Outdoor Water Conservation

​​​​​​​​​​​​​​During the dry summer months, outdoor watering often doubles our community's daily average drinking water demand from 10 to 15 million gallons per day. This places an extra strain on the City's d​rinking water supply. Watering lawns and landscapes accounts for 80-90% of the increase. Nearly half of this water is wasted due to evaporation loss, over-watering and run-off.

Smart Watering Tips​​

  • Follow the voluntary summer watering schedule. Bellingham residents are asked to limit watering from June 1 to September 15 annually to reduce stress on the City's drinking water supply. 
  • The average lawn requires only one inch of water per week to stay green. Overwatering doesn’t improve your lawn’s health and results in runoff and water waste. ​
  • ​Regularly check and adjust your sprinklers. Water only your lawn and not the pavement. See if you qualify for an irrigation controller rebate. ​
  • In order to reduce the amount of water lost to evaporation, the best time to water your lawn is in the mornings between 7am-10am.
  • Mow your lawn with blades set high; grass that is 2” to 3” tall prom​otes a healthier root system and helps retain soil moisture.
  • Consider replacing lawn with native plants to use less water, fewer chemicals, and eliminate mowing.​
  • Use a commercial car wash​ to wash your car. They use water more efficiently by treating it and reusing it.
