CHW chief executive officer Neil Brennan said talks with farmers about the depth of the pipe had been constructive.

"We have kept dialogue going with the farming community.

"I think (it's) one of the big things for us now that the project is under way. You just have to look at how we are going with the construction and look at the re-instatement and how we are keeping to our word in the Wombat

State Forest," he said.

"We know that it's stressful for them (farmers). The corner stone is to keep the community open which is what we are trying to do.

"I'd think they have been fine,There are areas we disagree on and that's fine, it's always going to happen on major projects."

The project has been controversial in the region. Farmers met in March to air their criticisms on CHW's consultation process CHW.

Hepburn Shire acting mayor Tim Hayes recently launched a petition to protest against CHW's proposed water increases and the superpipe.

"We have got about 150 signatures at the moment. We have had it out since last Wednesday so people have been searching me out to sign the petition," Cr Hayes said.

Meanwhile aifThe Advocateaif was recently given a behind the scenes look at construction in the Wombat State Forest.

Building the 100km pipeline is not as easy as digging a hole in the ground and laying the pipe.

CHW has co-ordinated its construction with numerous authorities and land-holders.

Working in the Wombat State Forest means the Department of Sustainability and Environment, the Environment Protection Authority, a zoologist and archaeologist are closely involved.

The pipeline is following a 20m powerline easement through the Wombat State Forest. The steel 760mm pipes are expected to have a lifespan of 100 years and are buried in a trench more than a metre deep and buried with sand.

About 250 cubic metres of sand is being used everyday in the forest. The sections of pipe won't leak because of a rubber ring that seals the sections together as they are laid.

Spotters work on-site to ensure the 25 pieces of heavy machinery or people do not come in contact with high-voltage powerlines.

Software and a GPS unit in the machinery digging the trenches means contractors know the alignment, depth and grade they should be following.

CHW chief executive officer Neil Brennan said the project was on time,and on budget.
