Garden Log Cabin Plumbing

[Mcknze21]

Hi All,

As my wife is a hairdressing we are looking to build a log cabin in the garden for her to carry out her work.

The issue I have is with the waste and was looking for ideas/advice.

We can get cold water supply & electricity to it no problem however as the garden is on a slight slope I’m not sure the best/easiest/cheapest/right way to do this?

I kinda know already that I will need lift floors in my house I think as I can’t go in to the rainwater gutter pipe and it need be waste wipe wouldn’t it?

There will be no toilet. This just be sink waste from hair washing.

What’s the soil like is it clay below or decent ?

 

[Mcknze21]

I think it’s soil. May be quite compact but definitely not clay anyway

 

[Mcknze21]

I might have to confirm that before proceeding so thanks for that for a start as that’s exactly where I am at. Looking for advice for both.

There was me thinking my main issue was how to get the waste away.

Depending on ground you might be able to use a soak away (also depending on what chemicals she uses ) if not best run a 2” waste to the stack / drain

The bottom of garden seems to be maybe approx 1-2 ft lower than the house. So maybe mean it would need run uphill? This is my issue. Would I need a pump?

The waste stack is on the opposite side of the house. I’m looking place it where the decking is. Then maybe run up side of fence but then the waste stack is on opposite side of house.

Is there any manholes in the street eg with the tree ?

 

[Mcknze21]

Not that I know about to be honest

 

[Mcknze21]

Where would I be able to find out about manholes as this most likely make things easier wouldn't it?

As for if I was to connect in to my waste stack, what gradient is deemed acceptable? I take it nothing uphill is acceptable? What about a use of a pump?

Most pumps would need to fall around 10mm per metre over that distance..

So even with a pump I'd require a decline? Sorry if I've misunderstood!

 

[Mcknze21]

I'm thinking about 40mm pipe running from cabin to waste stack but it's just the path that is my issue, trying to give it a decline.

No not all need a fall. Look at Lifting stations or pumping stations,

OK I will. Thanks!

I am just thinking that the back wash will be at least a metre in height so I could use that and not necessarily go underground. I could run fromthat back to house and that give me my decline maybe (I hope!) Just means building some sort enclosure for it to run alongside fence.

Any more suggestions welcome folks!
