TWSA Plant # 2 is operated under the authority of the following permit, as issued by the North Carolina
Dept. Of Environment and Natural Resources: NC0020214 NPDES Discharge Permit
TWSA Plant # 2 discharges from one outfall into Scott Creek which is classified Class C-Trout waters in
the Little Tennessee River Basin. The plant process is a conventional activated sludge process with a
design capacity of 0.5 million gallon/day. The plant consists of the following unit processes, manually
cleaned bar screen, aerated grit removal, activated sludge with secondary clarification and chlorination and
dechlorination facilities. The facility is currently in the design/permitting phase to renovate the equipment.
This renovation will not increase capacity but will replace outdated equipment and improve efficiency.
The average daily flow at the facility during the year 2021 was 0.117 mgd. This represents
23.4% of plant capacity and was a 9.2% decrease from the avg. daily flow during 2021. The highest
monthly average in 2021 occurred in March 2021 and was recorded as 0.161 mgd. This represents 32.2%
of total plant capacity and was a 28.8% decrease from 2020. The highest daily recorded flow in 2021 was
.316 mgd and occurred Apr 1st, 2021. There were zero days during 2021 when the daily flow exceeded
plant capacity.
This plant produced 254,000 gallons of waste sludge during 2021. This sludge was hauled via tank truck to
TWSA Plant #1 for treatment. These residuals totaled 21.65 dry tons and represented 6% of the total
residuals generated by the Authorities facilities.
Overall performance of the TWSA #2 wastewater plant for the calendar year of 2021 was excellent. There
were no violations of permitted monthly, weekly or daily limits during the year. On average, there
was a 97.3% reduction in the amount of pollutants in the water after treatment.
This facilities permit was renewed on July 1, 2018 and expires Oct 31, 2022.
