Successful replacement of the covers of an existing Rotating Biological Contactor (RBC) at a typical water utility sewage treatment works in England.

The old covers were in a poor state of repair and incorporated a sliding access system which made maintenance difficult. A new and more robust design capable of sustaining a high quality finish and giving easy, safe access with clearance for maintenance within the unit was therefore required. The site levels were also testing as the ground sloped significantly towards the final zone tank.

Jacopa successfully overcame all the challenges and installed new covers based on its own advanced design which incorporated access doors at both ends and base support channels to level the installation. Design, delivery and installation were all accomplished within an exacting time frame including dealing with the site offloading issues often experienced with this kind of project.
