Water Systems Save Environment and Money

The high-tech water conservation systems implemented by Cal State Los Angeles and CSU Northridge are paying off – with the delivery of greener communities and lower water bills.

Both campuses recently installed Central Computerized Irrigation Control systems, which measure weather conditions to determine how much water the campus landscape requires. The systems document millions of gallons of outdoor water savings and reduced water bills, contributing to a large-scale conservation of the precious resource.

Cal State L.A. saved approximately 27 million gallons of water over an 18-month period.  On average, that’s more than 2,000 gallons saved an hour. In addition to saving more than $100,000 in water bills since the installation, CSULA was awarded a $50,000 water savings performance incentive from the Los Angeles Department of Water and Power.

Cal State Northridge’s Physical Plant Management department plans on using incentive funds toward water-saving fixtures on campus.  CSUN also plans to analyze its water footprint by merging the CSUN Sustainability Institute with the research of colleagues, grad students and interns.
