October 11, 2019 (El Cajon) – If you see smoking sewer lines in El Cajon over the next month, don’t worry!  The City of El Cajon plans to test portions of the sewer system using a non-toxic, non-staining artificial smoke substance. The test will help locate possible leaks, defects, improper connections and the source of storm water infiltration into the sewer system.
