An iconic Greater Western Water (GWW) tower is being used to celebrate the movement of water as part of a colourful lighting installation in Tarneit.
GWW’s Cowie’s Hill Water Tower will project moving, colourful designs throughout the year that explore the movement of water and function of the water tower.
The lighting installation was funded through the State Government’s Suburban Revitalisation Program and was recently launched by the Member for Tarneit Sarah Connolly and Wyndham City Mayor Cr Peter Maynard.
GWW is delighted to have worked with Wyndham City Council, in partnership with the Tarneit Revitalisation Board, Melbourne Water and the Tarneit Revitalisation Program - which aims to create vibrant and active spaces for community to enjoy - to help bring this project to life.
The Cowie’s Hill Water Tower is owned and operated by GWW and sits on a hill on the corner of Annaliese Street and Pauline Way in Tarneit.
