Drainage question

[Ali]

This trench runs downhill right along my fence line. Its there because the fence was set on the neighbours higher ground which looked untidy.

I’d appreciate opinions on running the rainwater from a couple of largeish sheds into this please. I’d direct water into the drain at the end but I think most of it would soak away by then in anything but the most torrential rain.

The bottom is concrete but the back (below the gravel boards) is soil.

Thanks.

Run a test for an hour or two, flowing water from a hose, and see where it goes/what gets wet.

Good plan, I’ll do that.

no dont do it

its a boundary wall / line not worth the hassle in running water and erroding the surface

if your going to do it run a pipe direct to the drain and join in but take note what goes in via a tee so the flow is forced through the pipe pulling on the other

in practice you can join 2 roofs with alot of water into rainwater pipe but in heavy rain it can overflow your gutters
upgrading to a bigger pipe is the better aproach or 2 rainwater pipes

Always remember, **** runs downhill

It’s an option but without regular running water, won’t it silt up?

If there is a whiff of your incorrectly diverted rain water soaking through or running into the neighbours no matter how good friends you may be , if it's going to cost them money to rectify it or if they can say it has caused them to lose value on their property as a result and they can't sell if for market value .. stand by to be sued. As said pipe it correctly , put in a couple of rodding points too there is nothing more annoying to find in old age you are tryinbg to rod out 45 mtrs of clogged with roof rubbish & a plastic bag 100 mm UG rainwater pipe .
Piping it will also prevent you discovering just how unwise it was to run it as you've suggested when it also affects your own garden .


I've put in 150 mtrs of 100 mm perforated land drain in four 35 mtr runs some 16 yrs ago , back filled the trenches with 300 mm of bark pulp & chippings , then laid on a porous membrane & refilled trenches , heavily salting them with more bark and fibre as I back filled with the local earth . . The land drain system is a good 600 mm lower than next doors garden .. luckily I took photos which show it.
Last year after getting in a so called gardener to cut her front & back grassed areas the old gal next door to me complained that the gardener said t6here was a three springs running from my property across her lawn ( read terrible grass patch ) .
I explained the measures I'd taken to get land drainage out the back of the garden to wards the rise area of water course as I too had discovered a few weeks after we came here that I couldn't dig down much more than a spades depth without the holes filing with water.

I've also had 280 square feet of veg & flower beds 4 foot wide 900 mm high raised brick built on cast concrete drainable foundations so I an grow my own veg etc. & filled them with a good drainable non soil growth medium

I think you’re right, I might be able to make it work if I formed a proper concrete channel but that would be a fiddly job. All too close to the neighbours.

Thanks for the advice.
