Cotter Dam Expansion drawing to a close

Actew Water have announced the last roller compacted concrete has been laid on the expanded Cotter Dam.

Canberra’s great wall, the Enlarged Cotter Dam is nearing completion, with the final load of Roller Compacted Concrete (RCC) laid in the early hours of Saturday morning.

This is a significant milestone for the ACT and Queanbeyan community who will benefit from the improved water security the new dam will provide for generations to come.

The wall has all but reached its full height of 80 meters, with the detailed curved concrete cap, which helps control the flow of water over the top of the dam, being the next stage.

Some work remains in 2013 on areas like the concrete structures running down the sides of the dam and in the stilling basin at its base.

The rest of the dam structure and related works will be completed by autumn next year, with the remainder of the rehabilitation, demobilisation and commissioning work due for completion in the winter.

And they’ve even got fun facts for us:

    — 365,000 cubic meters of Roller Compacted Concrete was used to build the bulk of the new dam.

    — 1,000,000 tonnes of rock was used to manufacture the RCC. This was mined and crushed on site, dramatically reducing the associated construction truck traffic and haulage kilometers on the neighbouring roads.

    — The quarry the rock came from will eventually be located under the full supply level of the new dam and will also be used for fish habitat as the new reservoir fills.

and in Qld a bunch of greenies and NIMBYs forced the Beattie government to scrap the proposed Mary River dam.

You didn’t mention all the National voting farmers in your rant.

Thanks for the stats, although you missed a few like completion dates and budget over runs etc.
Noting like grandstanding with only 1/2 the facts. It’s like your media releases are written in a political style.

Give them a break would you.

Quality is remembered long after budgets and schedules are forgotten.

Well done to our friends at ACTEW – thanks to their fairly decisive action we now have a secure water supply in Canberra for generations to come.

Other organisations could learn from ACTEW when it comes to turning major infrastructure from an idea into reality. Could be worse, we could have ended up with study-upon-study-upon-consultation and millions spent with nothing to show for it.

Here’s to engineers and their ability to quietly deliver those things we take for granted everyday!

We shouldn’t forget that this project was proposed during the drought when the greenies were flying high and stopped Labor state governments around the country from building new dams or expanding existing ones. The Brumby government in Victoria shelved plans for a new dam and in Qld a bunch of greenies and NIMBYs forced the Beattie government to scrap the proposed Mary River dam.

In an uncharacteristic display of staring down The Greens and other feral leftists, the Stanhope government bit the bullet and went ahead with the project. I’ll never forget the pride I felt when I read a letter in the Herald Sun from someone who on holiday in the ACT saw ACTEW’s TV ad saying that the Cotter Dam project would secure Canberra’s water supply and asking why the Victorian government could not follow our lead.
