But is Glenfaba House being considered again?
Manx Utilities says it's continuing to work with landowners and stakeholders to identify new sites for proposed sewage treatment plants.
It’s purchased a number of sites in the west and east of the Island.
Chair Rob Callister says significant progress has been made.
In 2020 plans for a treatment works at Glenfaba House were opposed – but Mr Callister says the site could still be considered in the future:
