Zach and Jason,
I am emailing you to self-report a permit violation for the Town of Benson WWTP in the month of February 2020. As
noted in our recently submitted eDMR,our average daily effluent flow was 1.94 MGD. I included the following
comment as an explanation of how this violation occurred: "Average effluent daily flow greater than permitted
limit. The months of January and February required diverting excess flow to EQ ponds during equipment repairs
(clarifier rehabilitation and grit chamber repairs). Periods of diverted flow coincided with bouts of high rain
volume. This necessitated pumping down EQ ponds to maintain required freeboard level and ensure full treatment of
all wastewater through the plant. (Average influent flow without EQ pond pumping was 1.77 MGD)."
One additional note is that we received 5 inches of rain during the month. We have been repairing our collection
system over the last several months and continue to do so in an effort to reduce our I&I challenges. We have also raised
the matter of needing to start planning our next plant expansion to the town manager, mayor and the board of
commissioners at our annual board retreat, and the discussion was well received. Please contact me if you have any
questions or concerns about this matter.
Thank you,
Brian Leavitt
Superintendent
