To minimize its own water intake Gettysburg College has installed a large number of water-efficient fixtures in its residences and other buildings, and it urges its students and employees to do their part to reduce campus water intake.
Take short (3-5 minute) showers, go trayless at Servo, turn off the faucet, report leaks, and wash clothes in full loads with eco-friendly washing machine settings. However, only 5% of daily water use comes from toilets, taps, and hoses; the rest comes from food, energy, goods, and services.
Purchasing and printing less can reduce individuals’ water footprint in unexpected ways. 2900 gallons of water are used to construct one pair of blue jeans; 80 gallons of water are used to process 2 pounds of paper.
Eating less meat can help individuals reduce their water intake. 500 calories of beef and chicken can be supplied with 1300 and 400 gallons of water, respectively, while 500 calories of rice and potatoes only require 66 and 24 gallons of water, respectively.
