How many times did HORTON-IN-RIBBLESDALE WwTW spill in 2025?
The 2025 return records 35 counted spill events and 433.4 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

The monitor worked for 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is HORTON-IN-RIBBLESDALE WwTW discharging right now?
This record is linked to a company live feed. The panel above shows the latest report we hold, with its date. That report can be old, and the monitor can be offline, so check the date before relying on it. A report that no discharge is taking place is not a water-quality result.
How accurate is the map marker?
The marker comes from the grid reference in the official annual return, which is accurate to about 1 metres. It shows the recorded outlet position, not the extent of any discharge.
What kind of outlet is HORTON-IN-RIBBLESDALE WwTW?

Among United Utilities overflows it ranks 667th of 2,270; the median United Utilities overflow recorded 15 spills. Ranks compare counted spill events only. They do not compare volume or harm.

No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
