Water damage in Lacey, Washington
Lacey sits next to Olympia in Thurston County and shares its wastewater treatment. The City of Lacey runs its own utilities, so the numbers to call are not Olympia's. The line above also covers Lacey ZIP codes.
Calling soon after you find the water usually leaves more choices. The call goes to an independent contractor.
Lacey ZIP codes on the line
Lacey had an estimated 58,833 residents in the Census Bureau's 2025 figures. Its ZIP codes overlap other towns, so say your street address on the call.
If sewage is backing up
The City of Lacey says to call its Operations & Maintenance Service Center right away: 360-491-5644 on weekdays, 360-704-2740 nights and weekends. Its page says technicians respond to sewer emergencies.
Until crews find the cause, the City says not to run the washing machine or dishwasher, take showers or baths, flush toilets or run water down drains.
Whose pipe is it?
On a gravity sewer, the City says the property owner is responsible for the line from the house to the street sewer main, though it notes there may be exceptions. Where a home is on a STEP system, the owner handles the line to the tank and the City maintains the tank and pump.
Lacey provides drinking water, sewer and stormwater services. LOTT Clean Water Alliance treats wastewater for Lacey, Olympia and Tumwater. More on the utilities page.
Permits and repairs
Lacey's Building Division, part of Building & Zoning, administers and enforces the City's code standards. If a repair involves structural work, ask the Division what applies before the work starts.
