PORT TOWNSEND — The city of Port Townsend will test its sewer system with smoke and dye this week along Lawrence Street.

Inspections will be between 8 a.m. and 6 p.m. daily.

In a letter sent to residents in the area, the city said some smoke may enter homes or businesses because plumbing appliances are connected to the sewer system.

“You may see or smell smoke exiting from sewer access points, roof vents, manholes, or gutters,” the letter stated. “This is normal and indicates the system is being tested.”

The smoke and dye used are non‐toxic, non‐staining, and safe for humans, pets and the environment, the letter stated.

“Prior to smoke testing, we recommend pouring a gallon of water into open drain traps, basement bathroom drains, and floor drains to help maintain a water seal in the fixture trap. This water barrier will prevent smoke from entering the house during testing,” the city said.

The city is planning a critical infrastructure project to reduce strain on the sewer system and the Monroe Street Lift Station caused by combined stormwater and sewage flows in the Lawrence Street sewer line, from Filmore Street to Monroe Street. The project aims to improve wastewater management, protection of public health and environmental quality, the city’s letter stated.

As part of the early stages of the project, the city will conduct the inspection and assessment of the sewer system.
