Les pr\u00e9-sableurs et 1-2 du syst\u00e8me de pr\u00e9traitement de la STEP GALINDO sont en mauvais \u00e9tat dans les zones des murs et des voies roulantes le long desquelles se d\u00e9placent les ponts dessableurs, emp\u00eachant un mouvement correct et conduisant parfois \u00e0 des d\u00e9raillements.<\/p>\n\n\n\n
Les vannes qui contr\u00f4lent le passage de l'eau vers et depuis le pr\u00e9- et le dessablage sont en fin de vie utile, pr\u00e9sentent un degr\u00e9 \u00e9lev\u00e9 de d\u00e9gradation d\u00fb \u00e0 l'oxydation avec perte de mati\u00e8re et ne garantissent pas l'\u00e9tanch\u00e9it\u00e9 n\u00e9cessaire.<\/p>\n\n\n\n
Le syst\u00e8me d'a\u00e9ration de pr\u00e9 et de dessablage (a\u00e9ration au moyen d'une turbine immerg\u00e9e) n'est pas efficace et il convient de le remplacer par une a\u00e9ration \u00e0 bulle \u00e9paisse qui a \u00e9t\u00e9 test\u00e9e avec succ\u00e8s dans le dessableur 1.<\/p>\n\n\n\n
