• The City and its contractor have worked out an alternative method of cleaning/inspecting the anaerobic digesters. Therefore, the parking lot outside of the WWTP gates will remain open during the summer other than when some sandblasting and painting in the vicinity occurs. We will post notices when the sandblasting and painting is scheduled.

Although products like facial tissues, dental floss, cotton swabs, and kitty litter may flush down the toilet, they can cause clogged pipes for you and your neighbors. Watch the video below to find out more, from the City of Spokane Department of Wastewater Management.
