Acts & regulations

The NSW Department of Planning, Industry and Environment is conducting a five-year statutory review of the Water NSW Act 2014 (the Act). The review will help determine whether the Act is effective and whether it enables WaterNSW to deliver water in an efficient and safe manner.

Managing New South Wales water resources relies on a range of legislation, initiatives and cooperative arrangements with the Commonwealth and other state governments. The key piece of legislation for the management of water in NSW is the Water Management Act 2000.

Water Management Act 2000

The object of the Water Management Act 2000 is the sustainable and integrated management of the state's water for the benefit of both present and future generations.

The Water Management Act 2000 is based on the concept of ecologically sustainable development – development today that will not threaten the ability of future generations to meet their needs. The Act recognises:

  • the fundamental health of our rivers and groundwater systems and associated wetlands, floodplains, estuaries has to be protected
  • the management of water must be integrated with other natural resources such as vegetation, soils and land
  • to be properly effective, water management must be a shared responsibility between the government and the community
  • water management decisions must involve consideration of environmental, social, economic, cultural and heritage aspects
  • social and economic benefits to the state will result from the sustainable and efficient use of water.

The Water Management Act 2000 recognises the need to allocate and provide water for the environmental health of our rivers and groundwater systems, while also providing licence holders with more secure access to water and greater opportunities to trade water through the separation of water licences from land. The main tool in the Act for managing the state's water resources are water sharing plans. These are used to set out the rules for the sharing of water in a particular water source between water users and the environment and rules for the trading of water in a particular water source.

Regulations, proclamations and orders under the Water Management Act

To assist in implementing the provisions of the Water Management Act 2000, regulations, proclamations and orders are also made.

Regulations under the Water Management Act

The key regulation made under the Water Management Act 2000 is the Water Management (General) Regulation 2018. 

The regulation specifies important procedural and technical matters related to the administration of the Act, and also specifies exemptions from licence and approval requirements under the Act.

The regulation provides for Strahler stream order to be determined for the purposes of the regulation by reference to a stream order database which is published on the department’s website.

A Regulatory Impact Statement (PDF, 417.66 KB) was prepared during the latest review of the regulation which included a review of the objectives, options, assessment of costs and benefits, and the outcome of public consultation.

Proclamations under the Water Management Act

A range of proclamations have been made which commence the licence and approval sections for water sources following the commencement of the relevant water sharing plan.


The Minister can publish orders to implement specific details of an Act. Orders are published in the NSW Government Gazette on the NSW legislation website.

The Access Licence Dealings Principles Order 2004 provides detail and clarity for dealings permitted under the Water Management Act 2000 and in relevant water sharing plans.

Significant decisions involving discretion made under the Water Management Act

NSW makes a number of significant water management decisions under the Water Management Act 2000 that involve discretion.

To provide greater transparency and accountability of water sharing and extraction arrangements, a reporting framework has been developed for identified significant water management decisions involving discretion, including how and when reporting will occur.

Water Supply (Critical Needs) Act 2019

The Water Supply (Critical Needs) Act 2019 facilitates the delivery of emergency water supplies to certain towns and localities and to declare certain development relating to dams to be critical State significant infrastructure.

Further information is available on the department's webpage, Water Supply (Critical Needs) Act 2019.

Commonwealth legislation

The key piece of Commonwealth legislation relating to water is the Commonwealth Water Act 2007. Schedule 1 of the Act contains the Murray-Darling Basin Agreement, which the NSW Government is party to.

The Commonwealth Basin Plan 2012 was adopted under the Water Act 2007. Water resource plans are a key requirement of the Basin Plan 2012.

There are 22 water resource plans required to be developed in NSW and each plan varies in the number of resources, their level of development, number of environmental assets, and geography affecting the way the rivers are run in each area.

Delivering Water Resource Plans for New South Wales

Water resource plans will set out arrangements to share water for consumptive use. They will also establish rules to meet environmental and water quality objectives and will take into account potential and emerging risks to water resources.

NSW water resource plans will meet the minimum requirements of the Commonwealth Water Act 2007 and Basin Plan. Each water resource plan must:

  • Describe all water rights in the plan area.
  • Demonstrate how compliance with the Sustainable Diversion Limit (SDL) prescribed in the Basin Plan will be assessed and maintained.
  • Include a Water Quality Management Plan.
  • Provide for environmental watering.
  • Address risks to water resources identified in a risk assessment.
  • Explain how essential human needs will be met in extreme events.
  • Take account of Aboriginal people’s water dependent cultural values and uses.

Many of the water resource plans will also include a water sharing plan.

The NSW Government has always advocated for a true triple-bottom-line approach to the Murray-Darling Basin Plan, which balances economic, environmental and socio-economic concerns, and puts local communities first.

The development of NSW water resource plans will adhere to these fundamental principles, with stakeholder and community consultation at the forefront.

This includes the opportunity to comment on each water resource plan's Status and Issues paper and each draft plan. Targeted consultation including with Stakeholder Advisory Panels (SAPs) is also being undertaken.
