The NPS Batch-Treat CA Series Systems have five biological treatment zones:

• Solids Retention Zone (A)  to hold sewage until it is broken down for treatment.
• Aeration Zone (B) to supply oxygen to the aerobic organisms. 
• Settling Clarifier (C) where suspended solids settle out of the final effluent.
• Effluent Discharge Zone (D) that is pumped to the disposal field after the settling period.
• The Reserve Volume Zone (E) which acts as a buffer to absorb large inflows of sewage without affecting the Batch-Treat process.
