The rehabilitation work included chemical sealing of manholes and sewer lines, structural spot repairs, and extensive manhole upgrades... All joints within the mainline sewer were pressure tested and sealed, using a urethane chemical grout. All lateral service mouth connections were pressure tested and sealed. Several areas of the sewer system required inline reaming to remove root infestations, protruding lateral connections and calcium deposits prior to chemical grouting.

CONT

Robot de fraisage [...] Cette unité permet de préparer des opérations de réhabilitation [de réseau d'égout] avec des moyens matériels optimisés pour apporter simplicité, souplesse et rapidité de mise en œuvre en exploitation. Ces caractéristiques permettent à une équipe très réduite de mettre en œuvre ce système, en générant un minimum de nuisance pour l'environnement. Cet outil de fraisage est indispensable pour : - supprimer les dépôts, - brosser la surface du tuyau, - éliminer les obstacles (branchement pénétrant, racines).

CONT

On a constaté dans l'ensemble une mauvaise qualité de l'assainissement : - Défauts de conception : pente insuffisante provoquant l'obstruction dès le moindre désordre (joint déboîté, branchement pénétrant, flache), pente irrégulière, parfois même inversée (un cas), surprofondeur des boîtes de branchement (surcoût inutile, rupture hydraulique), branchements inversés par rapport à l'écoulement du collecteur, regards surnuméraires (pouvant être remplacés par des culottes).
