Land Drainage Costs

My trencher cuts a 5.5" trench and when backfilling with stone 50 ton goes nowhere! To use a digger with a bucket 5.5" wide would be impossible as the dipper arm/linkage will be much wider. I would say 10" would be around the narrowest so twice the amount of stone will be needed. Also when laying drains with a digger where there's little fall it will be extremely difficult maintaining the correct grade even if you have a laser!

This is what my late grandad started draining with as a young man. Those he laid are still good today.

I made one of these for small bits and repairing old drains. When laying plastic pipe it really needs bottom and side support to prevent squashing flat once backfilled.

I had one of them but my dad claimed it,I better get it back as it will end up in the scrap,I'm not sure he knows what its for.:)

You need to talk to tim or blondie at William morfoots they work nationwide and are seriously methodical about installing thousands of metres of drains bang on, drained with them for a year between jobs and it was a real eye opener on how accurate these drains would be laid and stoned up, there is absolutely no way you could put in long drain runs on flat ground with the constant fall and no back falls with a 360. The speed these chain trenchers travel is impressive and our best day on the fens near littleport we laid over 3000 metres with one trencher and two 8 ton shingle carts in 12 hours. On hard chalky ground we have been down to 600 metres when the digging is real hard. Have a look on there web site.

Looking at getting some proper land drains put into our grass paddocks, what sort of costs would I be looking at? Is it worked out per acre or per m?

Anyone know of Land drainage companies in the North West?

We use Gordon cork, was gpc land and water but renamed gpc74 to celebrate 40 years in business. can't recommend enough. An excellent team of workers that get the job done. They're based in the midlands but will travel.

We did 1400meters into an existing system a month ago, used a contractor with V bucket and he had a man with a laser level who laid pipes, we did most of it with 6"twin wall as it was fairly flat. He told me a trencher is fine for a new setup but if you want to tie in old drains a digger is better. We used 210ton of 40mm stone, it took 4 long days to do, cost about £2.25/m for stone, £2.75 for pipe and about £2.25 for the digger and man, I backfilled it all and we have a stone cart so that saved a bit, probably round it up to £10 a meter if you had to pay for it all.

How far apart was each pipe? £10/m over a field of 280 metres in length is £2800 the field is 85 metres wide so how many "Runs" would we be looking to put in?

Our field we just did the hollows, and a couple wet areas, trying to cut the water off as high as possible. I would say a lot depends on the way the field lies and the type of soil, the deeper you can put the drains down the bigger the draw of surface water they should have, if they need to be near the surface they will need to be closer together.

Should get this old converted Barth machine calibrated week after next, grade controlled with RTK using intellislope which is now owned by AgLeader and uses the Integra screen which I'm using anyway to control the drill/liquid fert/etc
I've about 15ac to drain before harvest and plan to go with 100mm pipe at 20m back filled with gravel to "plough" depth.

thats very impressive, but you are draining dry ground there, the kind of places im used to draining, with a digger you wouldnt be able to drive

That was just trying it in the ground last Feb, frost was just coming out, yes soft ground will be a problem as the limiting factor is traction not power, will more so depend on subsoil type. Doubt there are many diggers could bury pipe and backfill on grade at 2kph.
Any way early days will see how it goes.
