• These working papers summarise the outcomes of technical studies undertaken as part of the Murrumbidgee Valley Water Efficiency Feasibility project. The working papers cover a broad range of topics, from water accounting, water saving approaches in the river system, near-farm and on-farm zones, and assessment of the socio- economic benefits and impacts of saving water. The key findings and recommendations from the working papers are summarised in the Appendices of The Business of Saving Water.

• Whole of catchment water and salt balance to identify potential water saving options in the Murrumbidgee Catchment : CSIRO.
  This working paper provides a description of the major features of the hydrologic system relevant to potential water savings and it quantifies potential water savings and salt movement within the system.

• Stock and domestic water - delivery enhancement strategies : Pratt Water.
  This working paper examines potential water savings from improvements to Stock and Domestic supply systems throughout the Murrumbidgee Valley.

• Financing case study - Yanco Creek rehabilitation project public/private potential joint venture- preliminary evaluation : Copernican Securities.
  This working paper focuses on possible options for the development of a public/private partnership to rehabilitate Yanco Creek and save water.

• Development approvals - draft State Environmental Planning Policy : Freehill, Hollingdale and Page.
  This working paper lists measures under the environmental planning laws required for implementation of the objects and principles of the Water Management Act 2004 to facilitate water savings.

• Murrumbidgee socio-economic profile : Bureau of Rural Sciences.
  This working paper reviews the socio-economic characteristics of the Murrumbidgee Valley through a secondary data profile of the human capital, human-produced economic capital and social and institutional capital of the Valley.

• Socio-economic assessment of water efficiency investments in the Murrumbidgee Valley : Centre for International Economics.
  This working paper evaluates the economic effects of a number of options of the Pratt Water Initiative in terms of increased regional income and employment. The linkage between various activities within the Valley provides information on changes in water use and availability.

• Murrumbidgee en-route storages : GHD.
  This working paper provides an overview of en-route storages in light of current relevant industry and legislative environments. It also presents a preliminary option for off-stream storage of 50 GL’s, assist in achieving environmental releases and meeting increased summer peak demands.

• Summer demand project, on-farm/near-farm storage, workshop - incentives, constraints and opportunities : Analysis Plus Consulting.
  This working paper documents the outcomes of a workshop which discussed a number of the operating paradigms within the Murrumbidgee system that are related to taking the peak off the summer demand curve.

• Regulatory interventions to maximise water efficiencies in the Murrumbidgee Valley : Baker and McKenzie.
  This working paper examines the relationship between regulatory reform of water entitlement trading markets in relation to private sector investment of water efficiency infrastructure projects.

• Hydrologic economic ranking of water saving options : CSIRO.
  This working paper evaluated alternative technologies for reducing on-farm and off-farm losses within the Coleambally and the Murrumbidgee irrigation areas overlying different subsoil and hydrogeological conditions.

• On-farm feasibility of conversion to water efficient irrigation systems in the Murrumbidgee Valley : Naturally Resourceful Pty Ltd.
  Through financial case-studies this working paper investigates the economic benefits for farmers on ‘typical’ horticulture and broadacre farms in the Murrumbidgee Valley in implementing changes on-farm to improve water use efficiency.

• Delivery technology to save water in the near-farm zone : John Wilson & Partners Pty Ltd.
  This working paper investigated diverting the main canal for the Murrumbidgee Irrigation area down stream from the Berembed Weir site as an option to reduce water losses from the system. The associated papers evaluate options for saving water in different areas of the Murrumbidgee irrigation area.

• Water supply and land use planning for sustainable water-efficient irrigation in the Murrumbidgee Valley - the Lake Wyangan case study : Umwelt (Australia) Pty Ltd.
  This working paper documents catchment information for Lake Wyangan and explores current and future irrigation activity in a development context.

• Water efficiency improvements through environmental farming systems : Charles Sturt University : Pratt Water.
  This working paper investigates innovative farming techniques that take advantage of natural processes. It outlines the main constraints, options for addressing these and procedures for facilitating change in the management of Australian farming landscapes.

• Murrumbidgee Valley ecological assessment : T Hillman.
  This working paper describes the Murrumbidgee in four broad zones and the impact of changed flow responses on the ecosystem. The working paper also examines options for achieving greater environmental benefits than at present.

• Pre-feasibility study into bio-diesel : Dennis E Toohey and Associates.
  This working paper examines the environmental and social costs and benefits and economic feasibility of an illustrative commercial biodiesel plant in the Cootamundra area.

• Sequential biological concentration - review : Dennis E Toohey and Associates.
  This working paper suggests potential locations for application of Sequential Biological Concentration as a management tool for drainage waters of the highly irrigated areas of the Murrumbidgee Valley.

• Feasibility of timber plantations in the upper Murrumbidgee catchment - a triple bottom line analysis : The Fifth Estate.
  This working paper documents the financial, environmental and social feasibility of establishing new industrial timber plantations on selected land within the Murrumbidgee Valley.
