Hey Guys, on our new build in the rain yesterday i realised we will need a drain system down the side of the house. We are in the sticks so we cannot connect it to another larger drainage system. The only thing we can do is direct the drain towards our neighbour's land, and then let the water run across his land

the neighbour's land is a small strip that is between us and a lake, and he will never build on this land, and does not use it, he has just retained it to stop people building out into his lake

we are not getting on too well with the neighbour at present, and are a little worried what his reaction would be (we cannot talk to him though as relations have broken down)

what i want to know about is the law. if we run a underground drain towards his land, and then release the water as it starts to slope away to the lake, and the water then runs across his land and into the lake, would he be able to make us remove the drain?

Why not run a perforated land drain along the side of the boundary and let the water dissipate at a lower level. Whether it runs into his side or your side is natures law.

Certainly don't directly lead the drain to a direction that empties on his land.

Although the water isn't actually yours it still would be a bit rude.

thanks for adice eyecatcher

as we are beside a lake, the land slopes from back to front, and all the water runs towards the lake anyway. i dont think we can get the water to run naturally in any other direction, apart from towards his 2 metre strip of land besides the lake

we would release the water a few metres before his land, but we would be aware that the water is then going to flow across his land and into the lake. relations are that bad that i know he will go mad, but the water needs to be drained somewhere

On the inside of your boundary put in a septic tank about 2 mtrs deep....do not seal the bottom and run your water into this...it will dissipate underground and any flood rain will be regarded as run off water (natural occurring) ....You cant stop natural flow. i have put 2 of these in and they work well...

Other than that dig a large hole and put in 4 mtrs of 8mm gravel.....drain to this, flood rain water will overflow it but thats natural runoff.....

I assume by now you know the direction the water "normally" takes. Dig a small ditch and put in a French Drain,

Then near the end of your property dig a 1m x1m x1m deep hole and fill it with rubble (Soak away). Then having done your best you will have to let nature take its course:-)

How deep is the water table? Ie. how much lower is the lake from your property. If not so deep you could dig all the way down to the water table and then fill with rubble that way the water will find its own way beneath your neighbor's 2m strip.

If the strip is only 2m to the lake and if the soil is not Bangkok Clay, you could dig down and run a PVC pipe under the 2m. Like so..

You are in a trench on your side and if you angle the pipe slightly down towards the lake

I would instal the PVC pipe at the same time as you "drill the hole" from inside the PVC pipe. High pressure washer if you have one is good for this!

Add some drains and piping to catch your water before it runs off, then at the lowest point, make a soakaway out of some large diameter concrete pipe sections. Remarkably effective.
