    Piping a small stream

    I have a small stream which runs along the edge of my boundry wall. I think it's supposed to be a flood stream but I haven't seen any water in it for the last year.
    I don't want to fill it in, just in case we do have a flood.
    I want to pipe it, then backfill over the pipe.
    Maybe you guys can correct me if I'm wrong but I believe I can get some cheap concrete pipes specially made for this purpose. They not like the dense conrete pipes used for sewers and they don't have a joint, they just butt up to each other.
    I need them to be 70 or 80 cm Diameter and each about one meter long.
    Has anybody any Idea of the price.

    I'll only be back in Thailand in about three weeks time, but I wanted to get things organized before hand.

    Hope you can help.

    I had to lay some concrete pipes to get the rain water past our house.
    They come in several sizes, sorry cannot remember the price of the size you want.
    I used the small 9 inch ones [at] 200 baht for a 2 metre length

    Just butt them up and "seal" with clay or mortar

    They sound like the one's I need but I need much larger diameter.
    Thanks for you help.

    Perhaps you are referring to the thin concrete sections used for septic and water tanks. They are used vertically, but, I suppose they would suffice for a cheap drain pipe laid on their side, if there are NO loads on the covering soil ie: cars, trucks, buffalo, elephants etc.

    Be careful that this stream is not shown on the land title deed as if it is it is illegal to fill it in.

    You would then have to apply to the local council, (and to be allowed to change its natural flow course) and to replace it with storm water pipes may be possible but has to be approved by the council civil engineers.

    Available all over Thailand in varying sizes.

    Take care here. Will depend on where you are located. Where I live no one would notice.

    Thanks! all for your input.
    The stream is not on the Title deed and I also asked the local headman, he said no problem to pipe it.
    The steam actualy runs along the south edge of my land. I have just had a new boundry wall built. But as you can see from the photos the stream trench is making it so that the wall footings and piles are exposed, also the top of the trench is about two meters wide which is also unsightly. If I pipe the stream and then backfill then I can put in some plants which will make the garden look much better.
    I have no intention at present to have Buffalo's or Elephants, so the pipe strength isn't that important.

    You are right. Needs to have culvert to avoid damage to the wall footings. Diameter could be smaller than the 80cms you suggest but depends on expected amount of water run off. Best way to assess would be to look at the size of the stream bed entering your property.
    Whenever you find yourself on the side of the majority, it is time to pause and reflect.

    ^ Yep pipe diameter is all important and to move all the stormwater onwards and away from your property.

    Do yourself a favour and speak to your neghbour before directing the flow onto his/her land or, and as by law all storm water drains must be directed back to the common road.

    Also and based upon your pics it looks to me that the construction guy just dug out that area and to put in the wall foundations.

    They aren't strong enough plus too short for use on something like this.

    These are the concrete rings you want here (Build your own Thai road drainage).

    why do you need to hide it? you could use U-profile concrete sections to run the possible water flow; these would also protect the wall footings

    Much easier to clean the debris out and easier to stop from becoming mosquito central also.

    Thanks! All.
    Great input. Dirtydog! you got it spot on. The pipe in your link are exactly what I want. (any idea how much they are)?.
    It's difficult to tell from the two photos, so I'll post some more.
    Actually the stream at the other end goes through a pipe under the road and then into a big lake.
    I don't want to put concrete U channel in because like I said, I've only ever seen just a trickle of water in the stream, if it was flowing with water then I would leave it open and make it more decorative.
    Anyway here are some more pics.

    Thanks! If I can get them for around that price it will be great. I'll be back in Thailand in two weeks, so I can get that job out of the way then. Cheers!

    DD, Do you have any idea were I can get these pipes. Between Pattaya and Rayong?. I don't need the full address, Just a road name will do. It may save me some time driving around. Cheers.

    Sukhumvit Road, heading out of Pattaya either way you will find builders yards with them in, between Rayong and Pattaya yesterday I saw a place, if you head down Sukhumvit to Sattahip, at the lights for Ban Chang about 10km before Sattahip take the left, around 2km down there on the left they sell them, but any of the tatty builders with big yards will have them.

    There is a builders yard on the road to Mataphut from Highway 36, but he is a bit expensive, try and shop closer to Pattaya and Sattahip, some of the merchants in Rayong think every farang here is rich with petrodollars.

    Well! Thanks to the info you guys gave me I managed to get my stream piped and back filled. I got ripped off with some of the materials, pipes,sand,cement, backfill. But the total cost still came out at less than half the price the builder quoted.
    Plus using a spade after such a long time did wonders for the old beer belly.

    Here's some pic's enjoy!

    A success indeed. Looks well done. Now you only have to locate a very long pipe cleaner to remove all the debris when it clogs up.

    A few manhole covers spaced along the length of the culvert may be the answer.
