Arm End uses HDD to preserve reserve

Arm End, a Tasmanian multi-use public recreation reserve, will use horizontal directional drilling (HDD) for the land-based pipeline crossings in its rehabilitation, revegetation and irrigation programs.

The program will deliver recycled water from the Blackman’s Bay water treatment plant to anyone on the South Arm peninsula, bringing a water capacity to the fertile South Arm soils that has never been seen before and increasing its farming potential.

To minimise construction impacts on the local environment, the pipeline will be installed using HDD for land based and costal crossing sections, and a float and sink construction methodology for the marine sections.

Arm End has the support of, and in May signed a Memorandum of Understanding with, Tasmanian water utility TasWater.

While water rates are still to be confirmed, costs will likely remain low as the water is currently sent to into the Derwent River by TasWater.

The cost to users includes pipeline upkeep and maintenance based on a proportional per use scale; however, as the major user, Arm End will pay for most the operational costs.
