Rainwater tanks are not mandatory for every household in NSW, but they are required in certain circumstances. If you are building a new home, adding an extension, or undertaking major renovations, you may need to comply with BASIX (the Building Sustainability Index). BASIX sets sustainability targets for energy and water, and installing a rainwater tank is often the most practical and cost-effective way to meet these requirements. These BASIX rainwater tank requirements are a key part of ensuring new homes and developments achieve long-term water savings and improved sustainability.
Local councils can also set their own rules, particularly in areas prone to drought or water restrictions. For example, some councils encourage or mandate rainwater tank regulations in NSW for new developments to reduce demand on the mains supply and to support more sustainable water use across communities.
It’s also important to note that if rainwater is used for drinking or cooking in premises that serve the public or employees, the system must comply with the NSW Public Health Act 2010 and follow the NSW Private Water Supply Guidelines. This ensures the water consistently meets strict health and safety standards while supporting BASIX compliance.
