Coliban Water wishes all our customers a happy and safe festive season.

We thought you might like to see some beautiful aerial photographs of our three major catchment storages near Kyneton: Malmsbury, Lauriston and Upper Coliban.

The photos were taken in December by our Board Director, Noel Harvey.

Our Catchment Storages on 23 December 2011 are at 95.6% (66,522 megalitres). For more information and to visit our Reservoir Levels page > click here

Birdlife at the Bendigo Water Reclamation Plant is booming.

The plant treats wastewater for Coliban Water’s 88,000 customers in Bendigo and includes the Bendigo Water Factory, which produces recycled water for use on public gardens, sporting facilities and irrigation in the Bendigo area.

The site’s 67 hectares of lagoons and treatment ponds makes excellent habitat for wildlife and attracts thousands of birds, with 112 species recorded at the site including threatened species such as the Freckled Duck, Blue-billed Duck and the Australasian Shoveler.

The plant is part of the ‘Land for Wildlife’ program, run by the Department of Sustainability and Environment to encourage landholders to provide habitat for wildlife even though the property may be managed for other purposes.

Land for Wildlife has been in operation since 1981. There are now more than 5,900 Victorian Land for Wildlife properties managing over 560,000 hectares as wildlife habitat.

For the past year the birds at the Bendigo plant have been monitored by bird watching enthusiast and photographer Ian Mayo.

Ian visits the plant on a monthly basis and has been able to record a pattern of the birdlife that passes through, visits for food or makes the site its home.

He spots around 35 species of birds on every visit and in his most recent visit with three other birders they spotted 62 species. 

Ian says that every time he visits the plant he sees something new.

“You see the full cycle of life. One time I witnessed a mass hatching of dragonflies, popping out of their cocoons, drying their wings and flying off. Suddenly a family of Rainbow Bee-eaters came swooping down and snapped up the dragonflies,” says Ian.

“I’m a fan of the raptors – Swamp Harriers, Whistling Kites and especially the Black-shouldered Kite. They’re big birds so they are easier to photograph.”

As well as birds, seven frog species have been found at the plant, including the Growling Grass Frog, which is endangered in Victoria.

The site also contains remnant Box Ironbark and Grassy Woodland vegetation.

We began work to upgrade the Back Creek Siphon pipeline, located near Malmsbury, in June 2011, almost 90 years after the original concrete pipeline was built.

The original pipeline was constructed in 1921 and is an important piece of infrastructure, connecting two sections of the Coliban Main Channel across a 37-metre deep valley and under the weir across Back Creek.

The upgrade involved installing 600 metres of a new 1.3 metre diameter pipe inside the existing 1.5 metre diameter pipe to retain the historical significance of the pipeline and limit excavation.

After the new pipe was in place, grout was injected between the two pipes to fill the void and prevent movement.

Construction work is now coming to an end, with reinstatement work and preparation for pressure testing already underway, and we plan to have water flowing through the siphon this month.

We hope it will be at least another 90 years before it needs upgrading again.

This Blog was launched in December 2009 as the Managing Director’s Blog with a post about our pricing proposal for the next three years.

Since then we’ve continued to post on pricing and a whole range of other subjects from storages and flooding to projects and pine trees.

It’s been encouraging to see our visitor numbers steadily increase but we value what our customers and communities have to say and want more of your comments, opinions and suggestions.

Our region faces many important challenges with a growing population and changing climate.

Our vision is to be a leader in sustainable water resource management and add to the prosperity of our region.

We will continue to publish our Blog with various contributors writing about a variety of topics.

We hope you will join the conversation.

Thanks to everyone who has read and contributed to the MD’s Blog.

I’m leaving Coliban Water to move to Goulburn-Murray Water.

I’m sure this Blog will live on in a new form.
