  1. BIF greywater meter - update

    Associated Project(s): 

    The greywater piping system at BIF uses potable water, but in FY19 F&S started tracking the water consumption that goes through the greywater pipes. The meter for that water consumption is not in the Energy Billing System because it does not get billed separately.  It is on the DDC system as 1206-W3. The meter base ID is 1206-W3. Usage can be requested from accounting or email Robbie Bauer.

  2. BIF Greywater Meter Recommendation - approved

    The Water and Stormwater SWATeam recommendation to install a real-time water meter on the greywater pipes in the Business Instructional Facility has been approved by F&S leadership.  This project will proceed with funding from the Student Sustainability Committee and F&S Utilities & Energy Services.

  3. archived info - previous project description

    Associated Project(s): 

    The Business Instructional Facility (BIF) was designed for future use of greywater, which is raw (untreated) water. Although the building is fed from the potable water supply, there is separate piping for the urinals and water closets in the building. Utilities does not yet have a greywater system in place. When such a system becomes available, the connection in BIF that serves its fixtures can then be transferred to the greywater supply.

  4. Water001 BIF Greywater Meter recommendation - Transmittal

    Following the completion of iWG assessment of Water001 BIF Greywater Meter, the recommendation was transmitted to the Facilities & Services (F&S) department on July 12, 2017.

  5. Water001 BIF Greywater Meter recommendation - Assessment with comments

    The iCAP Working Group (iWG) met on December 20, 2016, to discuss and start the assessment of SWATeam recommendation, Water001 BIF Greywater Meter. The iWG's official comment on the recommendation was:

    "A permanent real-time water meter should be installed on the greywater piping system in BIF, and the collected data should be made available in the Energy Billing System and through an online dashboard."

  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."
