Piping a ditch

[Andrew]

Would like to pipe a length of ditch, about 360ft long. It’s next to a building and has 4 8” downpipes feeding into it (about 18,000 sq ft). So what’s the best / cheapest way to do it?
A big (4ft?) pipe so it takes longer to block? Or a small one so the water moves through quick? We’re right on top of a hill and it has to go nearly a mile before the fall increases.

Once you price up a 4ft pipe you might decide you actually quiet like your open ditch! Given the limited fall, what ever size it might be a worthwhile investment to install some inspection chambers at intervals to provide easy access for rods/jetting

Not sure it will be cost effective.

As above, they might be pricey. I don't know but what do concrete gullies price up like compared? Easier to clean than a ditch.

Yeah know it’s going to be expensive which is why I asked. We’d like to tin the side of the shed, but then no access to clean the ditch out or cut the hedge. Thinking it may be cheaper to rollershutter the side of the shed at this rate.

Got to ask why was the shed built so close to ditch ?

 

[Doing it for the kids]

next time shed is empty just flail up and dig out well?

It was the only suitable place allowing for fire breaks

That’s what we do, but wanted to tin the side of the shed.

Get some second artic hand curtain sides.
You could always get someone with some big secateurs or electric hedgecutter to do the bit behind the shed and just drive a minidigger up the channel every few years.
Pipes block up.

6" perforated plastic pipe, either in coils or 20' lengths with a good covering of 20mm gravel and inspection chambers where roof water tips into..
Neighbour used 12" pipe to do a similar job but it collected some spring water as well..

Maybe do this to the ditch (don't know the english term).

That way you can get a bit wider edge and get there with a mini digger.

Steel piling, water vole fans love it!

Motorway barrier cut in half, then pushed in with a digger?

Big dia. pipe got to be the way to go if possible. Future proof it.
Worth trying FP McCann or similar? ...they may have a quantity of pipes now and again that have been rejected/ not passed QC for big civil jobs? ... hair line cracks or chips ect but would be perfectly good for your intended use imo. Good saving if you can get them.

If you do the sums, 18 inch pipe will cope (gives you a 25% freeboard). Belt and braces would be 18" twinwall bedded and covered in clean stone.
In the real world 12" twinwall and stone would be more than enough.

No good putting this right next to the hedge roots.

Sorry, when I've blown picture up properly it does look a bit close for perforated pipe.
