CHATHAM COUNTY UTILITIES
JORDAN LAKE WTP
NPDES PERMIT # NC0084093
"SLUDGE DISPOSAL PLAN"
The Jordan Lake WTP is a surface water treatment plant using "Super -Pulsator"
technology and including coagulation, sedimentation, and filtration with a
permitted capacity of 3.0 MGD. Alum Sludge is generated in the treatment
process and is discharged periodically into the sludge lagoon during the
backwashing of the filters. The sludge lagoon decant is then discharged into
Jordan Lake. Sludge removal is performed periodically as the settled sludge level
rises in the lagoon or when the discharge consitituents are above the permit
limits for Total Suspended Residues, Settleable Solids or when the concentration
of Aluminum exceed allowable limits.
In January of 2005 Chatham County completed a lagoon dredging project that
removed all sludge within six -inches of the bottom of the lagoon. This sludge
was pumped from the lagoon to a portable belt press and hauled to a permitted
landfill or discharge site.
It is Chatham County's intent to continue a regular sludge disposal program in
the futurethat will consist of pumping the sludge from the lagoon. The
occurrence of this will be on a minimum of a two-year basis unless the levels in
the lagoon indicate otherwise.
