A brief description of when and why the water use baseline was adopted:

UC Irvine's water use baseline (3 year average for fiscal years 2005-2008) was established in the UCI 2013 Water Action Plan based on University of California Sustainable Practices Policy guidelines.

Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Since the 2013 Student Aff airs has continued to promote personal water conservation in housing anddining areas. Residence halls have implemented a water conservation program emphasizing peer-to-peer education through UCI’s Earth Rep’s program. To date, student representatives have educated over 400 residents on the importance of water as a resource and the personal impact students can have on water supply through behavior changes. In 2017 close to 2,000 shower hangers were distributed to undergraduate students through the program. In addition to the shower hangers Student Housing developed signs that give water-savings tips in bathrooms, laundry, and kitchen areas. Staff also provide opportunities to learn about drought tolerant landscaping through succulent planting events and volunteer turf removal projects. Future opportunities include education on green products that help protect waterways and a pilot study of shower timers. Peer to Peer Engagement Student interns engage the campus community throughout the year teaching water conservation awareness while giving advice on reducing personal water consumption. Interns use a variety of outreach techniques including displays and games while also interacting one on one with peers. Interns also use social media to advocate for water conservation through infographics and instructional videos in an eff ort to reach a broader audience. Foam Rub Rinse Campaign Facilities Management has also provided outreach to the campus community encouraging conservation of water through the Foam, Rub, Rinse campaign. Signs have been placed across the campus core encouraging this practice.

A brief description of the institution's water recovery and reuse initiatives:

Reclaimed water (tertiary treated blackwater) has been used for landscape irrigation on campus for more than 40 years. UCI works collaboratively with the Irvine Ranch Water District (IRWD), a pioneer in treating wastewater for reuse for agriculture and landscape irrigation. UC Irvine's blackwater is locally treated one-half mile away from campus at the IRWD Michelson Treatment Plant. Through IRWD the campus reclaims approximately 34% of blackwater produced on campus for landscape irrigation resulting in the conservation of more than 230 million gallons per year of potable water supply. Partnering with IRWD, UCI is currently converting the campus central plant cooling towers to recycled water use. Expected to be completed spring of 2018, this project will reduce potable water use on campus by an estimated 80 million gallons per year.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

UCI has completed Phase 1 of an extensive campuswide plumbing retrofit program, replacing all pre-1994 plumbing fixtures (toilets and urinals) with high-efficiency fixtures. Phase 1 has resulted in annual savings of 14.8 million gallons per year. The next phase of this program will involve replacement of targeted post-1994 fixtures (urinals with gpf greater than 1, toilets with 1.28-1.6 gpf, and faucets with gpm exceeding 0.5 gpm) which will result in an additional 10.6 million gallons per year in savings.
