Sign in to saveStorm overflow run by Scottish Water, discharging into Black Cart Water.
"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 23 September (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.
Twin outlet
Scottish Water runs another overflow within 300 m that also discharges into Black Cart Water. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.
Discharges we have recorded
13 discharge periods since 17 Sep 2026. Recorded from the live status feed only — Scottish Water has not published an event-level log we hold, so this is what the feed has shown us, not a complete record. 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 14 raw blocks were merged into 13 continuous discharge periods (gaps under 15 min joined).
Look back by date
Discharge records held: 1 Jul 2022 to 31 Dec 2025 and from 24 Sep 2026. Choose the dates of a flood or a storm to see every discharge recorded then.
Days run midnight to midnight, UK time, up to 366 days at a time. A discharge beside rain or a flood is a timing match, not proof of cause, and no volume is published.
What the feed showed
FloodRadar's own record of every change of state Scottish Water's live feed has shown for this overflow, kept since : 9 states. The feed publishes its status now and its latest discharge, nothing older; the discharges above are read from this. It is here so the figures can be checked.

Rain nearby last 30 days
Nearest live rain gauge: Lochwinnoch, 8.9 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).
Where it is
Tell me when this overflow discharges
One message when the company's monitor reports a new discharge here. At most one every 6 hours.
Setting this alert needs JavaScript. The alerts you already have are on your alerts page.
The alert repeats the monitor's status: whether the overflow is discharging, not how much or why. It can only tell you about a discharge that starts after you turn it on.
Concerned about this overflow?
Report pollution you can see or smell to the regulator straight away; the company handles complaints about the overflow itself.
