Total wastewater discharged:
321,048,835 Gallons

Wastewater naturally handled:
205,000 Gallons

A brief description of the natural wastewater systems used to handle the institution’s wastewater:

The University Greenhouse bioremediation wetland was sized to filter up to 500 gallons per day .

At Aspen Hall, a greywater system collects & treats an average of 62 gallons per day. This greywater is then sent to 11 first floor student room toilets for flushing.

Note that under current Colorado water law, large greywater systems are not permitted. The Aspen Hall system was permitted to allow for research in this area, but larger systems would require changes to “COLORADO REVISED STATUTE 37-87-101 (2014) TITLE 37. WATER AND IRRIGATION, WATER RIGHTS AND IRRIGATION, ARTICLE 87. RESERVOIRS”
