1. Purchase Price: less expensive to purchase and install than flush urinals because they have no flushing mechanism. All that is required is a drainage outlet, typically less than an hour to install, and seconds to install the cartridge.
2. Operating Costs: save 100% of the water going through urinals and 100% of water and sewer charges—both of which will certainly rise in the future.
3. Maintenance Costs: reduce maintenance to a periodic changing of the cartridge and quick cleanup as with traditional urinals. Eliminate costs associated with stuck or broken valves from normal wear and vandalism. Reduce pipe cleaning since lines remain free of calcification as no hard water is running through them. Reduce energy costs associated with transporting water to and from urinals.
Example of cost savings: Here at the NIH there are approximated 15000 employees and approximately 50% are male. For this example, I conservatively guess there are 500 urinals (we have 60 buildings on campus) and assume 2 uses per male per day. Each flush uses approximately 1 gallon and cost (per 1000 gallons) $3.50 for the water and $3.50 for the sewer operating 365 days per year results in a savings of 5475000 gallons of water per year and water and sewer costs of $38,325. Add the cost of standard urinal maintenance $37,500 ($50/urinal/year) and subtract the cost of replacement cartridges for the flushless urinal ($52,702) for a savings of $23,123 and over 5,000,000 gallons of water annually
