Mauchline WwTW-New Storm Tanks 6dwf Ssso
Storm overflow run by Scottish Water, discharging into River Ayr.
"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 overflow data reported to SEPA (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.
Other outlets here
Scottish Water runs 2 other overflows within 300 m that also discharge into River Ayr. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.
This overflow: 41 spills in 2025. Distances are between the published outlet points.
Discharges we have recorded
76 discharge periods since 21 Jan 2024. 74 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 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.
Rain nearby last 30 days
Nearest live rain gauge: Blackdyke Farm, 5.2 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).
