Digging/trenching new water system

[RJ1]

Evening

I'm after your thoughts on the best way to go about this.

Totally new water system required, some 3000m in total. I'm waiting on site visit from a contractor with a trencher type machine and I've got another wanting the job digging it in.

Generally over shale, with some clay in parts and a fair few large stones below ground i would imagine.

Have any of you experience with doing this and likely cost effectiveness of these methods/ any problems with either?

Thanks

Watching with interest as have the same to do here.

Mole it

Will you get it 750mm minimum depth with a trencher through that terrain

 

[TomB]

All of ours moled (at sometimes questionable depth.) if done properly with decent kit you can do a decent job quickly. Spent half a day in nz helping with a d6 moling in 50mm pipe on a dairy. Trenching will be fairly slow and expensive, digging unthinkable? Might be worth talking to a drainage contractor for a trenching price?

 

[I thats it]

Here we just rolled the pipe out on the top along fence lines, just dug it in across gateways

My cousin moled 750m of 50mm water pipe for me with his bruff tg3, wouldnt do it any other way.
Where abouts are you @RJ1

That looks impressive!

About 20 minutes from Welshpool on the road to Mallwyd/Brigands Inn. Does he contract with that?

Sent you a pm

My neighbour moled in a lot of water pipe, but we have flints and the pipe got cut to b*ggery.

Trencher best bet as long as you know where drains are at and can avoid. If there's a lot of stones will need to dig, 8 tonne machine ideal for this having enough muscle to pull boulders out.
Just done 450 m with a wheeled digger, could dig 400mm wide trench to 850mm depth at 15m per hour by myself. Terrain very mixed from sand to bog to gravel with large boulders.

As you are over shale and stoney either lay it on the surface and use black pipe or dig it in so you can completley surround it in cable sand or it will be full of holes in a year or two. I would lay it on the surface to start with as digging and sand will cost a fortune and wont guarantee it's not full of holes in 10 years time on shale.

we put a main round, on surface, when we wish to reseed, dig that length in. Digging it in, 30ins, if any drains found, we can re connect. Found with mole plough, can be uneven depth, and have 'caught' pipes, before, where mole has lifted when meeting a hard spot. Digging also allows you to see soil structure, over an extended length, which can be interesting.

We use a firm with one of them on a 20ton 360. Just the job, very quick. 63mm ring main with 32mm spurs

 

[teslacoils]

I'm putting 2000m of 62mm pipe in. We dug it the first km. Will trench it the next. 1m deep. Clay and sand. No stones.

Is that a vibrating mole?

 

[RJ1]

Thanks to everyone for their suggestions. Will have a think and a chat re the different methods.

Does anyone have an idea of the cost per metre of the different methods?

 

[Beef farmer]

£1 per meter for 63mm moled with 20ton 360. He digs the joints in that money too.

Shame you're a bit far! That's a good price of the job's done well.
