Recent Job – Arddleen
The team recently worked at Arddleen Sewage Treatment Works to refurbish the existing reed bed.
The refurbishment involved civil works including temporary treatment and over-pumping arrangements, removing and replacing the existing reed bed materials, and carrying out the associated concrete works, earthworks and general civils and installing and commissioning a new aeration system.
The site itself presented a few challenges, with narrow access, working around an operational treatment works, and the potential for flooding, so careful planning and coordination were key throughout the project
The works also involved managing waste removal and disposal, protecting the existing access route and surrounding ground, and working around the site’s ongoing operations.
A great example of a project balancing refurbishing an existing asset and keeping the site operational throughout
