Transcript of UO Sustainability - Water

Collect rainwater in cisterns for irrigation and toilets Replace fixtures within buildings - Parking lot runoff - Does operation of the central power station affect the millrace ecosystem? How do we begin to decide how sustainable our water use is on the University of Oregon campus? Considerations: How does our water use compare to other campuses? What is the effect of our campus on local riparian ecosystems? Proposed Sustainability Metrics Gallons of water used per year per scaled campus user How are we doing according to these metrics? Percent of irrigation provided by collected rainwater Gallons of water used per year per square foot of buildings Percent of campus water usage that is submetered Percentage of campus irrigation that is on an automated, evapotranspiration-based system (MAXICOM) Health and biodiversity of the millrace ecosystem
(How to measure? IS the millrace an ecosystem?) Gallons of water used per year per square foot of buildings Rainwater Context MAXICOM Coverage How do we use water? - remote digital metering to economize on labor
- hire additional staff to consolidate and clarify water data and conduct campus water audits
- integrate into curriculum -- ENVS? Architecture? LArch?
- Roger van Gelder at LCC
- incorporate athletics water use into utility data
Exact percentage unknown - percentage of campus irrigation provided by collected rainwater
- annual gallons of water use per year per square foot
- annual gallons of water use per year per scaled campus user
- percentage of campus irrigation that uses the MAXICOM system - percentage of total campus water use that is submetered
- percentage of campus water use that is submetered by category
- percentage of campus paving that is pervious
- diversity and health of Willamette River ecosystems adjacent to campus Incorporate water use for campus and individual buildings into "dashboards," available in the lobbies of buildings or online Percentage of irrigation provided by collected rainwater? Establish standardized metrics and regularly share water use performance data with peer institutions
- Oregon State?
- LCC?
- PSU? Percentage of campus water use being submetered How does our water use compare to peers? * Submetered percentage does not contain the fraction of campus buildings that are submetered because the percentage of total water use that building use constitutes is unknown By building square footage By total campus water use Water How can we improve? How is our water use changing over time? University of Oregon, 2009 Chart derived from 2005 Exergy report: Water Benchmarks for Office and Public Buildings (http://www.environment.gov.au/settlements/publications/government/water-benchmarks.html) Zero? Change landscaping on parts of campus to species that don't need water in the summer Use the MAXICOM system to provide regular digital reports on irrigation water use Expand use of the MAXICOM irrigation system to all of campus, including athletics You're Invited:
Public Presentation
14 May, 2-4pm
Location TBA Recommendation 1:
Submeter Campus Water Use Why: How: Benchmarks: Recommendation 2:
Reduce Campus Water Use Why: How: Benchmarks: Recommendation 3:
Consolidate and Clarify Campus Water Use Data Recommendation 4:
Make Water Use Data Available to Campus Users and the Public Why: How: Benchmarks: Recommendation 5:
Share Water Use Data with Peer Institutions Why: How: Benchmarks: Why: How: Benchmarks: Recommendation 6:
Reduce Negative Effects of Campus Stormwater Runoff on Local Riparian Ecosystems Why: How: Benchmarks: - using less water costs less
- dry summers
- why waste water? We don't know how we're using more then 90% of our water on campus Can we state unequivocally how much water is being used on campus and for what purposes? - difficult to access
- multiple bills, departments
- manual meter reading - improve campus transparency
- empower campus users
- encourage student projects to improve campus water use efficiency - is campus and individual building water use available online?
- is water use in individual buildings available on dashboards within those buildings? - would allow us to better gauge how efficiently we are using water
- allows us to share our own lessons and learn from others' lessons - have we decided on common water use data that we and our peer institutions will collect?
- have we scheduled a regular annual water use summit? The university is very close to the Willamette River and is responsible for the stormwater coming from its campus - campus permeable paving assessments performed by landscape architecture students?
- riverbank ecosystem health assessments performed by biology students? We don't really know... Buildings? Irrigation? Leaks? Central Power Station? Swimming Pools? Just do it. Total campus water usage
