The West Australian Water Corporation says it will be ready for dry times around the town of Denmark next summer, with work to begin on new desalination plants soon.

The southern Western Australian town recorded it second driest year ever in 2014, but a new infrastructure project is set to secure supplies for next time.

There are plans for a 3.4 kilometre pipeline and two reverse desalination units to add an extra 650 million litres each year to Denmark’s water supply.

Water Corporation spokesperson Andrew Kneebone says the plans are progressing after talks with the Denmark Shire over the disposal of salty water, a byproduct of the desal process.

“The approvals there were really about informing the local authorities about what we're going to do with the brine and how we're going to dispose of that and getting their permission to use some pieces of land but it's not actually anything that's got us on hold,” he said.

Mr Kneebone said efforts would continue, with a goal of having more secure supplies by next summer.

“The major point that will secure the long-term supply for Denmark is the interconnection between the Denmark River Dam and the Quickup Dam which allows us to make use of the flows through the Denmark River that we wouldn't have been able to capture previously,” he said.

The project still requires a number of approvals.
