Water Main Break Repairs and Road Closure Update

Crews worked through the night to repair a water main break near the 8300 block of East Mercer Way. Water service has been restored to approximately 50 affected homes. This break required replacing a section of pipe, which is complex and time consuming to repair. The main has been flushed and the water is safe to drink; there may be some discoloration at first and it should gradually improve. Impacted residents are encouraged to run their water to speed up this process. Contact City of Mercer Island Customer Service at (206) 275-7600 or customerservice@mercerisland.gov to report any issue. 

There is a second water main break near the 7700 block of East Mercer Way (near Clarke Beach Park), which is impacting five homes. Crews are on scene and beginning to complete the repair. These five homes may experience intermittent service disruption while the emergency work is completed.  

The East Mercer Way roadway between SE 76th St and the north end of Clarke Beach Park sustained damage due to the water main break and will remain closed. A geotechnical engineer has evaluated the site and has recommended that the roadway remain closed until it dries out and is further evaluated. This road closure is anticipated to be in place for at least a week. See the attached map for recommended detours.  

Updates will be provided as more information becomes available.
