Denver Water offers free placards for hotels to post in rooms, encouraging guests to reuse towels and lines to help save water. See the sample placards:

Contact Denver Water at conservation@denverwater.org to request the signs.

Water use benchmarks

Use these water-use guidelines to make sure you are using water efficiently.

Bed and Breakfast 7,925 gallons (30 cubic meters) per bed space per year
2-3 star 10,566 gallons (40 cubic meters)  per bed space per year
4-5 star 21,133 gallons (80 cubic meters)  per bed space per year


  • Guest rooms
    • Install low-flow or high-efficiency toilets.
    • Install showerheads with a flow of 2.5 gallons per minute or less.
    • Install sink aerators to reduce the flow to 1.5 gallons per minute.
    • Participate in linen reuse programs.
  • Public amenities and staff rooms
    • Install low-flow or high-efficiency toilets.
    • Install urinals that flush 1 gallon per flush or less. 
    • Install sink aerators to reduce flow to 1.5 gallons per minute or less.
    • Equip ice machines with air-cooled condensers. 
    • Install aerators on mop sinks to reduce each sink’s flow to 2.5 gallons per minute.
  • Heating and Cooling
    • Eliminate single-pass (once-through) cooling water in air compressors and other equipment by using chillers, cooling towers or air-cooled equipment.
    • Minimize blow-down on cooling towers and boilers by using a conductivity controller.
  • Laundry
    • Always run full loads of laundry.
    • Install ozone systems to reduce water detergent and energy use.
  • Kitchens
    • Install aerators on kitchen sinks to reduce each faucet’s flow to 2.5 gallons per minute or less.
    • Use 1.6 gallons-per-minute pre-rinse spray valves to rinse dishes. Contact Denver Water for a free, professionally installed pre-rinse spray valve. Call 303-628-6009 for more information. Water savings potential: 50,000 gallons per year; energy savings potential:  330 therms for gas hot-water heating per year.
    • Use boilerless steamers that consume three gallons per hour or less. Water savings potential: 162,000 gallons per year; energy savings potential: 26,000 kilowatt-hours per year.
    • Use energy-efficient flake or nugget machines instead of cube ice machines. Water savings potential: 38,000 gallons per year; energy savings potential: 2,500 kwh per year.
    • Defrost food in the refrigerator instead of under running water. Water savings potential: 65,700 gallons per year.
    • Use dishwasher equipment that meets efficiency standards set by the Consortium for Energy Efficiency and install steam doors to reduce evaporation. Water savings potential: 450,000 gallons per year.
    • Use dishwashers and C-line conveyors with electronic sensors, door switches, etc., to stop water from flowing when they’re not washing.
    • Replace worn and missing water jets on dishwashers.
  • Irrigation and Landscape
    • Follow Denver Water’s watering rules (no watering between 10 a.m. and 6 p.m., and no more than three days a week).
    • Do not exceed 18 gallons of water per square foot of irrigated areas.
  • Policy
    • Include water efficiency in the company’s environmental policy statement.
    • Delegate water efficiency responsibilities.
    • Establish quantitative water efficiency goals and communicate those goals to employees.
    • Inspect for leaks regularly. 
    • Use a sub-meter and monitor for excessive water consumption or leaks.
