Questions about Earls Barton Blackwell Cl SSO
- Who operates Earls Barton Blackwell Cl SSO?
- Anglian Water is the operator named in the annual record. The permit reference is AW5NF2031.
- Where does Earls Barton Blackwell Cl SSO discharge?
- The source names Trib River Nene as the receiving water. This does not show how far a discharge travelled.
- How many times did Earls Barton Blackwell Cl SSO spill in 2025?
- The 2025 return records 0 counted spill events and 0 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

- The monitor worked for 54.5% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Earls Barton Blackwell Cl SSO 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 Earls Barton Blackwell Cl SSO?
- 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 Earls Barton Blackwell Cl SSO compare with other overflows?
- Earls Barton Blackwell Cl SSO recorded no spills in 2025. It is one of 2,231 overflows in England with a reported count of zero, out of 14,239 with a count. 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.
