49 Interior Water Solutions 47% of the water used in commercial buildings is used in the restroom, mostly by toilets.

50 plumbing fixtures are you?? What water saving familiar with?

51 Ultra-low faucets and showerheads

52 Ultra-low-flow faucet aerators

53 Dual flush toilets and flushometers

54 Waterless Urinals 3 Year Simple Payback

55 Waterless Solutions Generated savings per 1000 square feet per year, according to an EPA building study. Waterless Units Less cost than traditional ones, thereby eliminating the incremental first costs, according to an EPA building study. Waterless Urinals Percent reduction in building water use. $4.53 $282 14%
