A missing figure means the source did not provide a usable value. A zero is shown as zero. Monitor operation below 90% can make comparison less reliable.

Questions about Snipe Clough CSO
- Who operates Snipe Clough CSO?
- United Utilities is the operator named in the annual record. The permit reference is 016982237.
- Where does Snipe Clough CSO discharge?
- The source names Glodwick Brook as the receiving water. This does not show how far a discharge travelled.
- How many times did Snipe Clough CSO spill in 2025?
- The 2025 return records 20 counted spill events and 93.4 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Snipe Clough 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 Snipe Clough 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 Snipe Clough CSO compare with other overflows?
- Snipe Clough CSO recorded 20 spills in 2025. That is more than 63% of the 14,239 overflows in England with a reported figure, and ranks 5,045th nationally. Among United Utilities overflows it ranks 1,007th of 2,270; the median United Utilities overflow recorded 15 spills. On the Medlock (Source to Lumb Brook) waterbody it ranks 6th of 15. 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.
