Questions about Kings Lynn-Nar Lane Sp
- Who operates Kings Lynn-Nar Lane Sp?
- Anglian Water is the operator named in the annual record. The permit reference is AECTS10364.
- Where does Kings Lynn-Nar Lane Sp discharge?
- The source names Tidal River Great Ouse as the receiving water. This does not show how far a discharge travelled.
- How many times did Kings Lynn-Nar Lane Sp spill in 2025?
- The 2025 return records 75 counted spill events and 178 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 Kings Lynn-Nar Lane Sp 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 Kings Lynn-Nar Lane Sp?
- 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 Kings Lynn-Nar Lane Sp compare with other overflows?
- Kings Lynn-Nar Lane Sp recorded 75 spills in 2025. That is more than 95% of the 14,239 overflows in England with a reported figure, and ranks 620th nationally. Among Anglian Water overflows it ranks 19th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Great Ouse waterbody it ranks 1st of 11. 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.
