Algorithm 5. Agglomeration: Article 4, 5, 6 Compliance Exclusion#

Overview#

Filters agglomerations based on connected plants and their treatment compliance, setting Art. 4–6 compliance accordingly, and delegates further processing to Algorithm 6 if conditions are not conclusive.

It also calls Algorithm 10 and Algorithm 11 when all plants are NR/NI with required “Appropriate treatment”.

Simplified Logic#

Some wastewater collected#

(sum_percent_wastewater_collected > 0)

1. Checks if plants are connected#

2a. At least one plant connected#

Checks if all connected plants require Appropriate treatment and have compliance = NR or NI:
- If yes:
  - Art. 4, 5, 6 compliance = NR
  - Calls Algorithm 10 and Algorithm 11 for additional processing
- If not:
  - Checks if at least one plant has compliance = “?” and the rest are C/NR/PD:
    - If yes →
      - Art. 4, 5, 6 compliance = “?” (unknown)
      - exit_leaf = 05-02
    - Otherwise →
      - Calls Algorithm 6 to continue processing

2b. No plants connected#

Two sub-cases based on aggGenerated:
- aggGenerated > 10000 →
  - Art. 4 & 5 = “?”
  - Art. 6 = NR
  - exit_leaf = 05-01
- aggGenerated < 10000 →
  - Art. 4 = “?”
  - Art. 5 & 6 = NR
  - exit_leaf = 05-03
