Project Overview

Early collaboration allowed for the innovation of the roof and gaseous zones of the Digesters. The Digested Sludge Collection Tank was manufactured in Stainless steel to provide a more resilient tank system.
Roof and top ring installed at ground level avoiding risks working at height.

Innovative solution for the Digested Sludge Collection Tank, with a small diameter where specialist construction methods were required. The tank is now known as the ‘Missile’ tank

Tank package included several full Glass Fused to Steel Tanks.
All design, engineering and installation was carried out inhouse to ensure the highest quality of service to the client and the highest standards when installing on site.

Our package included all the required Access Steelwork as well as Limpet Chambers and Pressure Relief Valves, eliminating traditional interface issues.
Access walkway on the Digester roof installed at low level to reduce working at height issues and improve commercial efficiencies including an expedited programme at the time of install.
