WALLA WALLA -- The next round of work to replace aging water and sewer lines in the city will begin Monday.
The replacement project will be on Bryant Avenue from Howard Street to the cul-de-sac to the west. This will be the second project of the Infrastructure Repair and Replacement Plan approved by the City Council in April.
In a release, project manager Ronald Rooks said the project is expected to take about 10 weeks to complete. Access to homes in the area will be maintained by the contractor and minor interruptions to traffic at the Howard Street intersection may occur near the end of the project for final hook-ups and paving.
Premier Excavation of Richland was awarded the contract for the project April 28 after offering a low bid of $488,860.62.
Information on the project is available on the city's website or by calling 527-4537.
The project will include replacement of about 1,200 feet of water and sewer lines and rebuilding the road surface and portions of curb and gutter. Ramps to allow access by disabled pedestrians will also be installed at the intersection of Bryant Avenue and Howard Street along with other work to help control traffic.
Rooks said the Bryant Avenue section was selected as a infrastructure replacement project due to the age and advanced deterioration of the pipes in that area and how they interact with other sections of the surrounding water and sewer system.
Pipes in the area range from 40 to 70 years old and videos of the sewer lines show a large amount of groundwater seeping into the sewer main.
Conversely, potable water and untreated wastewater leaking out of broken pipes could affect the quality of groundwater, an issue of particular concern due to the proximity of Garrison Creek.
