Point Of Discharge: WWTF outfall
Corrective Action Taken: After receiving notice of the first violation of 11,000 ecoli we deep cleaned our u.v bank, replaced all bulbs and the system seemed to be working properly. After learning our repeat sample came back at over 3,000 we cleaned the weir that is in-between the sample point and the UV lights. We also disinfected the sump pit that all drainage flows into in the building (it is pumped into the weir after the lights). Update- the butterfly valves for the other u.v bank that was offline were both failing due and raw effluent was getting into the weir, mixing with the disinfected effluent from the bank that has been in operation. Valves have been ordered and both banks are in operation. We have deep cleaned the weir again.
Waterbody Impacted: Otter creek
