Alternative Water Supplies HomeLiving HereEngineering ServicesUtility ServicesWaterAlternative Water Supplies Letterbox signs are available from Council for households with an alternative water supply such as a bore, rainwater storage, grey water reuse or dam storage. Residents who have an alternative water supply source are not subject to water restrictions when using their alternate supply. Council strongly encourages applicable households to display a certified sign to indicate the use of an alternative water supply. This enables Council’s local laws officers to quickly recognise properties with an alternative water supply during water restriction patrols and when investigating reported breaches. Alternative water use signs will be issued free of charge to approved residences. To apply for a sign, please complete a notification of alternative water supply application. The application is available at all Council Customer Contact Centres. You can also contact Council on 1300 268 624 and a form can be posted or emailed to you.
