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 Deanscales PS and CSO
- Who operates Deanscales PS and CSO?
- United Utilities is the operator named in the annual record. The permit reference is 017570034.
- Where does Deanscales PS and CSO discharge?
- The source names Tributary of Far Stock Beck as the receiving water. This does not show how far a discharge travelled.
- How many times did Deanscales PS and CSO spill in 2025?
- The 2025 return records 77 counted spill events and 516.5 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 99.6% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Deanscales PS and 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 Deanscales PS and 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 Deanscales PS and CSO compare with other overflows?
- Deanscales PS and CSO recorded 77 spills in 2025. That is more than 95% of the 14,239 overflows in England with a reported figure, and ranks 565th nationally. Among United Utilities overflows it ranks 170th of 2,270; the median United Utilities overflow recorded 15 spills. On the Marron waterbody it ranks 3rd of 8. 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.
