A new treatment plant and grease trap has been approved with conditions for the Lingholm estate on the western shore of Derwentwater.
Lake District National Park Authority planning documents said the plant would be underground on a grassed area approximately 115 metres north west of an approved holiday apartment and next to the existing treatment plant which is to be retained to act as pre-treatment for the proposed plant.
The papers say that the plant is needed to avoid an adverse effect on the integrity of the River Derwent and Bassenthwaite Special Area of Conservation (SAC) in accordance with the local plan.
Above Derwent Parish Council supported the application as it would be an environmental improvement.
Permission has been granted for the conversion of a staff and prep room on the site to create a new one-bedroom holiday apartment which would result in an increase of overnight accommodation on the Lingholm Estate and therefore an increase of phosphate being released into the SAC.
The existing treatment plant does not reduce the output of phosphate in any meaningful way,’ say planning documents.
The replacement foul drainage plant will also serve the café and would remove 80.2 per cent of the phosphates from the waste water.
