Ganol Wastewater Treatment Project

Civil Engineering Shortlisted schemes

Aim of the complex Ganol Wastewater Treatment Project was to achieve Blue Flag bathing water quality at three important beaches in the holiday area around Llandudno and Colwyn Bay in just 18 months. And at a cost of £45M, the project lays claim to be the largest environmental improvement ever undertaken in North Wales.

Work was bid on outline designs and successful contractors were brought into the detailed design process so that the final methods chosen would make the best use of their individual expertise.

Many new pumping stations and sewers were required to upgrade the network, add storm storage, transfer flows to a new 'odourless' treatment works at Ganol and dispose of effluent through new pumping mains and a long sea outfall.
