ABSTRACT

In June 2007 Bricon was one of three firms selected from an Expressions of Interest process to provide a tender for the design and construction of an ozonation plant to be located alongside Armidale’s existing Water Treatment Plant. The tender was issued in August 2007 and closed on the 9th October 2007. The letter of acceptance was issued to Bricon at the end of November
2007. The value of the tender was $3.45 million.

Design work commenced immediately and preliminary design drawings were provided in January 2008. CHAIR (construction related) and HAZOP (operational review) meetings were held and a final design provided for Council’s approval in March 2008. Construction commenced in April 2008 with site clearance and excavation and the new facility was essentially complete in December. Unfortunately problems with equipment from Wedeco, who provided the ozone generators, injectors and destructor, delayed completion of
commissioning until February 2009.

During the whole of this process the contractor’s local knowledge together with continuing feedback from plant operators and Council’s engineers and supervisors led to a number of changes that made the completed facility easier and more pleasant to operate.
