Boitnott will be here on Friday September 29, 2017 to collect the sludge from the secondary clarifier. We will go back to normal conditions on Saturday September 30, 2017. Please let me know if you have any questions. TOM ATKINSON
9/14/2017 Atkinson, Tom <[email protected]> 2:29 PM (18 minutes ago) to Dave, Heather, Steven, Sara, John, Kevin All, As we discussed on the phone today: The package plant clarifier effluent will be redirected to discharge directly to the receiving stream and a sump pump will be used to draw the clear liquid off of the secondary clarifier. Caution will be used to ensure that the sump pump does not draw sludge from the secondary clarifier. The total combined discharge from these two clarifiers will be directed through the effluent flow meter and will not exceed 2,000 gpd. It is understood that this combined discharge may last 3-4 days. Once the clear liquid is removed from the secondary clarifier, Boitnott will remove the remaining contents of the secondary clarifier and haul the material to the Ottumwa Water Pollution Control Facility. This will likely occur in two loads, but will be accomplished in one day. Coordination with Boitnott and the City of Ottumwa will be necessary to ensure the availability and capacity to complete the cleaning in one day. Please notify me when the project begins and provide the anticipated schedule for completion. It is expected that the project will completed in one week. One final note I didn't consider during the call; depending on the consistency of the sludge in the secondary clarifier, Boitnott may need liquid in the tank to help break up any compressed solids. I'd suggest contacting them to determine if that will be necessary, and if so, how much liquid is necessary. This determination may limit or even eliminate the use of the sump pump to discharge the clear water from the secondary clarifier. Of course that would increase the volume being hauled, but hopefully could still be accommodated in two loads. If you believe that I misstated what was discussed or if the plans change, please feel free to contact me. Regards, TOM ATKINSON
