A brief description of when and why the water use baseline was adopted:
Since this is the first time Sac State is completing the STARS report, the performance year was chosen based on the most recent 12 month period prior to starting work on the STARS report. Sac State started working on the STARS report in September 2015. The baseline year was determined by choosing the next 12 month period prior to the performance year so that the data being looked at for both date ranges would include the last 2 years to include the campus’ most recent sustainability efforts and achievements.

Water recycled/reused on campus, performance year:
0 Gallons

Recycled/reused water withdrawn from off-campus sources, performance year:
0 Gallons

A brief description of any water recovery and reuse systems employed by the institution:

A brief description of any water metering and management systems employed by the institution:
Sac State is currently in the design phase to install approximately 167 smart meters which consist of the following: smart gas meters, smart water meters, and smart Btu meters which will all communicate to the existing EIS software.

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

A brief description of any weather-informed irrigation technologies employed by the institution:
Sac State converted the existing sprinkler heads to low-gallon sprinkler heads, integrated all irrigation controllers to the Rainbird Maxicom irrigation control system. The Maxicom system is now connect to the campus weathers station to automate weather related shut-downs and start-up to conserve irrigation.
The irrigation water used is from the campus Well Water system. This project would reduce the amount of ground water depletion by reducing our irrigation needs.
