The City of Grand Forks will be conducting tests next week to locate sources of storm water that may be flowing into the sanitary sewer system. The firm of Webster, Foster and Weston has been hired to perform smoke testing of sanitary sewers in downtown Grand Forks and on the city's near south side.

The area to be tested is bound by Kittson Avenue on the north, 4th Avenue South on the south, South 3th Street on the east and Cherry Street on the west.

During the tests, specific ares will be pressurized with non-toxic smoke, which will flow out of sewer vents on each building and any storm sewer connections. If a building's plumbing is in order no smoke should enter the building. Often smoke will enter buildings simply because of dry traps in drains. Property owners can pour about a quart of water down all drains prior to testing. Advance notice will be placed on doors of each building one day prior to the day the actual testing will occur.

Testing will take place from September 10th through September 13.
