New underground tank proposed for near the Glebe to cut overflows and protect Windermere’s water quality

We’ve announced plans to build a new storage tank at the Glebe as part of our plans to improve water quality in Windermere and it was great to see lots of you at our drop-in sessions to find out more.  

More than 100 of you joined us over two nights at The Belsfield Hotel and Marchesi Centre where we shared our proposals to build a 30-metre diameter, below ground storage tank which can hold around 10,000m3 of stormwater – the equivalent of four Olympic sized swimming pools. 

If you couldn’t make the session, view our plans here.

Subject to securing the necessary planning permission, the tank would help cut the number of times that the storm overflow in the area operates and will help to improve water quality in Windermere.  

Construction would take place on land off Glebe Road and we would work with local stakeholders to minimise disruption to the local community. It is expected that the project would start in 2027 and be completed in early 2030. 

This forms part of our £200 million across the Windermere catchment over the next four years to reduce storm overflow operations and improve the quality of treated wastewater.
