During the project – which is due to start in November – the water firm will lay a new 6.5km sewer and upgrade two local wastewater treatment works. It hopes this will significantly reduce the amount of phosphorus in the lake.
Phosphorous can cause algal blooms, which reduce the amount of oxygen in the water – inhibiting aquatic life, and potentially impacting on recreational uses of the lake.
The scheme will reduce the number of times the sewer network overflows into the lake during heavy storms. These overflows are a contributor of phosphorous in the lake.
Work will include the creation of a new 6.5km sewer to take extra sewage flows to the company’s Windermere wastewater treatment works.
UU will also carry out improvement work at its existing Glebe Road pumping station and upgrades at both Windermere and Ambleside wastewater treatment works.
Work will take place throughout the winter months until March 2017. Successive winter periods of work in 2018 and 2019 will also be required, with completion of all projects expected by March 2020.
