Re: NOC-2020-DV-0237
The Town of Mount Pleasant experienced an SSO from our Summer Street
pump station on April 30, 2020. This station is a dry pit station with suction lift
pumps and air discharge lines for priming. On this day, there was a significant
rain event that occurred in which the area saw 3 inches of rain, (measured
approx. 1 mile away), in a period of 3 hours. Significant inflow to the station
surpassed the pumps capability to maintain control. Both pumps were in good
working order at the time.
This station has only a small reserve capacity to handle an inflow event such as
this. The basin serving this station has been smoke tested and CCTV'd multiple
times in the past and no major inflow contributors could be identified. The age of
the station combined with the lack of reserve capacity contributed to this event. It
has been recommended to replace or upfit this station and/or add an EQ basin to
prevent future occurrences such as this. The containment area at the station
retained most of the spill and was pumped back into the wet well and all debris
were removed from the area and limed for odor control. Also, as clarification, in
the NOV it stated the duration to be 35 minutes. I believe this was a typo during
the data entry process, the CS-SSO paperwork sent to Tony Parker states 3
hours for duration of spill.
If there are any questions related to this spill, feel free to contact our Public
Works Dept.
