@josh_pollard: Clearing rubble out of a drain casuing multiple manholes to back up. look see with camera initially indicated a collapse on the further inspection proved to be a manhole hidden under the bike rack, exposed and dug out rubble from chamber and jetted lines. carried out CCTV survey to prove asset condition, this proved multiple breaks and a redundant line that suspected vermin and silt we’re travelling through used @FerncoUK NON no return valve to resolve this problem #rats#dalrod#clearingblockages#fyp#oddlysatisfying
