You may notice our seasonal voluntary watering schedule signs around Bellingham. These serve as a friendly annual reminder to help reduce outdoor water use during the dry summer months. Outdoor watering can increase our community’s water use by up to 50%, and much of that is lost to evaporation, over-watering, and run-off.
While our drinking water supply is stable and we don’t anticipate shortages, high summer demand places extra strain on our water treatment plant. Following the voluntary watering schedule helps keep our system running efficiently all season long.
From June 1 to September 30:
💧Skip watering on Mondays
💧Odd-numbered addresses: Water only on Sundays, Wednesdays, and Fridays
💧Even-numbered addresses: Water only on Tuesdays, Thursdays, and Saturdays
Want to save even more water? Consider letting your lawn go dormant. It naturally greens up again when cooler, wetter weather returns.
City water customers can also take our Water Conservation Pledge to receive free outdoor water‑saving tools at cob.org/conserve.
