HDD DELIVERS INDUSTRIAL WATER SCHEME
In February 2014 UEA’s trenchless division was awarded a design and
construction works package for the Hunter Water Corporation as part
of the Kooragang Industrial Water Scheme (KIWS). The KIWS project
provides 9 mL per day of high quality recycled water to industrial users in
the Kooragang Island area to substitute the use of drinking water during
manufacturing.
The scheme was achieved due to the construction of a new advanced water treatment plant and a
7.5 km water delivery pipeline, the majority of works being undertaken using Trenchless Technology,
including three horizontal directional drill shots (470 m, 610 m and 460 m), one guided bore
installation and sliplining of approximately 600 m of existing 500 mm cast iron mains.
UEA Trenchless completed works on 2.92 km of fully welded PE pipe from the new treatment plant
in the Steel River Estate, Mayfield West, to midway along Cormorant Road, Kooragang Island.

FEDERAL BUDGET HANDED DOWN
Treasurer Joe Hockey handed down the 2014-15 Federal Budget in May 2014,
raising speculation about the consequences for trenchless industries and the
infrastructure sector.
Transport infrastructure and the resources and energy sectors emerged
as big winners during the Budget announcement, with the Federal Liberal
Government announcing Australia’s largest ever investment in infrastructure.
The 2014-15 Budget will inject an $A11.6 billion Infrastructure Growth Package
to boost total infrastructure investment by Commonwealth, State and local
governments and the private sector, to over $A125 billion by 2019-20.
Infrastructure projects nationwide will directly benefit from the 2014-15 Budget announcements, .

HDD Project Problems
and Issues
by Peter Brown, Trenchless Advisor
Most construction projects can have their fair share of problems and issues and trenchless is
no different. The key to limiting these is through knowledge, correct pre-planning, design and
using a competent contractor. Here, we look at steps that can be taken to circumvent common
issues involved in horizontal directional drilling installations.
WHEN IN PRE-PLANNING stages, it’s
important to remember:
• Each and every HDD project should be
seen as site specific
• Knowledge is key, but sometimes a
little bit of knowledge is dangerous
• The project should always be seen as
a power, water, communication etc,
project. To the client the project is
an asset installation; it is not an HDD
project though they must both go
hand-in-hand.
• HDD is the method for installing the
asset, but the methodology must still
conform to the client’s requirements,
and transition to existing networks
It is usually not one single area where most problems and issues can occur, but over a range of different sections
as well as other existing asset and within a HDD project.
