We’re in a water crisis. The Governor and the UC President has asked UCSF community to take all actions to save water wherever we can. In response to the UC President Napolitano announced goal of reducing per capita water use by 20 percent by 2020, UCSF has committed to the following:
• Accelerate and expand leak detection program and/or install “report a leak” sticker to engage the campus community.
• Reduce research/agricultural water consumption
• Implement an education outreach water conservation campaign targeting office, laboratories and student housing
• Provide incentive for paying customer that reduce water and fee hikes for users that do not.
• Prioritize energy efficiency retrofit and deferred maintenance projects that also result in water savings.
• Incorporate water-saving guidelines for new facilities into the Campus Standards and Design Guide.
Save water on campus
Turn off the water when you aren’t directly using it. So, turn the faucet off while you are lathering up, brushing your teeth, soaping up your dirty coffee mug, etc.

Lab practices for saving water
When you are in your lab, there are several things you can do to save water.
1. Be mindful of how you are using high quality water (deionized, reverse osmosis, distilled); use it as sparingly as you can because for every four gallon made of these highly processed waters, there is one gallon of “rejected” water sent to the drain. Consider alternatives to stand-alone reverse osmosis and other purification systems. Are they really necessary?
2. Don’t “overwash” dishes/glassware: If you are using a dish- or glasswasher, choose the correct settings for the type of labware you are actually running through, and don’t set dishes/glassware under a running faucet and walk away. This practice wastes tap or processed water unnecessarily. Set up five wash basins: (1) soap and water; (2) tap water rinse; (3) 2, 5, or 10 percent hydrochloric acid rinse; (4) and (5) two separate deionized water rinse basins. Rewash your plastic wares and save money. Steris glasswashers can be set to reuse the last rinsewater for the next wash cycle. Contact Facilities Services to request this.
3. When you are replacing equipment that employs single-pass water cooling, replace it with equipment that uses a closed-loop cooling system, or that can be placed on the campus chilled water loop. UC Davis Chemistry department did this and is saving about 2 million gallons (more than 7.5 million liters) per year of drinking water, in addition to saving money on helium recovery.
4. Eliminate vacuum aspirators, and use a vacuum pump for the same task; this can save about 238 gallons (900 liters) of water per hour of use and avoid the possibility of contaminating water with solvent residue.
5. Evaluate programming cycles loaded onto autoclaves and verify that programs match purpose. Determine which autoclaves/sterilizers are at the end of their life cycle and consider Facilities Service recommendations for energy and water efficient replacements. Ensure that written standard operating procedures (developed from the manufacturer’s instructions) are kept nearby and followed.
6. Re-evaluate habits/practices to ensure they adhere to current best practice standards and avoid developing long-term habits/practices that have been exaggerated over time. (Example: setting timers on autoclaves to wash longer than necessary is a common habit that becomes common practice over time so that lab staff no longer are adhering to more efficient standards)
Save water at your residence
