Questions about Masbrough Street/CSO

Who operates Masbrough Street/CSO?
Yorkshire Water is the operator named in the annual record. The permit reference is 3375.
Where does Masbrough Street/CSO discharge?
The source names Holmes Tail Goit as the receiving water. This does not show how far a discharge travelled.
How many times did Masbrough Street/CSO spill in 2025?
The 2025 return records 36 counted spill events and 90.5 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 80.6% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
Is Masbrough Street/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 Masbrough Street/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 Masbrough Street/CSO compare with other overflows?
Masbrough Street/CSO recorded 36 spills in 2025. That is more than 79% of the 14,239 overflows in England with a reported figure, and ranks 2,801st nationally. Among Yorkshire Water overflows it ranks 543rd of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Don from Greasborough Dyke to River Dearne waterbody it ranks 9th of 37. 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.
