Notice of Sewer Smoke Testing in Damascus

Beginning Aug. 10, 2026

Washington County Service Authority (WCSA) will begin sanitary sewer smoke testing in the Damascus community starting Aug. 10, 2026. This testing is part of WCSA’s ongoing efforts to maintain the reliability and efficiency of the sewer system, and to identify locations where stormwater or groundwater may be entering the sewer lines.

 During smoke testing, a non-toxic, odorless smoke is introduced into the sewer system through manholes. The smoke travels through sewer pipes and may exit through vent stacks on homes or other structures, allowing technicians to identify leaks, cracks or improper connections in the system.

 The smoke used is safe, non-staining, and non-invasive, and it poses no health risk to residents, pets or property.

 Residents may see smoke coming from roof vents, yard drains or manhole covers during testing. This is normal and simply indicates that the sewer system is functioning properly. The testing process does not require crews to enter homes or businesses.

 This work helps WCSA reduce inflow and infiltration, prevent sewer overflows and ensure the long-term performance of the wastewater system serving the community.
