Water & Stormwater SWAT Meeting Minutes 3/16/2017
Updates on BIF Greywater Meter application. Discussion on Cooling Tower COC and "Zero" blowdown systems.
Updates on BIF Greywater Meter application. Discussion on Cooling Tower COC and "Zero" blowdown systems.
Updates on BIF Greywater Meter, Increase Cooling Tower COC, and Design Center Greywater Piping recommendations. Discussion on the development of water use dashboard.
Keith Erickson, Morgan Johnston, Jason Jones, and Stephanie Cash attended the first annual Urbana Stormwater Public Meeting on February 15th, 2017. The City of Urbana Engineering Staff led a discussion with community members on the stormwater management practices required for the City’s National Pollutant Discharge Elimination System (NPDES) permit. The City of Urbana owns and operates a Municipal Separate Storm Sewer System (MS4) which is required by the US Environmental Protection Agency to implement minimum control measures to target and improve stormwater quality. The minimum control measures include public outreach and education, public participation and involvement, illicit discharge detection and elimination, construction site runoff control, post-construction runoff control, and pollution prevention and good housekeeping.

Olivia Webb and Morgan Johnston met with Meghan Killinger and Stephanie Cash to provide an introduction to the SWATeam clerk responsibilities.
Review of pending recommendations: BIF Greywater, Increase Cooling Tower COC, Design Center Greywater Piping. Discussion on possible edits to the SWAT/iWG process. Student members will submit proposal to Student Sustainability Commision for apermanent meter to measure BIF greywater use. The Water SWATeam will meet every other week and will have a joint meeting with the Agriculture, Land Use, Food, and Sequestration (ALUFS) SWATeam this semester.
The iCAP Working Group (iWG) met on December 20, 2016, to discuss the SWATeam recommendation, Water003 Design Center Greywater Piping. After some discussion, the iWG rejected this recommendation.
See SWATeam recommendation Water003 Design Center Greywater Piping here.
The Water and Stormwater SWATeam submitted a recommendation to the iWG stating,
"We recommend that a small tonnage (< 700 tons cooling capacity) stand-alone cooling tower on campus operating at a water concentration cycle of less than 2.5 be operated using softened water under high pH/high silica conditions to demonstrate near zero blowdown operation."
See attached the SWATeam recommendation, Water002 Cooling Tower Increase COC, complete with comments from all the Water and Stormwater SWATeam members.
The Water and Stormwater SWATeam submitted a recommendation to the iWG stating,
"Monitoring the water usage in the Business Instructional Facility (BIF). Specifically, both the total water use and the amount of water used by the raw water system should be measured and the data made available to the campus community.
BIF is unique in that it was constructed with a separate raw water system that conveys non-potable water to be used for purposes such as flushing toilets. While the system is in place inside the building, it was never connected to an outside source of non-potable water. Use of non-potable water for purposes such as toilet flushing, landscape irrigation, cooling, etc. is recognized as a sustainable practice (e.g., Asano et al, 2007; EPA, 2012). Data to quantify the impact this could have on water use at UIUC, however, is largely unavailable. Metering the raw water system at BIF would provide data about the temporal total and non-potable water demand at a typical campus class/office building. These data would be valuable to consider whether such systems should be considered in future campus construction and renovation.
F&S installed a temporary meter to measure the flow to the raw water system and operated this meter for approximately one month (April – May 2016), so this recommendation has already been demonstrated to be feasible. However, because building usage is highly variable over the course of an academic year, we recommend that this should be a permanent installation. We also recommend that the data be made available to the campus community to encourage consideration of such water reuse options."
See attached the SWATeam recommendation Water001 BIF Greywater Meter complete with comments from all the Water and Stormwater SWATeam.
The Water and Stormwater SWATeam submitted a recommendation to the iWG stating,
"We recommend that the Siebel Design Center should be designed to include plumbing to supply non-potable water to be used for toilet flushing. The system could be connected to the potable water supply until such time as a viable non-potable source (e.g., the campus raw-water lines) is available. At that time the non-potable lines could be connected to the non-potable source at a small expense. We also recommend that a meter be installed to monitor the amount of water delivered to the non-potable system and that these data be made available on the Dashboard operated by Facilities and Services."

Meeting focus: review of goals for SWATeam and ideas/comments on how to accomplish objectives
Meeting focused on drafting recommendation studies to submit to the iSEE working group.
Recommendations included Business Instructional Facility greywater piping system and infrastructure for raw water piping in the design center.
Topics of discussion for the Water and Stormwater Team meeting included recommendations studies, the function, and role of the iCAP working group, expectations for the SWATeam, metering at BIF, and the use of greywater in the Design center (a new building on campus).
Meeting focused on the function of the SWATeam and resources available for the team to utilize. The team reviewed recommendation studies submitted by the Water team in the past.
Topics of Discussion included poster for Campus Sustainability Celebration, Feasibility Studies submitted in the late Spring of 2016, and the Goals of SWATeams.
Discussion focused on finalizing information for Poster for the Campus Sustainability Celebration in October of 2016.
The main focus of this meeting was preparing the information for a poster. The poster will be presented at the Campus Sustainability Celebration in October of 2016. The team's objectives and any updates on projects will be included on the poster.
This was the first meeting of the Fall 2016 semester. Discussion was focused on non-potable water and meeting schedule for the rest of the semester.
The charge letter was sent to FY17 SWATeam members, noting that the clerks will be reaching out to help schedule meetings for the fall.
Here is a copy of the project I created for Jen's class last semester
Enjoy
