GATESAWMA’s Combination Gates provide the benefit of combining overshot flow regulation and undershot water drainage with the ability to completely remove all gates from the waterway for unobstructed flow.
The dual leaf gates will be operated using the AWMA Hydraulic Power Pack (HPP). Due to the number of gates to be managed and geographical isolation of the sites, incorporation of AWMA’s HPP provides significant savings in energy, infrastructure and investment.
Three new regulators and three levees have been constructed to retain environmental water within the lakes and surrounding floodplain. An
existing regulator has been refurbished to provide some flexibility in the management of smaller volumes of water in the most southern lakes. The infrastructure will allow restoration of a more natural flooding regime to the Hattah Lakes, with small floods provided every 2 to 3 years and larger floods every 8 years (when water is available).
This project is a joint initiative of the Mallee Catchment Management Authority, Department of Sustainability and Environment, Murray-Darling Basin Authority, Goulburn-Murray Water and Parks Victoria. Photo courtesy of Comdain Infrastructure.
FOR ENVIRONMENTAL WATERCOMBO
Dual leaf Combination Gates up to 6.5m high x 2m wide, along with Segmented Stopboard structures were custom designed, manufactured and installed for five sites within Victoria’s iconic Hattah Lakes.
NEW FLOOD READY DESIGNS
GENERALLYSPEAKING
State Water’s Wakool Regulator is to be replaced, as the existing structure
is in a state of disrepair. Being in a flood prone area, the design criteria for
a new water regulation structure specified the protection of the asset from
damage caused by rising water levels and floating debris.
The new 4in1 LayFlat is 4.7m deep, 12m wide and over 3m high. It will comply
with current OH&S requirements and provide better operational control and
operators’ safety.
The LayFlat’s actuation components are connected to a tamper-proof cabinet
containing hydraulic controls complete with isolation options. Operation is
available via AWMA’s portable petrol powered Hydraulic Power Pack (HPP).
The HPP further reduces the need for expensive infrastructure to be exposed
on site.
The hydraulic cylinders have been fully encased within the central piers, the
handrails are collapsible and the access platform removable.
Due to these design aspects, in the event of storms or floods, the asset can
be protected from water and debris damage.
The Australian water industry is very diverse, incorporating
water treatment, waste water, storm water, flood,
desalination, irrigation, environmental and more.
The range of water control infrastructure required to service
the industry along with the asset owners also varies greatly.
One thing that can assist in making things more coherent
is a common technical specification for water control
infrastructure.
There are a number of dedicated proprietary specifications
developed by major water authorities and many adhoc
specifications that are project specific. Most projects
refer to American and British penstock Standards which
are outdated and not relevant to the expectations of the
Australian water industry. There is no Australian penstock
specification or Standard.
AWMA has taken this to task, revised existing proprietary
specifications and worked with a number of industry
players to develop what could become the basis of the first
national Penstock and Stop board technical specification.
The “Australian Technical Specification for Fabricated
Water Control Infrastructure” has been developed to
provide standardisation of the design of water control
infrastructure across all sectors of the water industry.
The primary beneficiary will be the asset owners, but it
will also assist designers, consultants, constructors and
manufacturers.
This document has been created for the industry to use, and
is now available from the AWMA website.
AWMA acknowledge that it is a challenging task to cover
all areas of such a diverse industry. We therefore value your
feedback and comments to further develop this document
into a truly national specification and valuable tool for all to
use.

State Water’s custom designed AWMA Multi-Bay LayFlat Gate ensures all protruding components are collapsible, removable or encapsulated.
AWMA are pleased to publish the initial release of the Australian Technical Specification for Fabricated Water Control Infrastructure.
This specification, jointly developed by members of the Australian water industry, has taken input from stakeholders including major water utilities, industry associations and other penstock manufacturers.
The aim of this specification is to provide standardisation of design and fabrication of water control infrastructure across all sectors of the water industry. It covers requirements for the design, manufacture, supply, handling, delivery and installation of fabricated water control infrastructure.
The primary beneficiary will be asset owners, but the specification will also assist designers, constructors, manufacturers and installers.

Stainless steel TLF Penstocks have been designed, manufactured and installed for Melbourne Water’s Dights Falls Weir Replacement and Fishway Project.
The TLF penstocks are required to isolate the fishway during maintenance
shutdowns. Positioned in a public area, the gates feature tamperproof
non-protruding actuation systems. The non-rising spindles are under
lockable covers for manual operation via extension handles.
The Dights Falls Weir and Fishway is located in Abbotsford, Victoria.
The fishway will open up the Yarra and its tributaries to many species of
migratory fish whose upstream passage has been restricted by Dights
Falls for decades.
AWMA were engaged by Fulton Hogan for the project delivered by the
Waterways Alliance on behalf of Melbourne Water. The Waterways
Alliance is a partnership between Ecodynamics, Fulton Hogan, SMEC
and Melbourne Water.
Over 40 sites will be replaced with fully automated water
management equipment. The new structures will be controlled,
monitored and managed using cloud based software, via secure
web access. All sites have been individually inspected to ensure
the most appropriate water control gate and operational solution
is implemented at each location. The federally funded Private
Irrigation Infrastructure Operators Program (PIIOP) project will
be delivered through the AIM (Advanced Irrigation Management)
Alliance and is due for completion in 2013.
