The City of Hood River will conduct sanitary sewer system smoke testing on August 12th and 13th to gain information for future sewer improvements, and some people may notice a distinct odor that results from this testing.  The smoke testing will involve opening and entering manholes in the streets and public utility easements to blow smoke into the sewer system and will occur between 8:00 a.m. and 6:00 p.m. on Thursday and Friday.  A special non-toxic smoke will be used in testing that leaves no residuals or stains and has no effect on plant or animal life.  The smoke has a distinctive odor last only a few minutes where ventilation is adequate.  Should smoke enter your home or business, contact a member of the smoke testing crew working in your area.  The crew member will be able to help and check with you as to where the smoke has entered your building.  To reduce the chance of smoke entering your home/business, pour at least five gallons of water down any infrequently used drain such as a floor drain or unused sink within a few days before the start of the test period.  This will fill up the trap and reduce that potential point of entry.
