This paper presents and discusses the keys of success of a water reuse project for landscape irrigation and other urban uses in Bora Bora, French Polynesia. To better preserve public health and overcome all constraints and public opposition, a membrane tertiary treatment for the production of high-quality recycled water was implemented. Special attention was paid to the reliability of operation and economic viability of membrane treatment, as well as to active public participation with involvement of all stakeholders. The demand for the new recycled water steadily increased during the last two years with a wide diversification of urban uses, not only for irrigation, but also for cleaning, industrial and commercial uses and fire protection. Monetary and non-monetary benefits have been assessed and recognised. As a result of this successful project, new recycling projects are under development.
