- 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 SBB00517). Rainfall: EA Hydrology gauge 598e7d36-5ea6-4265-9d4b-d65e0e31ac8b. 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.
