"Not discharging" means the company's monitor reports no discharge right now — not that the water is clean. The feed publishes status only; no discharge volume is measured.

Year by year

Scottish Water's published data for monitored overflows (number of overflow events; Scottish Water does not use the 12/24-hour count). 2026 is our own running count, the same way, from the live feed since 28 February (when we began keeping every discharge it reports) — so it can only be lower than the full year. The official figure is published next spring.

"No data" means the monitor was not working or not required to report that year — not zero. Scottish Water counts each overflow event; England and Wales count 12/24-hour "spills", so these numbers are not directly comparable with English or Welsh overflows.

Twin outlet

Scottish Water runs another overflow within 300 m that also discharges into River Tweed. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.

Discharges we have recorded

1,320 discharge periods since 1 Jan 2025. 1,290 of them come from Scottish Water's own event-duration-monitoring records (published by the company, Jan 2025 – Dec 2025); the live feed adds anything after that. The official annual count is the figure to quote.

The year figures above use the EA's 12/24-hour counting method, so they are comparable with the official figures; the monitor log's 2,441 raw blocks were merged into 1,320 continuous discharge periods (gaps under 15 min joined).

Nearest live rain gauge: Ormiston Mill, 10.0 km away. Brown shading = when this overflow was discharging; ▼ = a discharge start.

Overflow shading is a timing match, not proof of cause — heavy rain and spills share a trigger. Times come from the water company’s event-duration monitor (site status only; no discharge volume is published).
