- Yes — the treatment works' own overflow stayed shut that day, so capacity was available. Avoidable.
Method & provenance. Dry/wet classification is decided by rainfall at the nearest EA gauge — ≤ 0.25 mm on the spill day and each preceding day of the window (how we classify). Spill data: Environment Agency EDM (outlet SBB00913). Rainfall: EA Hydrology gauge 323b21d8-c9a4-4681-bc5c-62d7337993ac. A dry spill is precautionary evidence of a likely fault, not proof of an offence — we test the rainfall, not the works' flow. Generated by River Teign Data.
