Questions about Louth-Grimsby Rd Cistern SSO

Who operates Louth-Grimsby Rd Cistern SSO?
Anglian Water is the operator named in the annual record. The permit reference is ANNNF13586.
Where does Louth-Grimsby Rd Cistern SSO discharge?
The source names River Lud as the receiving water. This does not show how far a discharge travelled.
How many times did Louth-Grimsby Rd Cistern SSO spill in 2025?
The 2025 return records 3 counted spill events and 15.5 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 Louth-Grimsby Rd Cistern 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 Louth-Grimsby Rd Cistern 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 Louth-Grimsby Rd Cistern SSO compare with other overflows?
Louth-Grimsby Rd Cistern SSO recorded 3 spills in 2025. That is more than 26% of the 14,239 overflows in England with a reported figure, and ranks 9,843rd nationally. Among Anglian Water overflows it ranks 874th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Louth Canal waterbody it ranks 10th of 15. 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.
