My hydro mining type operation was done in early spring here. There wasn’t as much mess as you might think but it’s not the sort of operation I’d do if I had neighbours close by or if there wasn’t a big runoff area on my own property. We had all the water at no cost because my [Censored] was overflowing owing to the record rains we had at that time. That rain also meant there was no mess to be seen within a day or so because it all just got washed away into the grass and trees below.

This was through earth that had been compacted with a few rocks in it. I really didn’t want to have to dig it all out as the path the pipe needed to follow was quite deep and a trench would have been risky to the structure of a very large buttress earth wall.

I’m going to need to run 15m of 16mm 4c+e under a concrete apron this year. The total run of the cable is just over 35m and it’s about 25mm in diameter, so it’s unwieldy and doesn’t like sharp turns. With this I think I’ll have to cut the slab for the trench as there is no way to drain water from the origin or destination; with one end against the house and the other at my brick workshop. My sparky mate suggested an overhead line but I’m not keen on the potential obstruction.
