MLWSA Field Staff will be inspecting Air Release Valves (ARV's) in the MLWSA collection system beginning Wednesday, June 26, 2019. You may see our white trucks along with a contractor tanker making multiple stops in your area. Workers will be removing groundwater from the ARV manholes, inspecting the ARV's, and replacing any ARV's that have failed. Failed ARV's are returned to our shop for reconditioning. The work is physically demanding, but the MLWSA Staff is up to the challenge. Inspections should be completed by the end of July, 2019. Please use caution when driving near our moving work zones.
