Components of the System

• Septic Tanks
• Future Optional Vertical Flow Reed Bed to Treat Septage
• Sub-Surface Flow Constructed Wetlands
• Sizing of Wetlands for Sewage Treatment Following Pre-Treatment in Septic Tanks

I am not sure if this is the appropriate title for the subsection. Can you write a short introduction for this subsection?

I think this subsection in all its parts (septic tanks, Vertical Flow Reed Bed, SSFCW, etc.) needs more images too.
