\ud83c\udf35 La R\u00e9gion Sud a connu, l\u2019an dernier, une s\u00e9cheresse historique, avec des d\u00e9ficits pluviom\u00e9triques de 30\u00a0% en hiver, 45\u00a0% au printemps et 84\u00a0% en \u00e9t\u00e9. Du jamais vu dans une r\u00e9gion qui a pourtant la culture de la pr\u00e9servation de la ressource en eau. Les cons\u00e9quences sont inqui\u00e9tantes pour l\u2019agriculture, la biodiversit\u00e9 ou la production d\u2019\u00e9nergie. <\/p>\n\n\n\n

\ud83d\udca6 En novembre 2022, le Conseil r\u00e9gional a sign\u00e9 avec le Gouvernement une premi\u00e8re exp\u00e9rimentation pour la r\u00e9utilisation des eaux us\u00e9es trait\u00e9es. Une technologie ma\u00eetris\u00e9e et largement utilis\u00e9e en Italie, en Espagne et surtout en Isra\u00ebl o\u00f9
90\u00a0% de ses eaux us\u00e9es sont retrait\u00e9es, mais encore balbutiante en France avec moins de 1\u00a0% (voir WE DEMAIN n\u00b0 39<\/a>). La R\u00e9gion Sud-Provence-Alpes-C\u00f4te d\u2019Azur fait \u00e0 peine mieux\u00a0: moins de 3\u00a0% d\u2019eaux trait\u00e9es \u00e0 la sortie des stations d\u2019\u00e9puration sont r\u00e9utilis\u00e9es, notamment pour les vergers dans les Alpilles. <\/p>\n\n\n\n

Des besoins multiples<\/strong><\/h2>\n\n\n\n

\ud83d\udca7 La r\u00e9gion se fi xe l\u2019objectif de 10\u00a0% d\u2019eaux trait\u00e9es r\u00e9utilis\u00e9es. En juin 2023, elle a vot\u00e9 une enveloppe de 250\u00a0000 euros pour que la Soci\u00e9t\u00e9 du canal de Provence, l\u2019Universit\u00e9 d\u2019Aix-Marseille et la Chambre r\u00e9gionale d\u2019agriculture identifient les besoins et utilisations possibles, comme la station d\u2019\u00e9puration de Maussane-les-Alpilles pour l\u2019arrosage des plantations d\u2019oliviers et d\u2019amandiers. <\/p>\n\n\n\n

\ud83c\udf0a \u00ab\u00a0Nous allons privil\u00e9gier les bassins d\u00e9ficitaires en eau, et les zones littorales o\u00f9 les stations rejettent les eaux trait\u00e9es dans la mer\u00a0\u00bb<\/em>, pr\u00e9cise B\u00e9n\u00e9dicte Martin, vice-pr\u00e9sidente de la R\u00e9gion en charge de l\u2019agriculture.<\/p>\n\n\n\n

\ud83c\udfd8\ufe0f \u00c0 c\u00f4t\u00e9 de l\u2019irrigation agricole, la r\u00e9utilisation des eaux us\u00e9es trait\u00e9es concernera les usages urbains, comme le nettoyage de rue, ou les espaces verts, le cycle de l\u2019eau industrielle, la r\u00e9alimentation des nappes phr\u00e9atiques et les retenues d\u2019eau pour la production de neige artificielle en montagne. Les premi\u00e8res aides r\u00e9gionales en appui des projets, avec le concours de financements europ\u00e9ens, sont attendues d\u00e8s 2024.<\/p>\n\n\n\n
