    Subject: This aternon meeting

    In the interests of making the most of our time, here are my top line goals. The first one is based on Lance Schideman suggestion. Three and four are again based on Lance and Marys suggestions.

    We might even want to suggest a water reuse goal with timelines. Not sure what the basis would be but if we want a zero water campus, we can calculate precipitation over some area and assume that it satisfies a portion of our needs; the rest would come from reuse (both effluent as well as stormwater). The stormwater could be integrated with landscape and will be the residual after accounting for evapotranspirtion.

    Any water features as part of the landscape would then be integrated with heat sink needs as campus, possibly creating an year-round landscape, maybe even a temperate rainforest in the Mid-west!

    Goals

    1. Overall reduction
      1. in line with ICAP 2010
      2. Normalized levels of 20,000 gallons per weighted campus user in 2020 and 16500 gallons per weighted campus user by 2025
      3. Normalized  levels of 42 gallons per total buildings sq. ft (buildings + laboratory space) by and 36 gallons per sq. ft. in 2025 (question to Stephanie on these numbers)
    2. Undertake bottoms-up approach to estimate end-use for campus using best practices to determine realistic goals achievable by water conservation alone
    3. Recognize water reuse as an essential component to continue reductions in fresh water demand on campus beyond 2025; initiate planning activities to increase water reuse on campus 
    4. Integrate the physical and natural elements of campus topography to reduce water demand on campus and facilitate reuse

  2. SITES system

    Associated Project(s): 

    Dear Keith and Water Team:

    Here is a link to Sustainable Sites Initiative, now called SITES rating system. SITES has a long history, but the short story is that this is a robust and leading tool for advancing landscape performance. It not only a tool but also a certification program. It is/will be adopted by USGBC to inform the sites credits for LEED. In many ways, it was a response to LEED really not getting at the potential for site systems themselves. It could be added to iCAP's recommendations for renovations and new construction. 

    Just as with LEED, it went through some growing pains, particularly challenging was documenting pre-design conditions to demonstrate performance and sustainability improvement. After multiple years of pilot projects and testing, version 2 has just been released. It can be used with or without a building or other structure within the site, making it a great tool for our campus. 

    A colleague of mine at Conservation Design Forum in Elmhurst, IL has been a key participant in its development, and he would be a fantastic additional to our external consultant group.

  4. Water SWATeam using Google Drive

    Associated Project(s): 

    Hello SWAT Water,

    It was nice to meet all of you this morning, I am excited to be part of this group! We have a lot of great ideas already that I am excited to see implemented. I have created a google drive folder which I will be placing all of our minutes and documents in. I have shared it with everyone, so please inform me if you haven't received the folder in your drive account (it should be labeled "SWAT Water Minutes and Documents").

    In the folder, I have uploaded our minutes from this morning and also included any supplemental documentation that we have received thus far for your convenience, including the charge letter and various templates that were emailed from Ben. I also uploaded the power point that I brought up during the meeting. I produced this power point last year when I was contracted by West Point to do some research on Low Impact Development implemented on campuses east of the Mississippi. Hopefully this can be an asset to flip through to see some things other campuses are doing in the east and midwest to reduce their impact on water supply and quality along with links to find more information on the individual projects.

    I hope everyone has a great weekend and I will see you all next Wednesday at noon!

    Cheers,

    Danielle Thayer

  5. suggestion for water conservation

    Subject: oxijet water nozzle

    A suggestion from someone in the UI physics department.

    http://www.felton.co.nz/?sid=2152

     

    The Felton Oxijet™ volumises the stream with air giving you a more luxurious shower.

    Traditional flow restrictors work by simply reducing flow and pressure, whereas the Oxijet™ uses flow energy to draw air into the water stream.

  6. potential student challenge

    Hi Water SWATeam,

    One of the potential water-related projects for campus could be this student competition: http://water.epa.gov/infrastructure/greeninfrastructure/crw_challenge.cfm.

    What do you think?

    Thanks,

    Morgan

    Water purchasing at about 3.25/100,000 gallons. Plus you have to pay for sewer water as well. In other areas it is more expensive.  Decrease water consumption Find uses for non-potable waterHandle storm water quality and quantity Kishore. How do we compare to other schools? Be the leader as far as water per square foot. ICAP baseline to improve. Is one perspective? We are there now.  Eliana Brown storm water protection.  Most buildings have meters now. About 99% ISTC study. There so much more to do on campus.  CEE 398 PBL water report.  Irrigation usage. Wasn't in the billing system.  Barrier to grey water.
