Sewer Treatment, Storage, and Disposal
The District's original sewer treatment plant was replaced in 2013. The new plant is a MicroBlox Membrane Biological Reactor (MBR) treatment system that includes an additional membrane treatment unit called StormBlox that is only used in the winter when incoming flows exceed the capacity of the MBR unit.
When flows enter the treatment plant headworks from the collection system, it first flows through a drum screen where rags, wipes, and other non-flushable items are collected and disposed of. From the drum screen, the waste flows through two equalization basins before entering the MBR unit. Sludge is wasted from the MBR unit into two dewatering bags, where the sludge is thickened and disposed of at a landfill once dry. The liquid from the bags is captured and sent through the treatment system again.
From the MBR, treated effluent is disinfected and sent from the sewer plant to the pond area for storage and disposal.
