I AM A BIT STUCK ON A PIECE OF COURSEWORK WHAT ARE THE 4 DIFFERENT METHODS OF GAINING ACCESS TO UNDERGROUND DRAINS
I'm not sure - it's a long time since I was at college and, on the odd occasion when I was present (and sober) I don't recall ever being asked about four different ways of accessing a sewer!
Through a MH/IC/AC has to be the first and most obvious, and then by excavating to expose a line and breaking into the line would be second. From another pipeline could be a third but I can't think of a fourth....via a rodding eye or access gully, perhaps (asuming they count access by rods or cctv as true access)
What course is this? I can't remember this coming up on Confined Spaces.
