PRINCETON, NJ - After more than two years and 1,400 green handles, Princeton University now features dual-flush toilets in an estimated 95 percent of residence halls, according to The Daily Princetonian.
The toilets, which use 1.6 gallons of water when handles are pushed down but only 1.1 gallons when pushed up, were first installed on campus in 2008, stated the article.
Other water conservation efforts incorporated at the University include the installation of low-flow aerators and shower heads in residence halls, athletic facilities and academic and administrative buildings, which have combined to reduce water usage by 27 percent since 2001, Director of Engineering Tom Nyquist said, adding that the University now uses 63 million fewer gallons of water each year.
"[The reduction] is significant when you consider that [the University has] added students and buildings to the University community," Nyquist explained.
According to the article, Princeton will continue to install dual-flush toilets in the rest of the buildings on campus, including academic and administrative facilities.
