Optional Fields

A brief description of the institution's water-related behavior change initiatives:

---

A brief description of the institution's water recovery and reuse initiatives:

A cistern captures the rainwater off the Admissions & Alumni building and this water is used to irrigate the landscape.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Seattle University recently invested in water conservation by replacing the shower heads and faucet aerators in the Xavier, Campion, Bellarmine, Murphy, and Chardin residence halls with low-flow fixtures. Estimates indicate that SU will reduce 25% or about 4 million gallons of water for residence halls per year.

We have also replaced aerators in all public bathrooms on campus to 0.5 GPM.

Seattle University has a Resource Management Plan that codifies water conservation practices in our facilities: https://www.seattleu.edu/media/facilities-services/UPDATED_Seattle-University-Resource-Management-Plan.pdf

Data source(s) and notes about the submission:

--Reporting year for this credit: FY18 (therefore numbers are different from PRE-4 and PRE-5. PRE-4 and PRE-5 data is for FY19).

--Note that the gross floor area of building space (performance year and baseline year) in this credit OP21 is SU's operational boundary GSF (not the institutional boundary GSF): we exclude leased buildings from our count because we do not receive any utilities-related data for those buildings (that is entirely managed by another company) nor do we control changes or improvements related to the building’s utilities.

--Note that for student residents, we adjusted our numbers for the performance year: the number of students resident on-site in FY18 was 2,094.0. But because the water data we report on in this credit OP21 only includes the buildings that we own and manage (operational boundary; excluding any leased buildings), we subtracted 300 students from the total number of student residents (that is the combined capacity of two residence halls that SU leases and for which we do not report any water data in this credit OP21).
The baseline year numbers for student residents should not change because the two residence halls were not in use before FY10.
