Deficiencies
Anoxic MixersCurrently a Medora mixer in place to keep Anoxic tank solids moving. May need to consider this in future updates.
Sand Filter RebuildSand Filters have never been rebuilt or media replaced. Should price and schedule for the near future.
Train Down for ReviewOne process train is down for review of deficiencies.
Pump StationPump Station pumps clogging issues have been an issue for some time. Pump Station mixing should be implemented to help with pump failure and pump station pump outs.Pump Station pumps clogging issues have been an issue for some time.
