- Secondary Treatment. In secondary treatment, the goal is to break down wastewater even further.
- Tertiary Treatment.

What is the collection system?
“Collection systems” refers to the system of underground pipes and maintenance structures that are used to convey wastewater to a wastewater treatment facility. The use of collection systems has brought dramatic improvements to public health in major cities.
