Which source caused the spike?
Chemical oxygen demand load at the Park sewer at CETP inlet reached 120 kg/h on Tue 16:00, against a usual 24 kg/h. Each outlet's load above its own baseline, 2 h earlier (sewer travel time), is ranked below.
- 1. Demo Textiles84 %205 kg above baseline
- 2. Demo Beverages11 %26 kg above baseline
- 3. Demo Steel Works4 %11 kg above baseline
- 4. Demo Battery Recyclers1 %2.1 kg above baseline
- 16 % of the excess could not be traced to a sharing outlet.

| Demo Battery Recyclers | 105 m³/d | 84 mg/L | 9.2 kg/d | 2 % | 1.0 kg/h · Fri 13:00 |
Load = flow × concentration (m³/h × mg/L ÷ 1000 = kg/h). Laboratory results are held for 36 h between samples. Not sharing Chemical oxygen demand data with the park: Demo Foods, Demo Plastics.
Reference case · real public data
Source tracing on a real sewer network
The same question on the real Bellinge network in Denmark (about 1,000 manholes, run in EPA SWMM): how often the engine finds the right manhole, and how much a few well-placed sensors help.
