Greenwood testing sewer lines by blowing smoke

GREENWOOD, S.C. (AP) — Greenwood’s sewer service is truly blowing smoke.

The Index-Journal of Greenwood reports the Greenwood Metropolitan District is testing sewer lines Monday in some communities by using a fan to blow smoke through them.

The tests will help locate where rainwater and groundwater are entering the sewer system. The excess water can overload lines and wastewater treatment plants.

Officials say the smoke is made specifically for the testing and is not harmful to humans, pets or plants. Residents could see smoke exiting vents on their property.
