Wivenhoe recycled water pipeline in 'mothballs' ...

Water recycling pipeline in mothballs

8 May 2009

A 16km pipeline of recycled water is ready to pump the liquid the final 100m into southeast Queensland's drinking supply but that may never happen.

The pipeline leading to Wivenhoe Dam, the main source of the region's drinking water, has been built, tested and commissioned as part of the Bligh Government's $2.4 billion Western Corridor recycled water project.

But the pipeline, meant to carry purified recycled water from Lowood to the dam, was effectively mothballed as soon as it was built due to the Government's decision to put recycled water into the drinking supply only as a last resort.

Completed before the Government backflipped on its recycled water policy last November, the pipeline was still commissioned, with the operator, Watersecure, testing it for leaks and signal faults.

The 1.2m-diameter pipe is now full of recycled water, ready to deliver it down a 100m cascade into the dam.

Premier Anna Bligh last November reversed her position on putting recycled water into the region's drinking water.

After insisting for months during the region's drought that there was no other option than to top up southeast Queensland's then shrinking dam system with recycled water, she announced the Government would only use it as a last resort.

The Queensland Water Commission has recommended that the Government consider adding purified recycled water to the drinking supply when dam storage levels drop to 40 per cent.

On current estimates, this will not happen until December, 2010, even if the region suffers a repeat of its worst rainfall period on record.

The Swanbank and Tarong power stations remain the only consumers of purified recycled water despite the Government spending $2.4 billion on the western corridor project.

The project is designed to produce up to 232 megalitres of recycled water a day but is currently only delivering an average of just over 112 megalitres a day to the two power station companies,
with no new customers for its product in the offing.

A spokesman for Watersecure said the pipeline, which has been specifically built to supply recycled water to the dam, had been "dry and wet commissioned", but no recycled water was released into the dam during any testing.

I have an idea why don't they discount the cost of the recycled water and sell the balance off to the Lockyer Valley farmers as they were meant to do in the first place.
I am sure that's what got the recycle water plan going. They want and need the water but not at this price.
