Perth City WwTW - Post-pst Ssso
Storm overflow operated by Scottish Water, discharging into River Tay. SSSO.
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 83% of the year.
| Year | Events | Hours | Monitored |
|---|---|---|---|
| 2021 | 72 | 3,317 | — |
| 2022 | no data | — | |
| 2023 | 114 | 4,347 | 100% |
| 2024 | 168 | 5,832 | 98% |
| 2025 | 234 | 1,754 | 83% |
"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
407 discharge periods since 1 Jan 2024, 1 still open. 402 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 415 raw blocks were merged into 407 continuous discharge periods (gaps under 15 min joined).

Rain nearby — last 30 days
Nearest live rain gauge: Perth Norwich Union, 5.1 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).
