Smoke Testing: Info to Know

The City of Gahanna is continuing the study and assessment of the sanitary sewer system in the western portion of the City (see map below).  The City has contracted with EMH&T to assist in performing engineering and field services for this project.  The field work includes smoke testing of sewers, dyed water testing and sewer televising.

Over the next several months, it may be necessary for representatives of EMH&T to access existing sewer easement areas, typically located in backyards and sideyards, to perform this work. Representatives of EMH&T may require access to sanitary sewers and manholes via private property. If necessary, an attempt to notify the homeowner will be made prior to any work on private property. For the smoke testing phase of work, it should not be necessary for the workers to enter any homes. Prior to performing field activities adjacent to private property, EMH&T will provide a door hanger notice approximately 48 hours in advance with additional instructions.

During significant rainfall events you may observe members of the EMH&T project team in the project area. They will be observing the impacts of wet weather on the sanitary sewer system. Recording these impacts may require the crew to respond during non-business hours. If you have any questions or concerns, please don’t hesitate to ask for identification.

If you have any questions regarding this work, please call Marci Bland of EMH&T at (614) 775-4237 or Jim Turner, City Water Resources Engineer, at (614) 342-4004.  Your cooperation is greatly appreciated.
