West Bay CSO 2010 Ns169761
Storm overflow operated by Scottish Water, discharging into Clyde Estuary. CSO.
Right now
"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.
Official figures
2025, from Scottish Water's overflow data reported to SEPA (number of overflow events; Scottish Water does not use the 12/24-hour count). The monitor reported for 85% of the year.
| Year | Events | Hours | Monitored |
|---|---|---|---|
| 2021 | 163 | 422 | — |
| 2022 | 280 | 582 | — |
| 2023 | 360 | 789 | 100% |
| 2024 | 697 | 1,888 | 100% |
| 2025 | 236 | 2,764 | 85% |
"No data" means the monitor was not working or not required to report that year — not zero spills. 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.
Discharges we have observed
937 discharge periods since 1 Jan 2024, 1 still open. 932 of them come from Scottish Water's own event-duration-monitoring records (published by the company, Jan 2024 – Dec 2025); the live feed adds anything after that. The official annual count above is the figure to quote.
Year chips use the EA's 12/24-hour counting method (the first 12 hours of a discharge count as one spill, each further 24-hour block with discharge as one more), so they are comparable with the official figures above; the monitor log's 938 raw blocks were merged into 937 continuous discharge periods (gaps under 15 min joined).
