Questions about Manchester Road/Dalesford Road

Who operates Manchester Road/Dalesford Road?
United Utilities is the operator named in the annual record. The permit reference is 01ROS0011.
Where does Manchester Road/Dalesford Road discharge?
The source names Rvr Irwell via Langwood Brook as the receiving water. This does not show how far a discharge travelled.
How many times did Manchester Road/Dalesford Road spill in 2025?
The 2025 return records 58 counted spill events and 52.9 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 99.4% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Manchester Road/Dalesford Road 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 Manchester Road/Dalesford Road?
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 Manchester Road/Dalesford Road compare with other overflows?
Manchester Road/Dalesford Road recorded 58 spills in 2025. That is more than 91% of the 14,239 overflows in England with a reported figure, and ranks 1,191st nationally. Among United Utilities overflows it ranks 333rd of 2,270; the median United Utilities overflow recorded 15 spills. On the Irwell (Cowpe Bk to Rossendale STW) waterbody it ranks 3rd of 9. 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.
