Water is once again running through a Victorian pipeline, marking the end of a major repair programme.
The pipeline pumps water from the Lake District to Manchester
The 100-mile long Thirlmere Aqueduct, which carries water from Cumbria to the Manchester area, was built in 1885.
During the £750,000 project, engineers re-lined three of the sections with a special waterproof plastic.
While that was being carried out, an inspection team also went through some of the tunnel sections checking where work needed to be done in the future.
Due to the remote location of the stretch between Thirlmere and Kendal, workers and their equipment had to be transported by helicopter.
The aqueduct was out of service for the duration of the work, with supplies for Manchester pumped down from Haweswater and Windermere.
