PLNU launches new water conservation plan?Point Loma Nazarene University (PLNU), which has already embarked on several environmentally friendly projects and programs across campus, has now gone even more green, said university officials.?This spring, PLNU’s Student Government Association (SGA) officially agreed to discontinue the use of trays in the university’s cafeteria. This change is expected to reap benefits by helping the campus conserve energy and water usage, said officials.?Tracy Le, SGA director of communications, said the university uses an average of 1.5 gallons of water to wash one rack of trays, with each rack holding about 10 trays.?Since about 2,500 guests on average visit the PLNU cafeteria daily, university officials said that equates to about 250 racks per day. Without trays, PLNU will be saving around 375 gallons of water per day and 2,625 gallons of water every week. With the cafeteria now going completely trayless, PLNU officials said they will be conserving around 10,500 gallons of water each month. n
