First published in 2024, the Water conservation cost-benefit analysis (CBA) guidelines provide an economic tool for water utilities to use when identifying and deciding which water conservation measures will best serve their communities. 

Under Action 2.2 of the Roadmap, we have published a new addendum to these guidelines that focuses on evaluating recycled water initiatives. The addendum outlines a consistent approach to undertaking CBAs for water recycling projects, including stormwater harvesting. It provides a step-by-step methodology for assessing costs and benefits, with a focus on wastewater and stormwater recycling investments, and includes a catalogue of values to support economic evaluation. This guidance aims to improve consistency and transparency in the economic assessment of water recycling projects across NSW.

People in a meeting

Responsibility for and oversight of recycled water is shared across several NSW Government departments and regulators. In recognition of this shared responsibility, the department has established a cross-government Recycled Water Coordination Committee to support the expansion of water recycling across NSW.

Work in progress

  1. Review of incentive programs to increase use of recycled water

    This literature review is investigating potential incentive programs to increase the use of recycled water in NSW. We are looking at different examples across Australia and internationally and the key findings will be considered in the NSW context. 

  2. Updated NSW Guidelines for Recycled Water Management Systems and recycled water information sheets

    Local water utilities will be able to use these new guidelines and the accompanying 13 information sheets to meet the approval requirements for recycled water schemes. 

  3. Map of water recycling schemes in NSW

    The interactive map will identify where current water recycling schemes are currently operated and where there may be future capacity for water recycling in NSW. 

  4. Commercial recycled water user guide

    This guide will explain how large water users, such as industrial facilities, agricultural enterprises, and commercial operators, can approach local water utilities in their area to obtain a recycled water or treated effluent supply.

Frequently asked questions

How is recycled water regulated in NSW?

Responsibility for and oversight of recycled water is shared across several NSW Government departments and regulators.

Why is recycled water important?
  • Water is our most precious resource. Climate change means that NSW will confront more frequent and more severe droughts, higher temperatures and more storm events. To prepare, cities and towns will need to transition to more secure water supply options, diversify water sources and increase the proportion of water that does not depend on rainfall. This includes increasing water recycling. 
  • By being water wise and recycling more water in our urban environments, we can secure water supplies to meet the needs of growing communities. 
What is the NSW Government’s vision for the future of water recycling in NSW?

The NSW Government vision is that:

  • utilities will consider recycled water equally with other supply and demand options
  • increased delivery of recycled water solutions will improve diversity, resilience and environmental water quality
  • communities will understand water recycling options and engage with utilities in the conversation on purified recycled water for drinking.
What is the Recycled Water Roadmap?
  • The Roadmap outlines the government’s vision for expanding water reuse across the state, ensuring a robust policy and regulatory framework is in place for future projects.
  • It includes 14 proposed actions across 5 key priority areas to address barriers and pave the way for increased and expanded recycled water use in future, including for drinking and non-drinking purposes, where it is safe, beneficial and cost-effective. 
  • The Roadmap actions are to be delivered by June 2027, with ongoing monitoring to identify new opportunities beyond the Roadmap. 
     
What are the barriers to expanding recycled water projects?

The barriers identified in the Roadmap were developed through consultation with Sydney Water, Hunter Water, WaterNSW, private and local water utilities, local councils, peak bodies, academics and relevant government agencies.

The barriers are categorised in 7 broad areas:

  1. Governance and regulation.
  2. Economics and pricing.
  3. Investment risks.
  4. Community acceptance.
  5. Skills and capabilities.
  6. Integration with land use planning.
  7. Environmental challenges.

You can read more about these barriers in the Recycled Water Roadmap.

How does the Roadmap propose to address the barriers to water recycling?

The Roadmap set out 14 actions across 5 key priority areas:

  • Priority area 1: Putting in place state-wide planning and policy frameworks that support integrated planning for recycled water.
  • Priority area 2: Providing tools and resources to support planning and delivery of recycled water solutions.
  • Priority area 3: Creating clear regulatory and approvals processes for recycled water.
  • Priority area 4: Building capacity and capability across the water sector to plan and deliver innovative recycled water solutions.
  • Priority area 5: Taking steps now so that purified recycled water is an option for our future drinking water supply.
How will we know whether the Roadmap has achieved its aims?

The department will undertake an evaluation of the Roadmap in 2027 to assess its impact in 5 areas: effectiveness, efficiency, appropriateness, legacy and equity.

How much wastewater is recycled in NSW?

In 2023-24 NSW, public, local and private water utilities produced 82.8 gigalitres (GL) of recycled water (this is about the same amount of water that 46,000 homes use in a year). 

This recycled water was used for non-drinking purposes such as:

  • irrigation for gardens, open public spaces and in agriculture
  • commercial uses such as washing hard surfaces, dust suppression, and cooling of buildings
  • domestic use for toilets and washing machines
  • firefighting.

All recycled water supplied by a water utility must meet Australian Guidelines for Water Recycling.

What are the benefits of water recycling?

Water recycling can deliver a range of benefits now and into the future. We know we need to make better use of our water resources, think innovatively and find ways to deliver liveable communities and fast-track housing for a growing population. The benefits include:

  • Increasing water security and resilience
  • Reducing reliance on drinking water and supporting urban greening
  • Reducing wastewater discharge to waterways and pressure on wastewater systems
  • Contributing to energy creation, resource recovery and circular economy
  • Supporting new industries with fit-for-purpose water
  • Managing local flooding

Recycled water can be a key part of our future water supplies, and delivering the Roadmap will put us on the path to unlocking the benefits.

Is recycled water safe to drink?
  • Purified recycled water is recycled water that is further treated to ensure that it is safe for human consumption. Currently there are 40 cities in the world, including Perth, where purified recycled water is used in the drinking water supply.
  • Although we know purified recycled water is safe to drink, extensive community engagement is required to gain public trust and confidence in the safety of the water for consumption. Stringent water quality assurance programs and approvals need to be in place before water is provided to consumers.
  • Sydney Water, Hunter Water and some regional water utilities are currently engaging with their customers on the future of their water supplies, including discussion on adding purified recycled water into their drinking water supplies.
  • The Roadmap includes actions to clarify the regulatory frameworks across NSW government agencies, engage with industry and research sectors and to support utilities to undertake best practice engagement with their customers on purified recycled water, learning from interjurisdictional and overseas experience.
How was the Roadmap developed?

The NSW Government undertook extensive consultation with Sydney Water, Hunter Water, WaterNSW, private and local water utilities, local councils, peak bodies, academics and relevant government agencies to develop the Roadmap. 

The What we heard report and What we heard summary details the valuable feedback that we received on the draft Roadmap from the survey, written responses and webinars. 

The key themes that emerged from the feedback were that the final Roadmap should:

  • acknowledge the role that local councils and private sector utilities play in the delivery of recycled water infrastructure
  • make clearer links to Integrated Water Cycle Management and Circular Economy principles
  •  consider how recycled water can contribute to greening and urban cooling, including in the context of new housing developments
  • place more emphasis on the importance of engagement and education
  • provide greater clarity on timeframes and actions.

In general, a vast majority of the feedback supported government taking more action to increase water recycling in NSW, with some saying that they would like to see the visions and actions go further.
