Saving water is easy...and free!

Free water-saving showerheads are available through the City of Redmond Public Works Department.

Free showerheads can be picked up at City Hall, Utility Billing at 411 SW 9th St., or at the Public Works Department at 243 E. Antler Avenue, Suite 100.

Efficiency Benefits* showerhead

Non-conserving showerheads use 5 to 8 gallons per minute (gpm), consuming up to 40 gallons of water for a single five-minute shower. Simply installing a high-efficiency showerhead and faucet aerator will save about 7,800 gallons of water per year in an average household. Low-flow heads save more than 12 gallons per shower (a savings of 44% over non-conserving showerheads). Ultra-low-flow heads conserve even more, using only .8 to 1.5 gpm, reducing the average five-minute shower's water usage from 40 to 7.5 gallons. By reducing the demand for hot water, a household reduces the amount of energy needed to heat the water. In this way, a low-flow showerhead helps to cut the emission of 376 pounds of climate-changing carbon dioxide each year and a faucet aerator helps to prevent the release of 83 pounds of carbon dioxide per year.

HOW TO SAVE WATER OUTDOORS


In the City of Redmond, we use 6 times more water in the summer than we do in the winter.  The culprit? Landscape irrigation. By improving the way we use water outdoors —and choosing the right plants—we can collectively reduce our summer water usage.

You can decrease your summer water use and save money on your water bill by:

  • Improving irrigation practices
  • Reducing water waste
  • Managing your landscape

EFFICIENT IRRIGATION

Changing the way you irrigate can have a measurable impact on your water consumption levels. Here are some ideas for improving your irrigation efficiency:

  • Invest in water-saving technology such as smart irrigation controllers. A smart irrigation controller tells your sprinkler system when to turn on and off based on local weather and landscape conditions. These irrigation controllers enable watering schedules that better match the water needs of plants.

  • Invest in rain and soil moisture sensors, and high-efficiency sprinkler heads.

  • Avoid using sprinklers when it’s windy to prevent water from blowing onto areas where water is not needed.

  • Inspect your irrigation system for leaks.

  • Adjust sprinkler heads to keep water away from the street and sidewalks.

 WATER SAVING IRRIGATION TECHNOLOGIES

   Weather-based Controllers use sensors, including thermostats, to calculate the amount of water that evaporates from the soil surface and is used by the plant. These systems adjust watering based on local weather and landscape conditions.
   Rain Sensors turn off the irrigation system when they detect rain. Most systems have a disk that swells when it gets wet, triggering a switch that turns off the irrigation system. Rain sensors can be retrofitted on already installed sprinkler systems.
 

 Soil Moisture Sensors use a probe to measure soil moisture near the roots of plants and turn the irrigation system on and off to maintain desirable soil moisture conditions.

REDUCING WATER WASTE

Irrigating between 7 pm and 7 am is recommended.

Why is it better to irrigate in the early morning or the late evening?
Loss of irrigation water to evapotranspiration increases in the middle of the day.

Evapotranspiration = Evaporation (water that evaporates from surfaces) + Transpiration (water that plants release)

Transpiration makes up 10% of the moisture in the atmosphere. When plants are watered excessively, they respond to the higher water moisture and release more moisture into the atmosphere.

Factors that Determine Transpiration Rates

  • Temperature: Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. Higher temperatures cause the plant cells controlling the openings (stoma) that release water to the atmosphere to open, whereas colder temperatures cause the openings to close.
  • Relative humidity: As the relative humidity of the air surrounding the plant rises, the transpiration rate falls.
  • Water evaporates more easily into drier air than into more water saturated (humid) air.
  • Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate. Wind moves air around, causing more saturated air close to the leaf to be replaced by drier air.
  • Soil-moisture availability: When moisture is lacking, plants can begin to senesce (premature aging, which can result in leaf loss) and transpire less water.
  • Type of plant: Plants transpire water at different rates. Some plants that grow in arid regions, such as cacti and succulents, conserve precious water by transpiring less water than other plants.

HOW TO REDUCE WATER LOSS TO EVAPOTRANSPIRATION

  • Only irrigate between 7 pm and 7 am.
  • Aim your sprinklers low to the ground to avoid loss to wind and evaporation.
  • Keep water on the landscape to avoid loss to evaporation from paved surfaces.
  •  Don’t just “set it and forget it.” Check and adjust your sprinklers when weather conditions change.
  • Set your mower blades higher. Taller grass loses less water to evapotranspiration.

OTHER WAYS TO REDUCE WATER WASTE

  • Don’t wash, driveways, sidewalks, or other impervious surfaces—sweep instead.
