Questions about Skeffling/STW

Who operates Skeffling/STW?
Yorkshire Water is the operator named in the annual record. The permit reference is WRA8238.
Where does Skeffling/STW discharge?
The source names Tributary of Skeffling Clough Drain as the receiving water. This does not show how far a discharge travelled.
How many times did Skeffling/STW spill in 2025?
The 2025 return records 49 counted spill events and 920 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.
Can I trust the 2025 figures for this outlet?
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 Skeffling/STW 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 Skeffling/STW?
The annual return lists the asset type as “Inlet SO at WwTW”, which means inlet storm overflow at a wastewater treatment works. The overflow is at the inlet of a treatment works, where wastewater enters the works.
How does Skeffling/STW compare with other overflows?
Skeffling/STW recorded 49 spills in 2025. That is more than 87% of the 14,239 overflows in England with a reported figure, and ranks 1,699th nationally. Among Yorkshire Water overflows it ranks 313th of 2,176; the median Yorkshire Water overflow recorded 16 spills. Ranks compare counted spill events only. They do not compare volume or harm.
Does zero spills mean the water was safe?
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.
