A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Santa Rosa Junior College promotes water related behavior change through all staff emails and its Eco-Cub department Certification. Additionally there is signage that promotes Water Bottle Filing Stations around campus. The all staff emails ask staff to be water conscious and to report any and all leaks they see around campus grounds or in their respective buildings. The Eco-Cub asks them to do the same thing and helps departments replace restroom aerators with new low flow aerators.


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

Santa Rosa Junior has a long history of working with Municipal partners to use recycled water for landscape irrigation. More recently new buildings are being outfitted with dual plumb technology so process cooling water needs and toilets can be flushed with recycled water. At the main district campus the college is building a 50,000 gallon cistern to recapture around 6,000,000 gallons of water a year for irrigation and toilet flushing use.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

The Santa Rosa Junior College whenever possible has changed out faucets urinals and toilets to low flow fixtures. Additionally it has changed old stand alone chillers and cooling towers with High energy efficient Air Source chillers that do not require water. The college has also implemented a electromagnetic water treatment system for it's cooling tower system which reduces both water and chemical usage.

Additional documentation to support the submission:

The Shone Farm campus sits on 365 acres of land which includes a large functioning farm, and forest. Due to the fact that reclaimed water is used for farm land irrigation, portable water usage is significantly lower than total water usage. The Shone Farm Campus uses about 35 million gallons of reclaimed water a year. There is also some reclaimed water used at our Windsor campus which uses about 2,000 gallons a year.

Additionally, our portable water usage has been reduced at our Windsor Public Safety Training Center by modifying our skid pad training. As a part of the police training curriculum officers in training must learn how to drive while skidding. Previously this training was conducted on a lot which has been wet down. This practice has been replaced with a cars that have been retrofitted to replicate driving on wet roads without the use of water.
