Cheap drainage solution!?

[Maf]

Can someone suggest a cost effective way of piping storm water 100m at about 110mm diameter (no need for slots)

thanks

6m length pipes interlocked bedded in 100 mm of 10mm gravel at 1:60 fall
about £300 for the pipes
labour/ shingle/ trenches/ extra

Rolls of wavin coil (perforated) drainage would be cheaper, depends on the spec for the job.

6m pipes ? Like the Marley 110mm underground stuff... Sure that would be more than £300?

It's to take the flow of an intermittent spring that currently flows in a small ravine. I want to fill the ravine to level the land.

we have done this, but with a spring/stream that runs all year.

first way we did it was with big 600mm concrete pipe we had left over, but to buy new your talking a lot

then we've used proper 450mm plastic again for a regular stream/ditch that was to replace a piece of 300mm gas pipe that was to small for when it was in flow

100m roll of 4" wavin coil should set you back about 1/metre at retail, line it with pea gravel or clean stone.

100m roll of 6" wavin coil about £1.80/m depending on supplier try Mc Carther/burdens or local BM or agricultural merchants always carry it at a good price

intermittent spring

read "raging torrent" when it rains hard????

110 mm pipe is probably not suitable for a watercourse, i see 68mm downpipes overflow when it rains hard ,
maybe a bigger bore of pipe?
you really need some specialist local advice maf
all the best
