During 1970 a pilot-scale water treatment plant was operated at Loch Leven to investigate the feasibility of producing a potable water from such a source.
The study showed that while no particular problems were encountered in producing a water of satisfactory chemical quality it was rarely possible to produce a water of satisfactory biological quality. This was due to the fact that the water treatment processes investigated were unable to retain sufficiently large numbers of the small algae so characteristic of Loch Leven and as a consequence the finished water nearly always contained unacceptably high numbers of algae.
