Twin wall pipe will work fine, lay the pipe level and step it so the slurry drops off a edge, the slurry dropping will displace slurry and keep it all moving, it will always be half full. Got 200m of 450mm working fine using the same principle. Longest run being 50m
Been doing fag packet sums each drop is going to cost £1000-1500 plus labour (using concrete chambers) plus the road crossing, still haven't had a price for that, but it's a minimum of a 3 day road closure with ambron doing all the paperwork (no they won't do it on the qt over a weekend) Pumping the slurry through a 5 or 6 inch main could probably get that moled under the road much cheaper than a full road closure , and the rest put in cheaper too.
