Fluid transfer operation, Waterloo Waste Treatment Plant

3 photos. All day today, there have been tractors pulling fluid tanks going in and out of the treatment plant on University. They go straight onto and off of the expressway, aided by a WRPS SUV using its lights to block traffic when needed. Not sure if the lane closure is related but there is a small crew watching things from there. I think it is to help control traffic approaching the place tractors are crossing University frequently. The white sign is about an unrelated closure of Bridge Street.
