Drainage - can you have 2 bottle gully's next to each other?

[perky416]

Hi guys.

I have a brick wall that seperates the back garden from the shared drive way.

One side of the wall there is a hopper (see picture attached) that catches the rainwater from the gutter down pipe. The bath, sink and kitchen sink are also fed into this.

The drain pipe runs under the wall and along the house.

Is it acceptable to fit a bottle gully immediately the other side of the wall? Second pic attached, right in the corner where the garden wall meets the house, where there the hole goes through the wall, where the last two paving blocks are, they would he replaced with the hopper for the new gully

It isnt clear in the pics, but the hole in the wall runs into the hopper the other side of the wall.

Both gullys will effectively be separated by the width of the wall.

Thanks

Put as many Gullies in as you like, the acid test is if the outgoing pipework can handle the expected flows!
