In response to Sanitary Sewer Overflow that occurred on July 29, 2022, I would state that
incident was a result of a pressure switch transducer failure our crews responded as quickly as
possible to correct the situation. An instrumentation contractor was contacted immediately and
the pump were hand operated till a replacement transducer was installed.
There is a planned expansion of the McCoy Creek Pump Station that will scheduled to be
installed by mid 2025. This expansion will create a redundant wet well chamber and
replacement of the existing 45 HP pumps with 100 HP pumps and a new large diameter parallel
forcemain with updated SCADA control, these improvements should greatly reduce a repeat
incident. We are looking to upgrade the SCADA control later on this year.
I would ask for some consideration in the civil penalty because the incident was virtually
unavoidable with the existing control equipment in place.
