Plastic Pipes Draining Into A Concrete Pipe

mikefoxo

I have a stream running through one of the fields, most of it's along the boundary, but a section of it (100 yards?) cuts off part of the field from the rest. What I'd like to do is put down some conc' pipes and cover it. Problem is the surrounding land naturally drains into (about an acre in total). I'd also like to drain it too, probably at the same time. What I'm wondering is would the water drain properly into the conc' pipe? What with it not having any slits in it

The concrete pipes you need are ogee pipes. They just butt together but have no seal. Ive used them on 2 occasions here and both have been a success. Had to turn plastic pipes into them too and they seem to carry plenty water and land has dried since.
Dug a square trench with a 2ft bucket. Dropped in my 9inch conc pipes. Filled around them with 2inch hardcore to just over the top of the pipe. Dug my branch drains with a V bucket and filled with hardcore. Anywhere the branch drains enter the main drain (above the height of the 9" pipes preferably) id break a small hole in the nearest joint in the conc pipe downstream and turn the plastic pipe into it. Cover the inlet with stone and a plastic bag. Any water running in the hardcore will eventually work its way into the pipes at the joints.
Seemed to work for me anyway.

You could use the 6 meter lengths of perforated corri pipe,they are just as good as the concrete pipes and alot easier for working with..dont see many using concrete pipes anymore...

Would you need to cut & insert the 4" as per Foxy, or would the slits in the pipe be enough?

Cut a hole and let the pipe into the bigger one otherwise the small pipe will silt up.

Corrie pipe is a dream to work with compared to concrete.

Can you get a 4" bit for a cordless to core the holes?

100mm (or thereabouts) holesaw with pilot bit and adaptor will do the trick.

There's a good bit of water in the stream. We put down pipes a few years ago further along for a crossing. They're roughly 14" internal diameter and you need every bit of that in the winter. Do they even make plastic pipes that big??

Use 2 or 3 pipes together? JFC have a good selection of pipes.http://www.jfc.ie/CorriPipe&Fittings.html

You can get big corripipe but they aren't cheap.

Father tried that about 15 years ago. Suffice to say it has to be done again:rolleyes:

You say you have an acre on other side of stream and want to pipe the stream and make it all in one field. I'd use the jfc corrie pipe it goes up to 600mm/ nearly 2ft internal diameter. Then put drainage stone around and over pipe, if you wanted you could put drainage pipe as well beside the corrie pipe to increase flow. You could even bring drainage stone up to top of ground and forget about drainage pipe ( depending on length of acre/ stream). The flowing water in the stream should be able to keep the pipe clean of any silt or dirt.

Be careful you don't cause an absolute ****storm by piping a stream you have no legal right to pipe.
Before you even contemplate doing this work be absolutely sure you're not goin to fall foul the law.
This may or may not be the case. But you need to know!

It's not on any of the latest Dept. maps, or any other maps I've seen for that matter

Does anyone happen to know how much those 15" pipes cost? Priced conc' ones- €27.50 a pop!!!

Don't know about 15" but I got 12" ones last summer for €65. They were cheaper than buying 6 concrete pipes by around €15-20 as far as I can remember.

Get the Corrie pipe easy to work with, order with slits and it's pretty unbreakable, can be cut with a handsaw.
If you go concrete they are a nuisence to lay, break easy and take a lot more time. You can carry a 20ft corrie under your arm!
