Questions about Wheatley/No 2 CSO

Who operates Wheatley/No 2 CSO?
Yorkshire Water is the operator named in the annual record. The permit reference is NPSWQD008129.
Where does Wheatley/No 2 CSO discharge?
The source names An Unnamed Tributary Shef & Sy Navi as the receiving water. This does not show how far a discharge travelled.
How many times did Wheatley/No 2 CSO spill in 2025?
The 2025 return records 9 counted spill events and 44 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 93.3% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Wheatley/No 2 CSO 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 Wheatley/No 2 CSO?
The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
How does Wheatley/No 2 CSO compare with other overflows?
Wheatley/No 2 CSO recorded 9 spills in 2025. That is more than 45% of the 14,239 overflows in England with a reported figure, and ranks 7,492nd nationally. Among Yorkshire Water overflows it ranks 1,317th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Hatfield Waste Drain Catchment (trib of Torne/Three Rivers) waterbody it ranks 6th of 11. 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.
