Queensland Plumbing and Wastewater Code guidelines For councils, plumbers, builders and developers A guideline to assist in the interpretation and application of the Queensland Plumbing and Wastewater Code Effective August 2009

QPW code guidelines for councils, plumbers, builders and developers 2 - Introduction Queensland’s ClimateSmart 2050 strategy has been developed to help the state address climate change. Through the ClimateSmart adaptation plan, the Queensland Government is working to ensure we have a secured future water supply. The Queensland Plumbing and Wastewater Code (QPW code) compliments the government’s commitment to water savings through the implementation of a wide range of measures including sub-meters, expanded use of treated greywater and blackwater re-use trials. In an aim to help protect and conserve the state’s water resources the Queensland Government will introduce a new version of the Queensland Development Code (QDC) Part MP 4.2 which addresses water savings targets in class 1 buildings and a new QDC Part MP4.3 to address alternative water sources in commercial buildings. These will commence on 1 January 2008. The QPW code compliments the QDC by providing for the approval of greywater treatment plants and setting the effluent quality criteria for greywater use. Water saving targets can now be achieved through effective utilisation of: • household rainwater tanks • communal rainwater tanks • greywater treatment plants • dual reticulation • stormwater reuse. The purpose of this guide is to assist councils, plumbers, builders and developers to understand the technical and regulatory requirements for on-site wastewater management systems, greywater use facilities and sub-meters. A full copy of the QPW code is available on the Department of Infrastructure and Planning website at www.dip.qld.gov.au/plumbing
