Concept and detailed design of Woodford Island STP (greenfield SBRs) with John Wilson and Partners (now WhorleyParsons) for Clarence Valley Council (NSW).

Maclean Shire is located on the North Coast of NSW. It consists of a number of small townships, some of which were not sewered. The areas that were sewered were serviced by out of date lagoon treatment systems which were unsuitable for long term sustainability, and were creating increasing odour annoyance for local residence. These systems were replaced by a new reticulation system and a new, high tech sewage treatment facility. The concept involved a new IDEA type nutrient removal facility, with sludge stabilisation, controllable phosphorus removal, wetland polishing and distribution to a number of re-use applications. The aim was to reduce the pollution created through septage leachate, and minimise the nutrient loads discharged to the Maclean River, especially during the more sensitive summer months. The project was delivered in two phases; detailed concept design followed by detailed design and documentation.
