Questions about Boston Sleaford Road Pumping Station
- Who operates Boston Sleaford Road Pumping Station?
- Anglian Water is the operator named in the annual record. The permit reference is ANNNF13727.
- Where does Boston Sleaford Road Pumping Station discharge?
- The source names North Forty Foot Drain as the receiving water. This does not show how far a discharge travelled.
- How many times did Boston Sleaford Road Pumping Station spill in 2025?
- The 2025 return records 9 counted spill events and 6.9 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 Boston Sleaford Road Pumping Station 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 Boston Sleaford Road Pumping Station?
- 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 Boston Sleaford Road Pumping Station compare with other overflows?
- Boston Sleaford Road Pumping Station recorded 9 spills in 2025. That is more than 45% of the 14,239 overflows in England with a reported figure, and ranks 7,492nd nationally. Among Anglian Water overflows it ranks 543rd of 1,438; the median Anglian Water overflow recorded 6 spills. On the Black Sluice IDB draining to the South Forty Foot Drain waterbody it ranks 8th 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.
