Discharge into watercourse

[Donk]

Linked to my gabion topic , the site is quite narrow and we definitely don not have space to be 5m away from the building to build a soakaway per building regs.

I think the best option is to drain the roof and drive into the watercourse. I've checked with the EA and they say no permission required.

Is there an accepted method to terminate the drain into a watercourse ? don't really want the pipe to just poke out the side of the ditch!

thanks

Look under riparian ownership first.

you'll need to build a stone/concrete headwall where your discharge is there is a page on them on the main site but I'm struggling to find it and i know its there

found it scroll down to outfalls

thanks just what I was after.

Ourfalls are quite labour intensive with shuttering. On a "tiddly one " i'd place a base with starter bars and construct the walls with concrete filled sand bags.

an athalon precast headwall for a 350mm pipe is roughly £1000 +vat priced a load of them the other day

As this is a small one using 110mm pipe, we'll do some 'ground chippying' to shutter it. Probably use engineer bricks to face it.

Agree - no need to get carried away with it.
