Plant Narrative & Sludge Management
Maury Sanitary District operates a 0.225 MGD wastewater treatment plant. The plant flow is of
a domestic and commercial nature. There are no industrial dischargers into the town's collection
system.
Wastewater flow to the treatment plant is screened by a mechanical bar screen. A manual grit
removal chamber follows the headworks. After preliminary treatment, the flow is directed to the
Oxidation ditch for secondary treatment. Flow is then split into two secondary clarifiers for
solids settling. The effluent of the clarifiers is combined and flow to the
chlorination/dichlorination chamber for disinfection.
After dichlorination the effluent flow is measured and post aerated before discharge to
Contentnea Creek.
