Questions about Twywell Sp
- Who operates Twywell Sp?
- Anglian Water is the operator named in the annual record. The permit reference is AW5NF681.
- Where does Twywell Sp discharge?
- The source names A tributary of the Alledge Brook as the receiving water. This does not show how far a discharge travelled.
- How many times did Twywell Sp spill in 2025?
- The 2025 return records 13 counted spill events and 64.3 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 Twywell Sp discharging right now?
- This record is not matched to a company live feed, so we cannot show a current report. Only the annual figures are available for this outlet.
- 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 Twywell 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 Twywell Sp compare with other overflows?
- Twywell Sp recorded 13 spills in 2025. That is more than 53% of the 14,239 overflows in England with a reported figure, and ranks 6,413th nationally. Among Anglian Water overflows it ranks 412th of 1,438; the median Anglian Water overflow recorded 6 spills. Ranks compare counted spill events only. They do not compare volume or harm.
- Does zero spills mean the water was safe?
