GMW delivers more maintenance than ever before

Monday 16 January, 2017

For Goulburn-Murray Water (GMW) the past works year has been about delivering.

During 2016, the water corporation not only delivered major projects under time and budget, it completed more maintenance than ever before.

GMW’s Customer Infrastructure and Assets Team completed about 400 capital works projects within budget at a cost of $35.7 million while the Connections Project carried out its $45 million Winter Works program.

It also delivered about $30 million of maintenance works, which includes more channel desilting than ever before.

“All of these works are about efficiently improving services to our customers,” GMW General Manager of Customer Operations Scott Barber said.

“Major dam projects ensure the long term security of water supply for our customers, while desilting works improve or restore flow rates to irrigators.

“I think our business can be rightly proud of the achievements it’s made this year, but it certainly puts the challenge out there for next year.

“In 2016/17 we already have another $40 million of works to complete including upgrade or replacement of 40 structures, about 35km of channel remodelling to do and ongoing system maintenance to deliver required customer service levels.”

GMW’s works year runs from July 1 to June 30.
