Construction of the pipeline to secure Denmark’s long term water supply is in full swing

To build the 43km pipeline, a number of crews will work simultaneously at different locations , and will lay around 7,186 lengths of 6 metre pipe from Albany to Denmark. Weather permitting, around 400 metres of pipe can be installed each day; that’s 2 kilometres every week.

Building the pipeline

Most of the pipeline will be installed by digging open trenches, with horizontal directional drilling (HDD) used to go under Quickup River and Hay River. Also known as trenchless construction, HDD is a drilling method used to install the pipeline without impacting the natural waterway.

Minimising impact at river crossings

HDD will be used at river crossings along the route, to minimise construction impacts. To do this, we will excavate a small pit in the paddocks on each side of the river. A drill head will bore through the earth from one side of the river, drilling deep under the river and back up to ground level on the other side. The drill head is guided by GPS and other sensors to ensure we reach the required depth under the river and drill through the second pit on the other side.

By late August, we expect to install almost 8km of pipeline to connect Denmark to the Lower Great Southern Town Water Supply Scheme.
