We live at no.21 in the picture attached.
We're planning a two story side extension to the property. As the picture shows, there are two points of "interest" at the side of the property.
I always knew there was one manhole cover on the drive that would need dealing with. It turns out that below it is two 12" pipes connecting from the left and bottom of the run to a main 16" pipe leading off to the right for surface water.
Having spoken to Scottish water, they provided the picture above and it flagged up there is more pipework on the property. The red one being a waste line with the same size of pipes connecting and another 16" leading out to the front of the property. It's not got a visible manhole cover but having dug down through the stones on the driveway, I came across a concrete plinth covering that area at the corner of the house. I'm assuming there's a manhole cover below that or the plinth is just covering the chamber that the waste runs through and it's an access point at least
So then, solutions? The width of the driveway is about 5m metres from the side of our property to the boundary at no19. I'm hoping to get a 3m ish wide extension on.
The house itself is about 6m deep and the front extension is another 3m so from front to back of that is 9m if those lengths help give rough ideas of the length of pipework requiring digging up.
Is it possible to move the two sets of pipe work to the boundary line?
How major a job is it? Less so if there was a dig for foundations anyway ?
And most importantly, roughly what costs am I looking at?
There's also a massive tree that'll be having to come away (visible just at the side of that second picture) and I'm wondering how badly the roots might have damaged any of the pipework if they're as long as the tree is tall.
Plot no.5 behind us are doing some extension work just now too. Having spoken to them, they seem quite ameable and having noted the manhole for waste on their property, I'm hoping we could connect at that point if we're moving the run of the red line diagonally to our boundary.
I guess another of the biggest issues would be the two lines coming from no.19 and how we cut them back at the boundary to T them in to any new pipework.
Any thoughts are appreciated...
