Collapse of the Bridgewater Canal
Guidance and advice following the collapse of the Bridgewater Canal in Little Bollington.
What happened at the canal
Significant rainfall resulted in flooding and the collapse of the Bridgewater Canal in Little Bollington, near Dunham Massey, on New Year’s Day 2025.
The flooding was classified as a major incident, with a multi-agency response by local partners.
Emergency stoplogs – which are designed to cut off or stop the flow of water –were installed at Adgen and Dunham by the Bridgewater Canal Company, which is part of the Peel Group, to isolate the affected section. This led to around 1.9 miles (3kms) of the canal being drained of water.
This action also prevented a full loss of the canal and helped to stop further flooding which had been caused by extreme weather leading up to the incident.
The current situation
As a result of the incident on New Year’s Day, flood water and sediment from the canal spilled over into neighbouring farmland, and the site and surrounding public rights of way were closed off by the council due to possible contamination and the protection of the public.
Testing has now confirmed that flood-affected soils at the site do not pose a risk to people using the site or to the environment. It has also been confirmed there is no threat of pollution to nearby surface waters, including the River Bollin, or to groundwater.
If flood-affected soils are required to be disposed of, the tested material is classified as non-hazardous.
Following the results of the testing, which have been endorsed by multi-agency partners, the council is now able to reopen the public rights of way that were impacted by the incident.
The area directly surrounding the canal breach, including the canal towpath between Woodhouse and Little Bollington underbridges, remains closed to the public.
Since the breach at Little Bollington, the Bridgewater Canal Company team has been working to protect the canal and surrounding infrastructure.
The current aim is to have the canal fully reopened to navigation – including the Cheshire Ring – by December 2026.
For questions or more information about reopening the canal, visit the Bridgewater Canal website or email the Bridgewater Canal at Peel.
Safety of the public
Signage is in place to advise the public of the remaining closures as outlined above and we recommend people keep clear of these sections.

United Utilities
The incident damaged part of the public sewer that discharges into Dunham Massey wastewater treatment works.
Currently, the part of the sewer network that transports wastewater from Little Bollington to Dunham Massey wastewater treatment works is damaged and not useable.
To maintain service to residents of Little Bollington, United Utilities have put in place alternative arrangements to transport wastewater to the treatment works via tankers. The Wastewater Treatment Works continues to operate as normal.
You may see tankers in the local area around Park Lane and Park View, helping United Utilities to transport wastewater to the works.
Unfortunately, due to the complex repairs that need to happen, a definitive timeline cannot be given of when these works will be completed or when flow into the treatment works can be restored from this part of the sewer network.
United Utilities continues to look at options to minimise disruption and put the sewer back into operation and would like to thank residents for their patience throughout this incident.
Contact United Utilities.
