A brief description of any water recovery and reuse systems employed by the institution:
Dining Services recycles water squeezed from its post-consumer food waste and re-uses it on the conveyor, but then it's released to the waste water treatment plant.
None
A brief description of any water metering and management systems employed by the institution:
Principia purchases its water from Illinois American Water Company, where it is filtered and chemically treated to meet “IEPA standards”. Once the water is used by the school, the sewage is piped down to the campus’s very own water treatment facility where the effluent from the Waste Water Treatment Plant is discharged into the Mississippi River. According to our Department of Facilities Chief Engineer, “Our discharge is very high quality and consistently meets the IEPA discharge requirements listed in our discharge permit. We have had only one excursion where an equipment failure caused a release of non-filtered into the water. Our plant has been nominated for Plant of the Year twice in the last five years.”
None
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
The flow rating on all on-campus shower heads is 2.0 gallons per minute (gpm). The U.S. Department of Energy identifies a “low flow” shower head as any fixture that is at or less than 2.5 gpm. On aerators for new sinks, the College is installing fixtures that use 2.2 gpm (which is the minimum requirement for a low flow faucet). All new toilets are rated at 1.6 gallons per flush (consistent with the average low flow toilet).
None
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
---
None
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
There is minimal irrigation on campus. Irrigation is limited to the Chapel Green and athletic fields. Landscaping is largely native and designed to be water-efficient.
None
