Description of Wastewater Treatment Plant:
The City operates and maintains a 5 million -gallons -per -day (MGD) extended aeration plant. It has an
automatic bar screen and grit chamber with an emergency bypass channel, 3,500 gallon caustic tank for pH
control, dual train aeration basins and dual train secondary clarifiers. The disinfecting system is comprised
of dual vacuum feed chlorinators for use with 1-ton chlorine cylinders. The chlorine contact chamber has
a 30 minute detention time for an effluent flow rate of 5 MGD. The plant also de -chlorinates using dual
S02 cylinders. Sludge is conditioned in one of the two aerobic digesters with combined capacity of 500,000
gallons. The plant also utilizes a 1.5 million gallon sludge holding tank.
Performance:
January to December
TSS % Removal= Less than 85% (83%) January 2022 we had received high flows on Mondays from
rain events. We have also been training new staff on procedures for high flow events and
collecting samples.
Effluent TRC= June 6-9, 2022, we had issues with our TRC readings being high. I contacted Ori on
6/6 & 6/7 to explain that we were having issues and we contacted Piedmont Chlorinator to come
check both days as well. we also had the Lab bring 2 different meters to verify they were reading
accurate.
Chronic Toxicity= August 2022 we failed testing, we resampled in September & October 2022 and
passed both.

Subject: 2022 WAR City of Belmont Wastewater Treatment Plant
Enclosed you will find the 2022 Wastewater Annual Report for the wastewater
treatment plant for the City of Belmont. Please note that the influent flow from April 29-
May 2, May 30-June 21, and July 9-Dec 31, 2022 was affected by the automatic bar
screen being down and in bypass. TSS % Removal for January 2022 were less than 85%
(83%) we had received high flows on Mondays from rain events. We have also been
training new staff on procedures for high flow events and collecting samples. Also
Effluent TRC for June 6-9, 2022, we had issues with our TRC readings being high. I
contacted Ori on 6/6 & 6/7 to explain that we were having issues and we contacted
Piedmont Chlorinator to come check both days as well. we also had the Lab bring 2
different meters to verify they were reading accurate. Chronic Toxicity for August 2022
we failed testing, we resampled in September & October 2022 and passed both.
If you have any questions, please feel free to contact me at 704-825-3791.
Sincerely,
Tanya S. Carter
WWTP Superintendent/ORC
