Rainwater tanks are mandatory in South Australia for most new homes and significant extensions. The South Australian Government requires new dwellings, as well as additions over 50m², to include a rainwater tank plumbed into the building. This is part of the state’s commitment to water efficiency and sustainability, ensuring households reduce reliance on mains water where possible.
The minimum capacity requirement is a 1,000-litre tank, although many homeowners choose larger systems to maximise water savings. The rainwater tank must be connected to at least one toilet, water heater, or laundry cold-water outlet to meet building regulations. Further details are outlined on the South Australian Government website.
Local councils may also have additional conditions, particularly in areas where drought and water security are ongoing concerns. While the rainwater tank regulations in South Australia set a minimum standard, many homeowners and businesses in South Australia opt for larger tanks to support gardens, stock, or full household use.
