The monitor worked for 92.5% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Tonge Bridge Way combined sewer overflow 078NN 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 Tonge Bridge Way combined sewer overflow 078NN?
