For the next few hours, it may look like there’s trouble at Arlington’s Water Pollution Control Plant. But don’t worry, because it’s only a drill.

The Arlington County Fire Department will assist the County with conducting a safety drill at the facility from 10:00 a.m.-2:00 p.m. The activity will center around the Methanol Facility at the southwest end of the WPCP, near S. Glebe Rd. A number of fire department vehicles will be on scene and there will be audible alarms sounding.

The WPCP has spent several years going through a massive upgrade and renovation period. Most of the renovations are expected to be finished this summer.
