Questions about Scrooby Street/CSO
- Who operates Scrooby Street/CSO?
- Yorkshire Water is the operator named in the annual record. The permit reference is C5341.
- Where does Scrooby Street/CSO discharge?
- The source names Greasbrough Dyke as the receiving water. This does not show how far a discharge travelled.
- How many times did Scrooby Street/CSO spill in 2025?
- The 2025 return records 37 counted spill events and 207 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 96.4% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Scrooby 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 Scrooby 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 Scrooby Street/CSO compare with other overflows?
- Scrooby Street/CSO recorded 37 spills in 2025. That is more than 80% of the 14,239 overflows in England with a reported figure, and ranks 2,695th nationally. Among Yorkshire Water overflows it ranks 520th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Greasbrough Dike from Source to River Don waterbody it ranks 3rd of 5. 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.
