The term AMUNA is derived from an ancient rainwater harvesting technique.
The application of delaying stormwater and rainwater runoff is as prevalent today as it was back then—modern techniques such as on-site retention and on-site detention systems are used to ensure the development contributes to its environmental obligations and assists in alleviating pressure on Council’s stormwater networks.
