RESTROOM WATER EFFICIENCY PROJECT
• University of California, Irvine
• Water Efficiency
• Fred R. Bockmiller, Principal Engineer, PE, CEM, LEED®-AP
PROJECT DESCRIPTION
• Given a suggestion to retrofit waterless urinals in campus
restrooms with the highest usage, the project team set out to
reduce water consumption and help “green” the restrooms on
campus
– Urinals were only one aspect. The project also included:
•
•
•
•
Toilets with dual flush valves
High Efficiency Toilets (HET)
Reduce towel usage through signage
Signage for the water conserving fixtures (enables people to do the
right thing)
• The campus-wide retrofit is ongoing. Initial phases took six
months to accomplish. As funding permits additional phases will
be added.
PROCESS
• A leader in sustainability and energy conservation, UCI Facilities Management
established a group of dedicated individuals in the early 1990’s that looks at all
aspects of our operation to find ways of reducing costs and environmental impacts.
• This project flowed out of our analysis of the various options available to us for
water conservation and our ongoing dialog with our water supplier the Irvine Ranch
Water District.
– Used information gathered from extensive discussions in email list service regarding
end-user experiences
– Initial focus on urinal retrofits broadened to include high efficiency toilets (HET) and
dual flush valves
– Involved the plumbing staff in plumbing decisions and obtained “buy in”
– Chose Zurn over Caroma due to simpler installation
– Conducted side-by-side trials of low flow (one gallon per flush) and ultra low flow (one
pint per flush)
– Noted which fixture was chosen when the conserving fixture was labeled
– Discussed user perceptions of quality
– Solicited applicable rebates and incentives
TECHNICAL INFORMATION
• Selected Zurn Model Z5615 (wall hung) and Z5665 (floor mount)
toilet
– 46 wall hung units and 14 floor mounted units installed so far
– Annual water savings estimated at 1,100,000 gallons
• Project cost $35,000 (labor and materials)

Total Incentive $25,500
Net Project Cost $8,500
Annual Savings $3400; Simple pay back on total cost is 10.3 years
Net simple pay back is 2.5 years
TECHNICAL INFORMATION
• Used the Zurn Model Z5798 “The Pint” Urinal
– 70 units installed so far
– Annual water savings estimated at 2,800,000 gallons
• Project cost $64,000 (labor and materials)

Total Incentive $32,500
Net Project Cost $31,500
Annual Savings $8,500; Simple pay back on total cost is 7.5 years
Net simple pay back is 3.7 years
• Porcelain portions should last 40 years
• Hardware should last at least 10 years
TECHNICAL INFORMATION
• Used water industry methods to calculate savings
– http://www.mwdsaveabuck.com/toilet.htm
• Metering in campus buildings not really accurate for purpose of before
and after comparison (e.g. urinals small part of laboratory process use)
• Per urinal savings estimated at 39,000 gallons per year
• Per toilet savings estimated at 19,000 gallons per year

SIDE BY SIDE
THE STICKER IN ACTION
BARRIERS
• As with many projects in state-funded organizations, the water
efficiency project faced funding issues from the start
– Working with our local and regional water suppliers achieved
significant incentives
• Because many of our fixtures were more than 35 years old, the
“standard” connection set up was not standard (3” old versus 2”
standard)
– At our request, the manufacturer developed an adaptor that allows
us to retrofit these fixtures in place of the old “boat anchors”
• Perception that waterless urinals were the “be-all” and “end-all”
solution to saving water with urinals
– On site experience of waterless urinals
ACCOMPLISHMENTS
• Examined multiple technologies (waterless, one-pint)
• Surveyed buildings to find the busiest restrooms on campus as
determined by our custodial staff
• Used notification stickers and placards right on the fixture
• Combined deferred maintenance with water conservation
• Annual water savings of 3,900,000 gallons. Equal to 4 large
“Olympic” swimming pools.
LESSONS LEARNED
• Establish a good working relationship with the water conservation
experts at your water supplier. Meet with them face to face and
discuss all aspects of your operation.
• Leverage their expertise in navigating funding paths
• This type of project can be implemented with minimal financial
impact by using all available incentives
• Be open to alternatives
• Question directives to “implement technology x”
