Guest house in garden, cost of sewer and water pipes?

snifflette

We want to put a log cabin at the end of the garden with a small shower room. Can someone give me a rough idea of how much it would cost for the sewer pipe in particular? Garden is about 90 feet. I just need to know if it's even worth pursuing. £1000? £10,000k?

Are you just talking about shower waste, not foul waste from a WC?.
The garden may be 90 feet long, but how long will the drain need to be to where it connects into the existing house drainage system (not sewer)?

Hoping for a toilet too. There is a downstairs loo at the back of the house but other than that, I don't know where the pipe network is.

After the problems in some London areas with these "Cabins" being let as accomodation there's a sceptisism among planners about it. The pipework would have to be laid to building regs, permission sought to connect to main sewer and then a building inspector to sign off the work. Planning permission per see is generally not required as long as the council are happy it's for a family member, though they do get concerned if it looks like you might then flog it off. Also, as you have mains services, you could be subject to council tax on the property. Just one link as it's shorter than some others and less 'Legalese'. :cool:

Then to state the obvious, you need to find out. Not difficult to look for manhole covers on the property. Where is your soil stack?
With a WC it becomes a much bigger task, as you'll be laying 100mm pipes to the existing drains.

We haven't moved in yet, and I was just asking for a ball park figure

If an outbuilding contains any 'primary accommodation', i.e. bedroom, bathroom, shower etc, then in the vast majority of cases it will require planning permission. Permitted development rights only exist for ancillary outbuildings - and primary accommodation like that is not regarded as ancillary (many appeal decisions confirm that approach). So I'd be wary about putting a shower in it, if you're not intending to apply for planning permission.

We have every intention of applying for planning permission if necessary. My question was about putting a sewer pipe through the garden!!

We have a brick built extension at the end of our garden which includes a shower room and loo. It's around 15 metres from the back of the house. However, because it's at a lower level than the house we also needed a pump to get the waste up to the sewer. It's like a big barrel that fills up with the waste and water and then when it gets to a certain level a pump pushes it up to the sewer.

So bear that in mind if your plot slopes the wrong way!

I remember the pump and barrel cost around £1200, but would need to check the quotes for the other stuff (digging out for the pipes and water feed - extra junction off the pipe that feeds the outside tap).

Thank you. Do you remember roughly how much the rest cost? I'd rather know if it's worth perusing before getting lots of people in for quotes. So wondering if it's a few£1000 or tens of £1000s

There can be no ball park figure. The cost would depend entirely on where the existing drainage was situated. You need to know the exact position of the existing drains. This is not difficult to establish, as you can normally see the inspection chamber lids..
