University of California Irvine, California RESULTS AT A GLANCE NIAGARA PRODUCTS INSTALLED Stealth® 0.8 GPF Toilets Earth® 1.5 GPM Showerheads 0.5 GPM Aerators REPLACEMENT DETAILS 558 fixtures* were replaced including both 1.6 and 3.5 GPF toilets WATER SAVINGS Water reduction 9.5 million gallons saved annually ANNUAL FINANCIAL SAVINGS $43,000 9.5 Million Gallons of Water Saved Each Year at Student Housing Complexes In 2011, a water conservation program was developed through a partnership between the Irvine Ranch Water District (IRWD), the University of California at Irvine (UCI), and Niagara Conservation Corporation. The plan was to install high-efficient fixtures in student housing complexes at UCI and the IRWD would document water savings. It was hoped that the impact would not only result in conservation efficiencies at the university, but would also validate technologies and methods that could be rolled out and successfully implemented within the IRWD. Installations began in summer 2011 and were completed in 2012. The project was so successful that the water saved could fill 475 swimming pools! UCI, home to six student housing communities owned by the university, hoped this project would contribute to their goal of reducing water consumption 15% below their 2007 baseline by 2014. Reducing water usage by an average of nearly 40% at three of their student housing complexes allowed them to get closer to reaching their ultimate goal. Due to this success, the IRWD, which spans 181 miles in densely populated Orange County, California, expanded the initiative to a district-wide Multi-Family Direct Install program. Implementation of this program will help them meet their targets of reducing the per capita water use 20% by 2020, reduce reliance on imported water, and realize long term cost-effective conservation programs. Water-Efficient Products Installed *Fixture=toilet, showerhead, aerator www.NiagaraConservation.com IRWD documented water savings derived from plumbing fixture retrofits in three different UCI student housing communities: Campus Village, Middle Earth and Verano Place. The fixtures installed were Niagara Conservation’s ultra-high-efficient Stealth 0.8 GPF toilets that replaced both 1.6 and 3.5 GPF toilets, 0.5 GPM bathroom faucet aerators and 1.5 GPM showerheads. ©2013 University of California Irvine, California PRODUCT SUMMARY Project Scope Housing Complex STEALTH ® 0.8 GPF First and only toilet to achieve a powerful, quiet flush using only 0.8 gallons of water. Total Buildings Total Fixtures* Total Students Year Residents Per/Fixture Constructed Middle Earth 4 88 332 4.232000 Verano Place 12 300 600 2.001984 Campus Village 25 200 800 4.001980 l l Saves up to 15,000 gallons of water per year. The Stealth at work: When flushed, as water fills the tank and inner chamber, air is forced down through a transfer tube and into the trapway. When flushed, a powerful vacuum from the depressurized trapway clears the bowl with a one-time, powerful flush. l Monitoring and Study Groups Meters were installed on two identical buildings from each community, while one building from each community was not retrofitted. Monitoring was conducted for a minimum of three months and once the monitoring was completed, the control buildings were then retrofitted. Water Savings By Housing Complex EARTH MASSAGE SHOWERHEAD ® Housing Complex 1.5 GPM l Uses up to 40 percent less water than standard showerheads. l Saves nearly 11,000 gallons annually. Three showerhead spray settings – needle, massage and combination. Patented pressure-compensating technology guarantees a feeling of great force while using less water, consistent flow rate regardless of water pressure. l 0.5 GPM l Uses 70% less water than a standard 2.2 GPM aerator. Produces forceful streams at a reduced flow rate that minimizes the amount of energy needed to heat water.

No cost to UC Irvine for pilot study; IRWD paid for all installations. l l The retrofitted buildings received new Niagara plumbing fixtures that were WaterSense labeled. l Maintenance calls were reduced. l The project continues to save nearly 9.5 million gallons of water per year. l *Fixture=toilet, showerhead, aerator Annual Project Gallons Total Water per Day Lifetime Percent Savings Savings AD Savings Reduction (Adjusted for per AF in Metered Student Occupancy) (10 yrs) Water Use Middle Earth Campus Apart. 3.5 Village l TAMPERPROOF HIGHEFFICIENCY AERATOR Gallons Existing per Day Toilet Total Students Savings Housing Flush Packages per per Type Volume Installed Package Package l l Water usage was reduced by an average of nearly 40% for the three complexes.
