Adding hopper drain to garden

[Cellophaneskies]

Hi everyone

I only have a hopper/square drain cover with grille at the front of my house where a gutter discharges. This means when I need to pour out water at the back of the house I have to walk to the front to discharge it down the drain.

I’d like to add a hopper to the back garden so I can pour things away and - bonus if possible - add a forge downpipe above it to give rainwater another route into the ground drain.

I could dig down, add a hopper and then add pipe all the way along the house to the front. And then drill into the side of the existing drain (don’t know right terminology) so water goes into the normal drainage system.

I’m just thinking about this conceptually right now, is this fine, do I need permissions or to think of regs etc? All I’m doing really is adding a pipe extension to discharge into an existing hopper/drain. Or is this silly fantasy?

Thanks

You might find it easier to connect into an exsisting inspection chamber if you have one.

What exactly do you want to 'pour away'?

Bear in mind any drainage run needs a steady gradient in the direction of flow, and needs joining into the existing system at a suitable depth to achieve the required fall, (Gradient), along the run.

If this is achievable, you will need to couple into the existing drainage run, at a convenient point, using a junction. Breaking into the side of an existing gully, (unless it is the type with a built in connection for an incoming pipe), is not likely to end well, you'll probably destroy the gully before you get the size of hole you need.

Pour away waste water. Buckets from mopping floor, bowls of water from cleaning.. just general water.

sounds like it’s more hassle than it is worth though!

It will be, just for that! Could make a lot of trips carrying a bucket in the time it'll take you to dig the trench, lay the drain and reinstate! Plants arent fussy on what water they get, provided no bleach etc in it, give your garden a drink?
