CITY OF REI DSVI LLE
WATER TREATMENT PLANT
NPDES PERMIT NO. NCO046345
NARRATIVE DESCRIPTION OF DIAGRAM
Raw water is pumped from Lake Reidsville to the sedimentation basin, where chemical
addition occurs for solids settling. After sedimentation, the water is chlorinated and
filtered. Following filtration, additional chemicals are added to the water and then
stored in a clear well. The filter back wash water is discharged to the sludge lagoons.
Also, when the sedimentation basin is cleaned, the solids are discharged to the sludge
lagoons. Supernate from the lagoons are discharged to an unnamed tributary of Little
Troublesome Creek. The solids from the sludge lagoon are pumped to the sand drying
beds and hauled to a local landfill.
SLUDGE MANAGEMENT PLAN
The City of Reidsville's water Treatment Plant is currently dewatering and stockpiling
sludge on sand drying beds. When disposal is required the sludge is taken to a local
landfill.
