Case Study Presentations
Irrigation Australia will be introducing case study presentations by leading experts on issues that often confront the industry, detailing how these matters were successfully resolved and improved the efficient use of water. Industry suppliers will showcase their leading products in an exhibition format during the first two days of the event.
KEVIN PAGE | CITY OF GOLD COAST
Executive Coordinator Integrated Water Planning Water & Waste
Recycled Water Network Expansion Project. This project will be rolled out in the next 2-3 years and will target the cities greenspace (parks, schools and sporting fields) for irrigation with high quality recycled water. The recycled water will be significantly lower cost than drinking water and be completely climate resilient. The new network will heavily rely on technology to enable the smart and efficient operation of an irrigation system and its variable demands. There will be a strong focus on sustainable water management with smart metering utilised to ensure costs are reduced to minimum with no wastage.
BJORN BAKER | HYDROPLAN
Value in Irrigation monitoring and having an Irrigation Maintenance Plan
70% of all freshwater used globally is used in irrigation. An irrigation system that is poorly maintained results in water being wasted and not reaching its intended use. With much of Australia still in drought it has never been more important to keep irrigation systems well maintained in order to minimize wastage and to improve plant health through uniform and efficient irrigation. A key to keeping an irrigation system well maintained is monitoring its performance over time.
DAN MOSBAUER | CAIRNS REGIONAL COUNCIL
Smart Urban irrigation Project
This project involves conducting ground surveillance of 16 irrigated locations throughout Council. Providing data such as soil moisture, salinity and infiltration rates and allowing us to know where irrigation is needed, the duration of watering required and mitigating against nutrient leaching into the eco-system. Installation of new infrastructure will be required with new IQ site controllers, 6 moisture sensors, 3 weather stations and 9 flow sensors that in conjunction with 9 master valves will automatically respond to the real time conditions- altering/preventing irrigation programs. All of this data will be communicated to a centrally controlled management system which in turn will automatically respond to the current conditions- altering or shutting down irrigation programs when issues are detected. The challenge for this project will address being one of the first to use technology of this kind to become an Urban leader in irrigation on a national scale but locally provide solutions to the increased water demand to the Cairns Region.
JOHN BUSSELL | SWAN SYSTEMS
Data-Based Decisions for Irrigation Management
Irrigation enterprises accumulate significant volumes of data. The data becomes a valuable resource when used to provide insights for irrigation and nutrient application decisions. Combining accurate, local weather forecasts with data that most operations are automatically collecting daily can enable resource usage optimisation, water savings, better yields, reduced operational costs, and sound environmental stewardship.
ANTHONY LONG | HYDRAWISE FOR HUNTER INDUSTRIES
Remote Management of Residential and Commercial Customers Saves Water and Grows Your Business
Utilising modern tools and internet based controllers, helps to grow contracting businesses with the benefit of saving water. Contractors and Multi-Site managers are now able to remote access multiple controllers. Utilising tools like the Hunter Hydrawise software provides management opportunities, the ability to increase business and services offered to customers and massive water savings for clients.
IAN HASSELMAN | CITY OF PARRAMATTA
City of Parramatta Environmental Sustainability Strategy- Policy into Practice
The topic of my presentation will be about the journey City of Parramatta is on regarding water management. Since council amalgamation the demographic and area which makes Parramatta has changed. Council has set significant corporate goals to meet this new communities values. Now we are faced with the challenges in taking these strategic goals and making them happen. At Parramatta we are focused on gaining a deeper understanding of how we use water through a holistic review of usage in Parramatta. We are trailing the use of new technologies such as real-time metering and sensors through a LoRaWAN network. Parramatta is also then looking at the future including climatic and population changes and growth. I will discuss the challenge is linking the organisational vision and aspirations to a successful delivery plan which meets the future state of Parramatta.
Dr. Paul Lamble | Peak Water Consulting
The optimal approach for sports field irrigation systems
This case study compares the performance, lifetime costs of ownership (capital and operating costs) and qualitative playing surface outcomes for both design and construct and professionally designed irrigation systems based on key performance indicators. It also addresses the key advantages and disadvantages of both approaches to determine the optimal approach for sports field irrigation systems.
Jack Rea | Sunshine Coast Council
Centralised control system and smart irrigation project
I prepared a presentation last year on all of the work we have done in the last 4-5 years in getting us ready to implement our centralised control system and smart irrigation project. This is a major irrigation project running over 5 years and several million dollars. This has involved a huge amount of work on capturing asset data, condition rating, irrigation mapping, trialling CCS systems and how we have managed this process.
Scott Johnstone | HydroPlan Pty Ltd
Value of Irrigation Assets Specifications for Councils
Councils vary in scale of irrigation assets and culture. For councils that actively own, manage and maintain irrigation assets in their public open spaces, recreational parks and/or sporting facilities it is not uncommon for the council managers and supervisors to oversee multi-million dollar of irrigation assets plus multi-million dollar operational budgets to irrigation inputs.
Ben Walsh | Bio-Remedy
Water Body Management and Water Quality
Presentation of three case studies about water quality of dams and theory of quality of irrigation water. The three case studies are:
- Ibrox Park Nursey- Irrigation Dam circulation for planktonic algae management
- Amgrow PTY LTD- Wastewater Dam aeration and biological remediation for water quality and nutrient reduction
- Brisbane City Council- Stormwater Retention basin solar powered circulation for algae management.
Sundeep Bhatt | CHT Australia
Manipulating Hydraulic Conductivity in Order to Improve Soil Health and Structure for Turf
Many turf growers and farmers are on the lookout for new ideas to overcome difficulties that have frustrated them for years. This session will discuss the innovations in chemistry that some farmers are using and many are now thinking about to help their business.
First and foremost, all farmers and turf managers alike are concerned about getting the right amount of water when and where they need it, but the soil often works against them. Too much run off. Too little infiltration. Too hard a surface. Resulting in such a complex use of chemicals; that need not be the case. Perhaps there just is not enough water, so how do we make the available water go further for us?
This presentation will introduce data from case studies that shows that the soil behaviour can be changed to allow better management of irrigation programs which will then allow the real optimisation of fertigation systems that deliver serious cost and yield benefits to the operation.
We will show how YOU can influence your soil behaviour by varying the hydraulic conductivity AS YOU WANT IT TO BE.
Will Marcus | Director of Blue Ring and Managing Director of ARGO Architects + Engineers and Master Planners

Joel Spry, Power Water Corporation, Demand Management Coordinator
Changing water demand through Garden Tune Up’s
The Darwin population uses more water than can be captured and supplied in the long term. With very high per capita water use, a growing population and unpredictable wet seasons consumption is becoming even less sustainable. Most water used in the region is non-essential with approximately 70% of residential water use going on gardens (57%) or leaking (12%). The general Darwin culture has traditionally had little concern for water efficiency as the region has a very high annual rainfall and relatively low historical costs per kilolitre.
Rather than invest in expensive new water sources Power and Water started the Living Water Smart demand management program to work across the community to reduce demand to a more sustainable level.
One of the innovative approaches undertaken to achieve social awareness and behavioural change was to the introduction of the Garden Tune Up rebate program. This program was devised and introduced in 2017 and is greatly contributing towards the delaying of new water source augmentation in Darwin as well as protecting the water supply in Katherine.
The program is delivered in partnership with 30 local expert irrigation businesses and to date has achieved nearly 500,000,000 litres in water savings for Power and water customers.
A $300-$500 rebate is available to eligible customers for an irrigator to provide specialist irrigation and garden services such as setting an efficient watering schedule, advice on plant selection and plant and soil health.
A new approach to using Geospatial data systems has been utilised to gather, manage and analyse data to track program performance and water savings; resulting in being awarded National and International awards for innovation.
As a first of its kind in the Northern Territory, the Garden Tune Up Program has economic, social and environmental benefits in line with government priorities to deliver community benefit and promote ecologically sustainable development of the Northern Territory by:
- greatly contributing towards the delaying of new water source augmentation in Darwin as well as protecting the water supply in Katherine
- generating business for local irrigation industry and increasing skills capacity;
- providing cost savings to Territorians;
- raising awareness of, and influencing long term water use behaviour; and
- utilising innovative technology to create efficiencies within Power and Water Corporation.
Richard Dilena | City of Greater Geelong
Irrigation Management Officer
Picking up the theme of provision of functional green assets in the community, I will be taking a look at an example of a recent irrigation project in a passive green space which includes turf and garden beds using a variety of irrigation hardware, basically a typical small community park. The project was designed to use captured and stored rain water off the roof of buildings, supplemented by a potable water supply, to do the irrigation. What was the planning process, what was the outcome, what was the reality. I’m looking forward to it!
Greg has a background in shipping and transport logistics, Jackie has many years experience in international trade and shipping, while Kieran has formal horticultural qualifications and over 33 years of horticultural experience. Greg, Jackie and Kieran are proud of the friendly and supportive workplace they have cultivated and believe it directly results in the high level of productivity achieved from the nine staff members. Staff are quick to identify the friendly work atmosphere and good communication from the owners as a key to the happy and stable workforce.
The nursery is currently a member of the ‘Nursery & Garden Industry Queensland’. Kieran has served in the role of NGIQ board member and is a former president of the local Sunshine Coast branch of NGIQ. Kieran is currently active on a number of event committees including ‘Brisbane Trade Day’ and ‘NGIQ Green Expo’.
It is our view, formed with reference to current monitoring and emerging science, that a ‘business as usual’ approach will not be sufficient to mitigate the impacts of population growth and climate change and is not achieving the liveable places we aspire to.
The presentation will cover the drivers for action, and the actions being lead by the CRCWSC. Preliminary case studies of the implementation actions at one or more of the State Priority Development Areas in Queensland with a focus on how these achieve liveability will be included
