WHAT: Sanitary Sewer Smoke Testing
WHEN: Beginning Tuesday, Aug. 3, between 8 a.m. and 5 p.m. We expect the work to take about a week.
WHERE: Downtown Marysville, generally bordered by 5th Street (south), BNSF railroad tracks (west), 73rd Place NE (north) and 47th Avenue NE (east) – see map
WHY: To identify any defects in the public sewer system
HOW: ADS Environmental Services will push synthetic smoke up the sewer pipe to find any connections to storm water systems. To do so, they will open maintenance holes within the roadway and on private properties. Crews may need to enter yards to access manholes. They will carry official identification and will not need to enter residences or businesses.
During testing, you may see white or gray smoke coming from vent pipes on the roofs of homes and businesses. This may indicate a break in the sewer lines. The smoke is non-toxic, leaves no residue and creates no fire hazard. It may smell similar to burning paper and can cause minor throat irritation if inhaled.
Smoke should not enter any buildings except for those will possible plumbing defects or dry drain traps. If smoke enters your home or business, please notify the smoke testing crews in the immediate vicinity or call city Project Manager Matt Eyer at 425-760-6464.
