Re-plumbing irrigation in the Murray Darling Basin; an analysis of five years of Australian Government investmentRichard McLoughlin
The Government has committed to implementing the Murray Darling Basin Plan on time and in full.
This includes the commitment to bridge the gap by recovering 2750 GL LTAAY of water for the environment.
Murray Darling Basin Plan
Sustainable Rural Water Use and Infrastructure Program
The Government’s vehicle for water recovery.
Over $10 billion
Water savings are recovered for the environment in order to ‘bridge the gap’ to the sustainable diversion limits under the Murray Darling Basin Plan through three main components:
Three components:
1. Irrigation infrastructure projects; 2. Water purchase and 3. “Supply measures”

Any shortfall below 650 GL will be re-covered from 2016
Up by as much as 450 GL ('efficiency measures' with no adverse ef -

SRWUIP Infrastructure
The majority of rural water infrastructure funds have been committed to projects in the Murray-Darling Basin for improving the operation of off-farm delivery systems and helping irrigators improve on-farm water use efficiency.
Water savings are shared between the Australian Government for environmental use and irrigators for consumptive use, supporting increased productivity and economic activity in regional communities.

Designing rural water infrastructure programs
• Consultation with industry has helped ground programs in local/industry experience
• Programs like NSW Private Irrigation Infrastructure Operators Program (PIIOP) see locally-driven design for major system refurbishment
• Fit for purpose and meeting local needs• Design built on good planning• Sound technical underpinning• Properly costed• Competent project management• Positive cost benefit
Types of Infrastructure Projects
– Planning, investigations and project design
– Works on irrigation systems off farm - modernisation and rationalisation
– Works on farm to improve water use efficiency
– Works to improve ecological health and restore natural flows
– Water saving municipal projects – e.g. storm water harvesting
Who are delivering the projects?
State government departments e.g. water, primary industry, environment
Irrigation infrastructure operators Irrigation industry associations Industry commodity bodies
e.g. rice-growers, tomato growers Individual irrigators Catchment management (resource management) authorities
Local government Water utilities CSIRO (sustainable yields studies)
Upgrading irrigation systems off farm
Works to improve efficiency and timeliness of irrigation water delivery , e.g.
– Fixing/replacing leaky old systems– Lining channels or replacing channels with pipes– Automation to improve water delivery– Metering upgrades to meet modern efficiency standards– Reconfiguring and rationalising channel systems and farm off-takes
Examples:• Vic Goulburn-Murray Connections Program• NSW Private Irrigation Infrastructure Operators Program
Upgrading Irrigation Systems On farm
Works on farm to deliver and use water more efficiently and increasing productivity, e.g.
– Improving on farm storage and tail water recirculation system– Installing pipes and risers– Installing drip irrigation systems and centre pivot irrigation as an alternative to the
traditional flood irrigation
Examples:• On-Farm Irrigation Efficiency Program in the Southern Basin• Victorian Farm Modernisation Program • QLD Water Use Efficiency Program• NSW Pilot - Farm Modernisation in Gwydir & Border Rivers
Benefits from irrigation infrastructure investment
1.Community/industry support for irrigation infrastructure investment programs is generally strong
i. creates jobs during roll-out
ii. underpins long-term viability and economic sustainability of irrigation industry and regional communities.
2.Completed projects have demonstrated improved productivity benefits:
i. increased crop rotation abilityii. reduced labour costsiii. increased crop water use efficiencies iv. improved soil management v. reduced maintenancevi. reduced weed control requirementsvii. farmer’s share of water savings available for production
Monitoring and Evaluation – NSW PIIOP example
1.Regular contact with grantees to discuss progress and issues
2.Milestone payments with evidence of completion of works and audited financial reports
3.Financial reviews to ensure contract compliance
4.Workplace Health and Safety reviews to ensure implementation of legislated requirements
5.Visits by department staff to view works
6.Assisting grantees to provide detailed information on the program’s key performance indicators

pumps, automation and soil monitoring
• On-farm water use reduced from 10ML/Ha to
6ML/Ha.

catchment
• Targeted “whole of system” approach to channel distribution system and
on- farm water loss.
• Returned water savings to the Commonwealth of nearly 30GL.
• Reduced ‘boom or bust’ extremes of water supply
Lachlan Catchment Management Authority
• Regional delivery partner coordinating irrigators around
Parkes NSW
• Implemented a water storage and reuse scheme
utilising lateral move irrigators
• Reduced water use by 3.7ML/Ha
• Enables consistent production level and increased
financial sustainability
Where to next?
• Release of the Water Recovery Strategy
• Government priority for future recovery of water through infrastructure investment.
• Work with Basin States to develop proposed projects, such as environmental works and measures, that can deliver Basin Plan environmental outcomes with less water, thus leaving more water available for consumptive use.
