CSA-1 Smoke Testing
Periodically, the Del Norte County Service Area No. 1 (CSA-1) conducts smoke testing to identify potential issues within the sanitary sewer collection system. During testing, smoke is typically visible at roof vents and locations where there are broken or damaged sewer mains, laterals, cleanouts, or prohibited connections. Identifying and correcting these problems helps reduce groundwater and stormwater infiltration, which can otherwise consume valuable pipe and pump capacity and increase the volume of wastewater requiring treatment at the City of Crescent City’s wastewater treatment plant.
The smoke the CSA-1 uses to smoke test is non-toxic. It is similar to smoke used in special effects at parties, festivals, and concerts.
It is the goal of the CSA-1 to inform the public of smoke testing prior to and while it is occurring.
Example:
In September of 2025 smoke testing occurred and lasted about a week. Public noticing included a portable changeable message board (about a week ahead of the start), public information bulletins (about a week ahead of the start), social media (about a week ahead of the start), and noticing at occupied properties (about a day to a week ahead of getting there). Additionally, emergency services were notified each day when smoke testing was occurring. The following content circulated in the community:
