Water restrictions in Spokane, WA — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Spokane uses the Spokane Valley-Rathdrum Prairie Aquifer. Water conservation program encourages odd-even watering, avoiding midday irrigation, and efficient systems. Mandatory restrictions activated during drought.
Spokane draws water from the Spokane Valley-Rathdrum Prairie Aquifer, a sole-source aquifer shared with Idaho. The city runs a year-round water conservation program under SMC Chapter 13.04. Standard guidelines encourage odd-address watering on odd calendar days and even-address on even days, with watering before 10 AM or after 6 PM to reduce evaporation. New turf installations are discouraged during July-August peak demand. During declared drought or water shortage emergencies, mandatory restrictions can limit watering days, prohibit ornamental fountains, ban washing of hard surfaces, and impose surcharge rates. Rebates are available for WaterSense-certified irrigation controllers and conversion to drought-tolerant landscaping. Spokane Aquifer Joint Board coordinates regional protection.
During mandatory restrictions: warnings first, then fines $100-$500. Chronic over-use can trigger flow restrictors or service disconnection for extreme cases.
