Notes and Descriptions

Black vertical lines - the generalized representation of supporting structure
Red Stripes - Catwalks (access)


Piping has been omitted but the flow sequence is as follows (click here for description):
grit chamber  -  primary clarifier  -  anaerobic - anoxic - aeration - final clarifier - gravel pit - chlorination

- All containers with the exception of the gas container will be filled with sewage.
- Sludge from the primary and final clarifiers go to the dewatering station and then to the digester and gas from the digester and the anaerobic go to the gas container.
- The pump house, dewatering facility and the grit chamber are all sitting on the gravel pit (ground).
- The approximate height of the entire structure will be 220 feet with a diameter of 110 feet.
- The total weight of the water/sewage is 12,000 tons.

Early Draft
which includes piping (but no primary clarifier)

This is a graphic representation of an early vision of our product.  Perhaps the most notable change has been the elimination of concrete walls.  This greatly decreases construction costs.    Another change made since this diagram was originally drawn was the removal of the overflow reservoir.  Since a decision whether or not to include a reservoir in the treatment solution would vary on a city by city basis depending on climate, topography, quality of existing storm drain system, and the population flux.
