Water Treatment Works

Rousay WTW, Orkney

Situated 3km the north coast of mainland Orkney, the island Rousay has an indigenous population of around 200. The water supply was identified as part of Scottish Waters SR10 investment programme as requiring upgraded disinfection and cryptosporidium treatment to ensure that it can comply with modern day standards and also to allow for future population growth.

The scope of works included:

  • 6km of new 63mm diam MDPE distribution main from the existing service reservoir to the local school
  • A new cartridge filter building housing pressure accumulator & cartridge filters
  • Associated process chambers, drainage & ducting

The remote location presented challenges, not the least of which was the variable weather conditions which at short notice could disrupt supply arrangements from Mainland across the Eynhallow Sound.

Significant technical input was necessary to integrate the new assets into the existing works – in particular to maximise the output from the existing service reservoir – and this was achieved with the close working relationships which were maintained with Scottish Water’s award-winning Operations team of ‘Rousay Girls’.

Close co-operation and liaison with the local people of Rousay was also essential to ensure minimal disruption to the daily life on the island.
