KEY FACTS & TERMS
On average, a restaurant uses 300,000 gallons of water every year.
Only 3% of water on Earth is fresh water.
By serving water upon request only, you could save up to 2 gallons of water per glass (due to unused water and dishwashing)
Gallons per minute (GPM): Also known as a "flow rate", this is the calculation to determine the efficiency of spray valves, aerators, etc.
WATER CONSERVATION TIP
Install high efficiency pre-rinse spray valves and low flow aerators.
Instead of using a regular pre-rinse sprayer for your dishwashing, install one that is high efficiency. The GRA recommends pre-rinse sprayers with a flow rate of ≤ 0.45 gallons per wash (GPW). Installing one pre-rinse sprayer could save you $75 per year.
Install low flow aerators on your hand and non-fill prep sinks. The GRA recommends low flow aerators with a flow rate of ≤ 1.5 GPM. Each aerator could save you $500 per year!
WHERE IS WATER USED IN RESTAURANTS?
Encourage your favorite restaurant to become a Certified Green Restaurant®
If you don’t want water, tell the wait staff when you are seated
Choose a vegetarian or vegan menu item, which requires less water to produce than meat
