Fayette County’s Department of Fire and Emergency Services will conduct a test of outdoor sirens throughout the county at 9 a.m. on Feb. 5 as part of Georgia’s Severe Weather Awareness Week.

The sirens are the ones used to warn residents about impending dangers such as tornadoes and flooding. Officials are asking residents not to call 911 if they hear test sirens. The test will be postponed until Feb. 7 if there is actual severe weather on Feb. 5. Two weeks later, the city of Senoia will conduct a smoke test of sanitary sewer lines starting the week of Feb. 17. The nontoxic smoke is used to detect places where excess water is entering the sewer system during rain storms.

Senoia residents are asked to run water through all sinks, tubs and floor drains, especially those not used regularly, and to fill plumbing P-traps. Smoke may be visible from sewer vents and in streets or yards, but will not normally enter buildings unless the structure has a plumbing problem. Running water to flush the drains will clear the smoke.
