Which source caused the spike?
Chemical oxygen demand load at the Park sewer at CETP inlet reached 134 kg/h on Thu 15:00, 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 Textiles86 %237 kg above baseline
- 2. Demo Beverages11 %29 kg above baseline
- 3. Demo Steel Works3 %7.5 kg above baseline
- 4. Demo Battery Recyclers0 %1.1 kg above baseline
- 15 % of the excess could not be traced to a sharing outlet.

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.
