Questions about East Maintenance
- Who operates East Maintenance?
- Anglian Water is the operator named in the annual record. The permit reference is ASETS12156.
- Where does East Maintenance discharge?
- The source names River Orwell as the receiving water. This does not show how far a discharge travelled.
- How many times did East Maintenance spill in 2025?
- The 2025 return records 35 counted spill events and 7 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 East Maintenance 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 East Maintenance?
- 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 East Maintenance compare with other overflows?
- East Maintenance recorded 35 spills in 2025. That is more than 78% of the 14,239 overflows in England with a reported figure, and ranks 2,896th nationally. Among Anglian Water overflows it ranks 116th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Orwell waterbody it ranks 4th 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.
