Works to progress critical capital programme of works at Drogheda Wastewater Treatment Plant

24 February 2023

Uisce Éireann is continually investing in water and wastewater services in Drogheda and is currently delivering an extensive programme of works at the Drogheda Wastewater Treatment Plant and on the network.

A significant amount of work has already been completed including works to the odour control units, the three primary settlement tanks and two aeration tanks. In addition, odour neutralising treatment has been installed at the East Meath and Bryanstown pumping stations to help reduce the potential for odours arising in the network as the wastewater travels to the treatment plant. Seasonal odour neutralising treatment will continue to be applied at the East Meath Pumping station over the 2023 summer season.

The next phase of the capital programme involves works on the anaerobic digesters. As a priority, the replacement of the No. 1 anaerobic digester is advancing on site and construction is estimated to be completed in Q3 2023.  

At several locations throughout the network sealed manhole covers will be introduced to help prevent the release of any odours.

On an ongoing basis network jetting is being undertaken in Drogheda to release general blockages in the network.

Redmond Burke, Wastewater Engineer at Uisce Éireann, said: “Carrying out works to Drogheda’s wastewater infrastructure and reducing any potential for odours to arise from the treatment plant or sewer network remains an absolute priority for us.  The ongoing works represent a significant investment by Uisce Éireann and we will continue to provide frequent updates until the project has been completed.

We will continue to review operational data from the treatment plant to evaluate any appropriate additional measures for the site.

Separately, Uisce Éireann advises that essential maintenance works will take place at the treatment plant on Monday 27 February. During these works, there is a risk of intermittent odours from the plant, however, Uisce Éireann will make every effort to minimise the risk of odours and to complete these works as quickly as possible.

If odour issues are noted, please contact the Uisce Éireann  Customer Care Centre helpline, open 24/7, on 1800 278 278 or email Real time reporting allows for the investigation of the reported odour as close to the time of the incident as possible. Uisce Éireann would like to apologise for any odours that arise while these essential maintenance works are being carried out.
