Alternative to soakaway

[Oceanjules]

Hi,

 

looking for some input here please. What would be the best solution to have a rainwater outfall without digging up a driveway? 
 

We recently had an extension done and this is the last one prior to completion. The current downpipe runs to the flower bed and the BCO made a comment about it. 
 

I will also get back in contact with the architect to ask for solutions. I just need to know the options are as I’m stressing about it. 
 

Thank you.

A gulley drain, aco, leading into a drain outlet? You might even be able to do a french drain in the flowerbed or something, if you can’t move the soakaway to the lawn.
 

It’s hard to know without the plan and the planning implications. 
 

I wouldn’t stress about it, it’s not a major issue and it’s rarely even checked from what I can tell.

I have this question as an issue I've been kicking down the road. Building Regulations says either into a drain (by whatever means) or soakaway. My first BCO was happy with a french drain out onto the sloping ground in front of the house (but this wasn't followed up in writing). Now I'm being asked to either have it into drain or soakaway. A customer recently had an extension done to their house and they used a drainage channel to get to the foul drain. I might do the same if I can.

The foul drain might be an issue, it’s only for circumstances which mean you absolutely can’t use a soakaway and you absolutely need permission to do this. I’d avoid it as being flooded with foul water isn’t a joke! Might need a trapped gulley if so?

In my instance, it's an existing building that had a combined system before we began works and due to the terrain, being on a steep slope and where the down pipes are located, there is no choice other than to do it because the existing underground drains are in the way so we can't dig any new ones. And yes, will absolutely be into a trapped gulley

Going back to the OP's question. Can you clarify, when referring to a downpipe going to a flower bed - is that an existing one or the one off the new extension? Not sure why you would need to dig up a driveway if there is access to a soft area such as a flowerbed.

[Oceanjules]

No, it’s not an existing one. There is an existing one on the side to catch the water from the side of the side and this pipe is for the bit of flat roof from the front. We extended the pipe to the middle of the flower bed so the water won’t end up next to the garage. The BCO wants a solution for it as it must have a rainfall outlet. Customer doesn’t want to dig up the newly installed driveway.
