How many times did Dyke Vale Road 1/CSO spill in 2025?
The 2025 return records 27 counted spill events and 46.3 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 92.8% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Dyke Vale Road 1/CSO 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 Dyke Vale Road 1/CSO?
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.
