4. Project Cost-Effectiveness
(165) 3.5 GPF water closets and bed pan washers were replaced with 1.6 GPF water closets and 1.1 / 1.6 GPF dual-flush flushometers (37% water-use reduction)
Rebate: $85,653 (75% of cost)
(260) 1.6 GPF only flushometers on water closets and bed pan washers were replaced with 1.6 / 1.1 GPF dual-flush valve and handle retrofit kits (20% water-use reduction)
Rebate: $17,746 (75% of cost)

“We have to hit efficiency harder than ever. We need another thirty to fifty years to solve the supply problems…but on the demand side we can get way down the field right now”
Mike Davis, Pacific Northwest National Laboratory (PNNL) scientist from Hot, Flat, and Crowded; Why we need a green revolution—and how it can renew America by Thomas L. Friedman.
