Re-plumbing irrigation in the

Murray Darling Basin; an analysis of five years of Australian

Government investment

Richard McLoughlin

Murray Darling Basin Plan

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.

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.

Up by as much as 450 GL

('efficiency measures' with no adverse effect on social or economic outcomes)

Down by as much as 650 GL

('supply measures' that achieve environmental outcomes with less water)

Any shortfall below 650 GL will be recovered from 2016

SRWUIP Infrastructure

 The majority of rural water infrastructure funds have been committed to projects in the Murray-

Darling Basin for improving the operation of offfarm 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

• Community/industry support for irrigation infrastructure investment programs is generally strong

• creates jobs during roll-out

• underpins long-term viability and economic sustainability of irrigation industry and regional communities.

• Completed projects have demonstrated improved productivity benefits:

• increased crop rotation ability

• reduced labour costs

• increased crop water use efficiencies

• improved soil management

• reduced maintenance

• reduced weed control requirements

• farmer’s share of water savings available for production

Monitoring and Evaluation – NSW PIIOP example

Regular contact with grantees to discuss progress and issues

Milestone payments with evidence of completion of works and audited financial reports

Financial reviews to ensure contract compliance

Workplace Health and Safety reviews to ensure implementation of legislated requirements

Visits by department staff to view works

• Assisting grantees to provide detailed information on the program’s key performance indicators

Analysis of SRWUIP investment in Centre Pivots

• Initial analysis of 130 centre pivot irrigators funded under SRWUIP.

• In general, costs decrease with increased area under irrigation.

Commonwealth of nearly

30GL.

• Reduced ‘boom or bust’ extremes of water supply

Lachlan Catchment Management Authority

• Regional delivery partner coordinating irrigators around

Parkes NSW
