Downtown sewer overflow tank requires another $2 million to complete, City says

This brings the total project cost to $33.3 million

SPOKANE, Wash. – City of Spokane’s combined sewer overflow tank will require another $2 million to complete.

Marlene Feist, Director of Communications and Marketing for the City, told 4 News Now that the extra cost is to ensure the stability of the overflow tank, which is built into the hillside above the Spokane River downtown.

The extra cost will also involve the plaza built above the overflow tank, which closed shortly after opening in late October.

Feist reports that work on the project will finish sometime in the summer, and that the tank will not be connected to any drainage systems until then. The plaza itself will remain closed during the winter, due to earlier concerns that de-icer might damage the concrete floor of the space.

The total price of the overflow tank project now sits at $33.3 million.
