, an abundance of homes still have old-style fixtures that use an average volume of 3.14 gallons per flush, according to Denver Water’s latest “end-use study.”[…]
State Sen. Gail Schwartz, D-Snowmass Village, said the proposal will be considered along with other water-conservation measures that have become a top priority for Colorado. “This not only saves water consumption overall, but it also provides an opportunity to reduce the amount of water sent to wastewater treatment,” she said. “If consumers can save money and also work toward saving water, I think this might be popular.”
Toilet manufacturers backed the measures because they are eager for more people to buy new products. Plumbing Manufacturers International “drove” the passage of flush limits in California and Texas, PMI executive director Barbara Higgens said. “People typically only replace a toilet when something goes wrong,” she said. “We really like them to embrace the new technology, just as they would a computer or cellphone.”
