Wallan STP Upgrade

In a joint venture between CCB Envico and Cockram (now ICON), an upgrade to the Wallan Sewerage Treatment was required to cope with the increased development around Wallan in the previous 10 years. This project involved the design, construction, testing, commissioning and proving of an Activated Sludge Plant (ASP) at the Wallan STP. Work included modifications to the existing influent pump station, inlet screen and lagoons, construction of a 4ML/d ASP, design and construction of 6ML/d tertiary filter and associated site infrastructure.
