Abstract

L'invention concerne un procédé de nettoyage et d'entretien de systèmes de distribution d'eau potable, dont le débit est réduit à cause de l'augmentation de dépôts ou de sédiments sur la surface intérieure des conduites. On chauffe une solution de nettoyage acide et aqueuse (12) et on la fait circuler à travers la conduite (25) à traiter pendant une durée suffisante pour dissoudre et détacher les dépôts ou les sédiments, puis on évacue de ladite conduite (25) la solution utilisée contenant les dépôts et les sédiments dissous ou en suspension, ce qui permet d'obtenir une conduite nettoyée, dont le débit est amélioré. Il est également souhaitable de rincer les conduites avec de l'eau sous haute pression après le traitement, afin d'éliminer les dépôts et les sédiments qui n'auraient pas été extraits pendant la circulation et le rinçage de la solution de traitement (12).
