Description of Treatment Plant

Class III, 1.5 MGD plant consisting of a lift station followed by a bar screen and grinder, primary sedimentation using clarifiers and biological treatment using oxidation ditches and secondary clarification.  The final effluent is chlorinated and dechlorinated and the flow is measured.  Sludge is thickened using gravity thickeners prior to anaerobic digestion.  The sludge is then hauled to the Indianapolis Belmont WWTP.  The final effluent is discharged to White Lick Creek.

Design Flow 1.5 MGD
Peak Flow     2.5 MGD
Design pop.   10,000
Design Removal 95% BOD, SS & Ammonia Nitg.
Plant Effluent Limitations 25 mg/1 CBOD, 30 mg/1SS, 1.5 mg/1 Ammonia Nitg.
Avg. Daily Flow 1.485 MGD

The plant is at 99% capacity.  At this time we are upgrading our bar screen to a mechanical fine screen and installing a grit screw system.  Also, we are installing a new sludge thickening process using Rotary Drum Thickeners.  In the near future we will need a plant expansion to raise our capacity because of the Town’s growth.
