Per Student Flow Reduction Approval
Lincoln County
Dee Freeman
Secretary
On February 16, 2008, the Pretreatment, Emergency Response and Collection Systems (PERCS) Unit received a
flow reduction request for the proposed consolidation of the West Lincoln County High School and West Lincoln County
Middle School wastewater flows. The combined wastewater flow will be treated by West Lincoln County High School
WWTP (Permit No. NC004 1246).
Wastewater flow data (from June 2007 through May 2008) and water usage data from both schools (from June
2006 through April 2008) was provided and analyzed by central office staff. Based upon this data the Division hereby
approves a reduction in flow for the consolidation of the two school's wastewaters into the existing high school WWTP to
7.5 gallon per student.
Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater flows exceed the
effluent limits defined in the NPDES permit for the treatment facility or exceed the capacity of the sewers downstream of
any new sewer extension or service connection(s).
If you have any questions or comments regarding this matter, please contact Deborah Gore at [phone] ext.
593, email [[e-mail]].
