Non-drinking water systems
A non-drinking water system provides water that can be of lower quality than drinking water but is still suitable for its intended purpose, such as watering parks, public and private gardens and in homes for bathrooms and laundries. Non-drinking water sources include groundwater, rainwater, stormwater, wastewater and greywater. They may need further treatment for the intended use.
The Department of Water supports the use of these systems, so long as they meet water quality standards for protecting public health and the environment and are commercially viable.
The department assists developers, local governments and industries in the planning and approvals process for non-drinking water systems through an approvals framework.
The step-by-step process coversconcept planning, design, approvals and implementation with a commitment by government agencies to work collaboratively in the approval process. The department can coordinate preliminary regulatory advice from relevant agencies to a proponent's proposed project.
The framework aligns with the Western Australia Planning Commission's 2008 Better urban water management framework, which recognises that water efficiency, reuse and recycling are integral components of water cycle management.
