What Council's Doing

Photos of Construction of Water Filtration Plant

Work began in October 2007 on the construction of the new Coffs Harbour Water Filtration Plant at Karangi.

The $59 million Water Filtration Plant project is one of three major projects being implemented through the Coffs Infrastructure Alliance. The project is expected to be completed in early 2009.

Photos showing the progress of construction:

Preparations for WTP foundations   WTP site western view to east

Coffs Infrastructure Alliance team members with Chairman of Council's City Services Committee, Councillor Bill Palmer, after inspecting the Water Filtration Plant's Dissolved Air Filtration and Flotation (DAFF) building site. Concrete has now been poured to provide a blinding layer that will assist in constructing foundations (photo Nov 28, 2007). 

 

The view east towards the site of the new Water Filtration Plant's main building. Earthworks continue, and temporary buildings have been erected to service the needs of about 80 workers who will be on the site during peak construction periods (photo Nov 28, 2007). 

WTP site for holding tanks   WTP sediment pond construction

Local media were at a site inspection of earthworks in preparation for construction of the new Water Filtration Plant. A total of 22,000 cubic metres of earth was removed from various construction sites, 8,000 cubic metres of high quality fill was restored, and 5,000 cubic metres of fill is being recycled to build the Bakers Road storage facility, a flood mitigation project (photo Nov 28, 2007). 

 

Construction works to build a 2 megalitre sediment pond as part of the Water Filtration Plant project. An additional pond is being created to act as an emergency storage facility (photo Nov 28, 2007). 

DAFF excavations
