City of Vacaville Schedules Sewer System Smoke Test Inspections Sept. 25–30
The Vacaville sewer system will undergo smoke testing in September to pinpoint areas where storm water or ground water may be entering the sewer collection system. The City of Vacaville Utilities Department will conduct testing in two areas Sept. 25–30, from 8 a.m. to 3 p.m. The smoke candles used are nontoxic and the public should not be alarmed if they notice smoke.
Crews blow air and smoke into the sewer system through a manhole in the street and monitor where it escapes from the system. Smoke testing is an efficient and cost effective way to identify both leaks, as well as where property owners may have incorrectly connected drains into the sewer system instead of the storm drain system. The City conducts these tests because reducing storm water intrusion into the sanitary sewer system can eliminate the need for costly treatment plant expansions and the need for larger sewer mains.
The smoke test will occur in two areas. The community of Elmira is the first general area scheduled for smoke testing. The second general area scheduled for smoke testing is the Brown Street area bordered by Markham Avenue to the north, Depot Street and Markham Avenue to the west, Mason Street and Interstate 80 to the south and southeast, and Callen Street to the east.
Residences and businesses will receive a notification letter with a map in the mail one week prior to conducting the actual smoke test. This notice will explain more about the smoke testing program. Each residence or business will also receive a handout a few days prior to the smoke test.Please contact City Utilities Department staff at (707) 469-6400 if you have any questions.
