Daldowie WWTW is one of four sewage treatment works that serve the Greater Glasgow catchment.

In order to address issues of quality, asset deterioration and population growth, process improvements were required to be made to the existing plant.


Briefly, the work will involve replacement of the existing inlet screens to include new CSO (6DWF) screens, new coarse and fine screens and installation of FBDA aeration within existing aeration lanes to replace the existing surface aerators.

The existing detritors will also be refurbished (by others and not part of this project) and once refurbished their control shall be incorporated into a new inlet MCC as part of this project.

The existing Phase 1 and Phase 2 MCCs, currently feeding the surface aerators, will be retained and upgraded as they will still be required to supply and control other areas of the plant.
