Green Tool Kit: Water Conservation: Urinals

Santa Barbara Green Businesses must replace all urinals flushing at greater than 1.0 gallons with urinals flushing at less than 0.5 gallons, or waterless urinals, as shown in Figure 1.

Your water utility may have a rebate program for high efficiency urinals.

HEUs: High-Efficiency Urinals (HEUs) are defined as fixtures that function at 0.5-gpf or less. Based on data from studies of actual usage, these urinals save 20,000 gallons of water per year with an estimated 20-year life.

Urinal retrofit kit: The flush volume in typical 1.0 gallon per flush urinals can be retrofitted with a .5 gpf diaphram kit. This is a great, cost-effective way to turn the ultra-low flush urinal into a high-efficiency urinal for around $50 a fixture.
