  2. Stormwater Utility Fee overview

    The University pays a stormwater utility fee to both the City of Urbana and the City of Champaign.  The fee is based on total impervious area that drains into city-owned storm sewers. If stormwater drains into university-owned sewers then directly discharges to a receiving stream, there is no fee assessed.

    • The current rate for the City of Champaign is $5.24/3,478 sq ft.
    • The current rate for the City of Urbana is $5.14/3,100 sq ft.

    There are credits and incentives that the university can apply toward the stormwater utility fee. By maintaining compliance with the university’s Municipal Separate Storm Sewer System (MS4) National Pollutant Discharge Elimination Systems (NPDES), the university receives a 5% credit from each city. Additionally, each city has their own Credit and Incentive Manual (attached) which provides an opportunity for the university to reduce their stormwater utility fee by reducing the impact of the runoff from their properties by methods such as installing sustainable storm water practices that allow stormwater to infiltrate into the ground. The manuals have specific guidelines on how to calculate the credits based on the particular stormwater practices that are employed.

  3. Inaugural Stormwater Public Meeting

    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.

  4. Water & Stormwater SWATeam Meeting Minutes 2/2/2017

    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. 

  5. Water003 Design Center Greywater Piping recommendation - Denied

    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.

  6. Water001 BIF Greywater Meter recommendation - Submittal

    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."

  7. Water003 Design Center Greywater Piping recommendation - Submittal

    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."

    See attached the SWATeam recommendation, Water003 Design Center Greywater Piping, complete with comments from all the Water and Stormwater SWATeam members.

  8. Water002 Cooling Tower Increase COC recommendation - Submittal

    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.

  9. 10/21/16 Water SWATeam Meeting Minutes

    Associated Project(s): 

    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.
