The water company is continuing to make good progress on the upgrade and improvement projects in knustford which, on completion will provide additional storm water storage. Reduce storm overflow operations and improve the quality of treated water we return to the environment.   

The improvements work form part of the broader Big North West upgrade which will see over £13 billion invested in thousands of projects over the next 4 years. 

Part of the project involves the construction of a massive 1.8km long and 2 meter diameter underground storage tunnel. 

The tunnel will hold storm water during periods of heavy rain and runs between Moor Pumping Station and Knutsford Treatment works. When conditions allow, the stored water will be released from storage and treated as normal.  

Tunnel boring machine Lily was tunnelling almost 20m below ground at the deepest point. The TBM’s re-emergence signals the halfway point of the project which is on schedule to store up to 5.5 million litres of stormwater - on completion, United Utilities said Moor Pool will be example of lasting environmental resilience.
