TWSA #4 WWTP
(NC 0087602)
Sludge Management Plan
Due to low initial flows at the Whittier WWTP no sludge has yet been
produced from the process. The sludge generated in the activated
sludge process at the facility will be stored in the aerobic digestor
(capacity 30,000 gals) before being hauled via tank truck to the
Tuckaseigee Water and Sewer Authority's sludge handling facility
located at: TWSA Plant #1
1871 North River Rd.
Sylva NC 28779
The sludge from the tank truck will be dumped into one of two aerobic
digestors at the TWSA Plant #1 facility. A sample of the sludge will be
obtained from the tanker on each day that a hauling event occurs. This
sampling allows calculation of the total tons of residuals hauled from
the Whittier WWTP. After being mixed and stabilized via air from
diffusers installed in the digestor, the sludge is dewatered via the 1.2
meter Komline-Sanderson belt press. Dewatered sludge is then
disposed of by either hauling to a designated landfill or by being treated
to a Class A Residual in the rotary batch dryer as manufactured by
Fenton Environmental Technologies. Treated residuals are then
disposed of under the authority of non-discharge permit # WQ0005763
as issued by NC Dept of Environment and Natural Resources.
