Accelerating journey to net zero

Upgrade planning | Project Delivery

After a decade of operation, Wollongong WWTP digester covers were failing. The covers are critical in containing biogas created from the digestion process, which is used for cogeneration, or flared off as needed.

Atlas helped SWC with optioneering and design for replacement digester covers.

Weighing up whole of life cycle costs against various non-cost criteria (safety, risk, sustainability and renewables use), the team recommended an alternative solution – a new “balloon” style cover that increased biogas storage capacity by 300%, leading to a threefold increase in renewable energy use, ROI and creating significant TOTEX savings, while delivering the solution to the anticipated time and budget.

“The best thing was really that the team just pitched in together, to enable the delivery of a really novel, beneficial, and repeatable solutions. Egos and logos were left at the door, and we worked as one team, focused on the best result for the customer”

The installation was first of its type in Australia, reduced safety risk and created a repeatable solution for other SWC plants.
