Less Wasteful Flushing

A little plastic device called the “AquaSaver” is saving the Marriott Corporation about $3.4 million per year in water bills, with an estimated three-month payback. Tests have consistently found savings of

1⁄2 to 1 gallon (2 to 4 liters) per flush, with remarkably few problems, and no change in the dynamics of the flush. Marriott tested the device for three years before proceeding with their plan to install it in all their 480,000 rooms (280,000 are now in place). “This is the only thing that we’ve ever found to put in our toilets with confidence that it won’t cause problems,” reports Marriott’s Van Vandevender.
