Improving water quality in Troutbeck

Work has started at Troutbeck wastewater treatment works to install two new Fujiclean units, helping to improve treatment standards at the site.

Over the last two decades, we have invested millions of pounds upgrading our wastewater treatment sites, pumping stations and sewers in and around Windermere. Between now and 2030 we are investing £200 million in the Windermere catchment to further improve treatment standards, reduce phosphorus entering the lake and reduce stormwater spills.

Our project at Troutbeck

We have started on site at our wastewater treatment works in Troutbeck, where we are installing two new Fujiclean units, associated equipment and electrical and mechanical systems required to operate the new process. The Fujiclean units will be underground and there will be some small kiosk buildings visible on site once the project is completed.

Fujiclean is a new innovative, chemical free, sewage treatment which comes from Japan. The compact, modular system treats wastewater effectively using a low amount of energy and are essentially a treatment works in a box, therefore don’t require a large amount of construction or heavy engineering.

There is currently a temporary Fujiclean unit on site which will continue to be in use until the two new units are installed and operational, when it will then be removed.

Why are we doing this

This upgrade to our wastewater treatment works will improve treatment standards at Troutbeck and further reduce phosphorus entering the lake.

What will the impact be locally?

Fujiclean units are easier to install, particularly in locations where roads are narrow and where sites are tight, and therefore minimises the disruption and impact on the local community. 

A temporary access track is being established in an adjacent field so that access to and from the site is not impacting the lane, also making deliveries to site easier. This temporary track will be removed once the project is complete.

During the construction period local residents may notice: 

  • Construction vehicles and delivery wagons travelling to and from the site 
  • Excavators and other construction machinery operating on site 
  • Deliveries of large plant and equipment, including a crane
  • Lifting operations visible from nearby properties 
  • General construction noise, including vehicle movements, reversing alarms and excavation activities 

We appreciate that construction activity can cause some temporary disruption and would like to thank local residents for their patience and understanding while these important environmental improvements are delivered.

When will the project be complete?

The project is due to be completed by Spring 2028, and visualisations of how the site will look in the future can be viewed below.
