Hi to all, I hope someone can offer some sage and sensible advice.
In our back garden, where we are planning an extension to the house as well as repaving the garden, we have a manhole.
We've lifted the lid on it a few times, and
1. It doesn't smell like a sewer
2. There's usually just a trickle of water at the bottom of it and
3 - at the bottom - it has a base that looks just like this one in the picture that helpfully corresponds on the main website (thanks - and we haven't figured out the photo upload).
4. The man hole is covering a chamber that is around 1.5-2m deep.
Here's the conundrum:
Of the contractors we've spoken to, some have said that 'moving it won't be a problem', where-as others have implied that 'moving it will be costly'.
(In the background, we *did* get a build-over agreement from Thames Water).
So - for those who have seen a manhole in a typical suburban garden in London with base like the one illustrated - what do you think it's *actually* draining? Is it merely collecting water that's been drained from the nearby roof, or is it more significant than that. Will moving it be a challenge, or will it be relatively cheap/straightforward?
Looking forward to any helpful thoughts that people have.
Many thanks!
