perforated drain pipe as a soakaway?

[Fred]

Hi,

I have seen some coils of perforated pipe in "been and queued" but
sister company Screwfix doesn't seem to stock it. Is it known by
another name?

The Pavingexpert web site says you can use it one of two ways:
holes-up to collect water from waterlogged ground to take elsewhere or
holes-down to dispose of water into the ground.

It's the latter I am interested in: could you lay a length of this in
a trench and use it as a soakaway?

TIA

I thought it was perforated all around, not checked what I have in the
shed.
I suspect Screwfix may not carry re physical size - surprised B&Q
carried it (must be a proper warehouse :-)

Ebay source:
From 80mm 25m at £18 plus delivery to larger sizes, it is a big bulky
item re courier.

Online source:
Drains Direct or similar do the same sort of price, but also carry the
UNperforated version for carrying water elsewhere.

Dig a trench of 1-in-200 fall, line with geotextile fabric, infill
with stones. If the area will see heavy traffic you need to use rigid
perforated pipe to stop it being crushed.

IME it's not worth a carrot in terms of draining ground, and certainly
useless as a soakaway, it does have an effect over large areas like farmers
feilds in reducing waterlogging, but far more effective would be 2 milk
crates wrapped in weed membrane and surrounded in 3/4 stone, with a gulley
into the top - a soakaway is just a holding tank, designed to hold flood
water until the surrounding ground can take it away naturally.

Perforated pipe should work fine into a drain.

Perforated pipe into a soakaway needs careful examination of the
ground.
The soakaway needs to be sized according to the rate at which water
can soakaway (volume) versus the area being drained. That means a test-
pit to see if digging down through (say) clay eventually finds a free
draining layer. Milk crates provide a lot of space, the old rubble pit
was more a pond if the area could not drain fast enough :-) The test
used to be dig down in February and watch (time) what happened to the
water.

Linear drainage will handle bulk surface water drainage on clay
somewhat better, Aco and other makes exist.

Wouldn't it depend how much you used? If you had a large coil running
up and across and down almost following the fences around your garden,
wouldn't that cover a big enough area to drain the rain from the roof
of the house?

wondering if anyone found out whether this 'one side' perforated pipe exists
because most I can see has all round perforations :-/!!??

I'm not seeing how it would help. Fine mesh always clogs. I don't recall the old clay pipe sections having that problem, no mesh & whatever enters can get washed out.

Clay pipe sections will tend to clog at the joints over time.

My property stands on London clay.

40 odd years ago I used 3" perforated plastic pipe (supplied in large
rolls which could be unrolled in the trench) buried 3' down with about
6" gravel on top. There were 2 pipes running from almost the front
boundary, diverting either side of the property, to a stream at the
bottom of the garden. Total distance 350+ yards. I also directed the
roof water into these pipes (building control said no because they would
clog up, building inspector said it was OK). For quite a few years I
would occasionally put a hose into a downpipe and view the water running
out at the stream. For the last few years it doesn't visibly run out
but neither is the ground boggy so the pipes are distributing water
along their length.

Twenty-odd years ago I helped my parents install some in France. Rather
than the pipe with small holes in, it was slitted perpendicular to its
length. It was normal sized (110mm), black, plastic pipe. From memory,
one side had slits covering around a quarter of its diameter, a few mm
wide, every 10mm or so.

A quick search has pulled up something similar, although not quite the same.

I've never been that convinced that soak aways in some soils ever work. Clay
can hold a certain amount of water, after that it is pointless it just
puddles and eventually floods.

Why are you replying to an 8 year old post ?. FFS READ the
original message including date.

If you want chapter and verse on drainage then go and look
