- Anglian Water is the operator named in the annual record. The permit reference is EPRMB3495AV.

- The source names Inner Harbour (Tidal) as the receiving water. This does not show how far a discharge travelled.
- How many times did St Peter's Street #X Combined Sewer Overflow spill in 2025?
- The 2025 return records 33 counted spill events and 22.3 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is St Peter's Street #X Combined Sewer Overflow 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 St Peter's Street #X Combined Sewer Overflow?
- 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 St Peter's Street #X Combined Sewer Overflow compare with other overflows?
- St Peter's Street #X Combined Sewer Overflow recorded 33 spills in 2025. That is more than 77% of the 14,239 overflows in England with a reported figure, and ranks 3,116th nationally. Among Anglian Water overflows it ranks 127th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Waveney (Ellingham Mill - Burgh St. Peter) waterbody it ranks 3rd of 15. Ranks compare counted spill events only. They do not compare volume or harm.

- 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.
