The year 2024 marked the forty seventh year of operation of
the Middleborough Water Pollution Control Facility.
Operating under authorization granted jointly by the
United States Environmental Protection Agency and the
Massachusetts Department of Environmental Protection,
the facility, an advanced tertiary treatment plant, meets
strict limits for various water quality parameters before
discharging to the Nemasket River.
Among the most basic measurements of wastewater
quality are CBOD and TSS.
Our permit allows for a maximum of 7.0 mg/L CBOD and a
maximum of 7.0 mg/L TSS.
During calendar year 2024 the facility discharged an
average CBOD of 2.5 mg/L at 98.8% removal eficiency and
A total of 1,845 sewer connections are served with an
estimated population equivalent of 7,608 persons, or
approximately one-third of the Town population.
In addition to the direct connections to the sewer system,
the facility treated about 2.07 million gallons of septage
from residents who have on-site disposal systems.
All residents use the plant, directly or by maintaining their
septic system, this fact should encourage everyone to
have an interest in the facilities operations.
We are proud of our operating record and the protection it
afords the Nemasket River. The facility is in compliance
with all permit limits.
I wish to thank the plant staf for their excellent work and
role in achieving this performance record.
