The City of Bellevue installed a new sewer pipeline in the Newport Shores neighborhood. This work will help reduce the risk of sewer backup during large storm events.
The project completed construction in the summer of 2023.
Why is this project needed?
During large rain events, excess storm water can seep into the aging sewer system through small cracks. This rain infiltration can overwhelm the capacity of the system and lead to the risk of wastewater backups in low-lying homes. Bellevue crews previously managed this problem by using vacuum trucks to transport excess wastewater to the Newport Pump Station. Relying on this manual operation was not ideal or a long-term solution.
Project solution
Rather than crews manually transporting wastewater flows during rain events, the construction of a new sewer “force” main will improve both capacity and reliability of the current sewer system by moving wastewater flows away from under-capacity areas with the use of portable pumps.
Project benefits
With the new sewer line, residents in this neighborhood will see improvements in wastewater management and environmental protection, reduced risk of sewer backup, and safer access into and out of the neighborhood during severe storm events.
