Questions about Back Heights/CSO

Who operates Back Heights/CSO?
Yorkshire Water is the operator named in the annual record. The permit reference is 1125.
Where does Back Heights/CSO discharge?
The source names Pitty Beck (via SW Sewer) as the receiving water. This does not show how far a discharge travelled.
How many times did Back Heights/CSO spill in 2025?
The 2025 return records 1 counted spill events and 0.3 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 Back Heights/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 Back Heights/CSO?
The annual return lists the asset type as “Storm discharge at pumping station”, which means storm discharge at a pumping station. The overflow is at a pumping station that moves sewage through the network.
How does Back Heights/CSO compare with other overflows?
Back Heights/CSO recorded 1 spill in 2025. That is more than 15% of the 14,239 overflows in England with a reported figure, and ranks 11,130th nationally. Among Yorkshire Water overflows it ranks 1,777th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Clayton Beck (Source to Bradford Bk) waterbody it ranks 11th of 17. 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.
