Project Name: Wastewater Treatment and Collection System Improvements
B. USDA ARCHITECT/ENGINEER'S WRITTEN ANALYSIS AND RECOMMENDATIONS
CPAP Comments
The (TWSA) owns and operates an existing 0.200 million gallons per day (mgd) capacity
wastewater treatment plant (WWTP) in the unincorporated Cashiers area of Jackson County.
The facility discharges treated wastewater effluent to the Chattooga River. Current and
requested wastewater flows (held allocations) currently exceed the 0.200 mgd capacity when
summer seasonal wastewater flows are considered. Therefore, there is an immediate need for
increased wastewater collection and treatment capacity in the Cashiers service area. Due to the
Outstanding Resource Water (ORW) stream classification of the Chattooga River, the North
Carolina Department of Environmental Quality (NCDEQ) has indicated that it will not approve
an expansion of this existing discharge. TWSA has obtained a second National Pollutant
Discharge Elimination System (NPDES) permit for the additional treated wastewater effluent
discharge necessary to meet this demand.
In order to meet existing and future demands TWSA proposes to construct a second WWTP at
the eastern edge of the service area which would discharge treated wastewater effluent into
the Horsepasture River. The construction of a second WWTP, would take place on the
easternmost parcel of the service area, which was previously purchased by TWSA for the
purpose of constructing this alternative. The construction of this alternative would also involve
the replacement of two pump stations and the construction of 7,840 linear feet (If) of force
main and 8,155 If of gravity sewer.
The PER details the overall benefits of this proposed alternative. The proposed project appears
to meet the long term needs of the system. The proposed project costs appear reasonable and
modest compared to other recent projects completed in this area. I recommend this project
for Rural Development funding consideration.
