Drainage and Groundworks

With the scaffolding down and gas, electric and water all routed into the house (we’ll conveniently ignore BT for now) the outside was pretty much ready for the next few external jobs – preparing for the garage and getting the drains laid.

In theory we could have started some of this work quite a bit sooner but work on the garage couldn’t start until the shipping container we were using as a site office and storage was removed. It was quite handy having it as it kept the external trades out of the house and the inside of the house as clutter-free as possible. And less ‘stuff’ visible to unwanted night-time visitors.

Rainwater

Each of the downspouts from the gutters feeds into one of two soakaways. These are just holes in the garden that are filled with stones (then recovered) which allow the water to ‘soak away’! With the land being so sandy we don’t have a drainage issue and these work pretty well.

 Sewerage

In total we have 6 soil pipes exiting the house to feed into the main sewer, with four on one side of the house and two on the other side. There is one for each of the three bathrooms, two for the downstairs cloak-room (I know – see the blog entry about the issue with how the ducts were originally laid into the slab) and one from the kitchen. The utility room feeds into the one from the second en-suite. On each side of the house they merge into each other and then route off towards the main sewer. At each point where there is a change in direction we need a man-hole to allow for access. As ugly as they are there isn’t a lot we can do about this so the only thing was to ensure that they would be sited in the grass and not in the path around the house. I’ll try and get some of the covers that allow grass to be grown in them if I can.

Fortunately, I think, the main sewer runs through our rear garden so connecting to it should be pretty straight forward, assuming we can find it! Each of our two neighbours ‘knew’ where it was, although they hadn’t actually seen it, and the plan supplied by United Utilities was at about the level of detail my 9-year-old niece could provide. Aside from it’s general location the other challenge was that, based on where the neighbours said it was, it must be DEEP! At a guess around 4-8m deep. Oh joy

A morning with a big digger didn’t uncover anything so we resorted to UU’s sketch. And then we found it! We should employ more 9-year-olds I think. Or is that not the Right Thing To Do these days? The pipe is about 1.3 m down but only around 180mm in diameter – for some reason I was expecting it to be much bigger. So we had a big hole, an exposed main sewer and a number of our soil pipes ready to feed into it. Just need to get Building Control to approve it all now.

Building Control

The Building Control Office (BCO), Bill, arrived to sign-off the drains and was really happy with what he saw – all good. The only fly in the ointment was that BC don’t sign off the connection to the main sewer as that’s under the control of the utility company. And you can’t just connect to the sewer, you need permission. We didn’t have permission!!!! Now, this is something I should have picked up on a year ago when we got the water connection but as the forms asked whether we were connecting to the mains sewer (yes) and there was no resulting instruction to do anything I’d struck it off my list of things to think about. The groundworkers had a moan (it was all my fault…) but I did point out that they’d connected to main sewers hundreds of time before, knew we were connecting to a main sewer, hadn’t asked whether we had permission (apparently they didn’t know!), hadn’t organised for UU to come and inspect the works and also would have connected it up if the BCO hadn’t said anything.

I made a few quick calls, filled in the forms, pleaded for a quick approval and got it all sorted within about a week. Having said that we are still yet to make the connection though as UU need at least 5 days to inspect the work before the hole is covered up and the guys were due off site the following day. They need to come back in a few weeks anyway so it’ll be done then.

Levelling and the Patio

The site slopes from front to back, not massively but ‘plenty’. As far as the font of the plot is concerned the main challenge is to find a way to go from the gate to the front door, while still keeping as level a driveway as possible, bearing in mind there is about 1.3m height difference over around 11m. We decided that the best way would be to build a small wall in front of the house with a path between it and the house itself. The driveway would come to just below the top of the wall. We’re still to work out the exact details but as we’re just about to build the garage we do need to know where the driveway level will be so that we can lay the garage slab. I think we know…

As part of the works we reshaped part of the plot to make it a little more level and dragged top-soil and sand around to achieve this. It does look much better now but we still have work to do, which will be done when the sewer is connected. We’ve also laid MOT Type 1 stone around the front, one side and back of the house onto which a path and the patio will be laid. I’m hoping the patio won’t be too big but it does look sizeable as it’s the full width of the house plus a bit (so around 15-16m) and 5m deep. At least we have some time to get used to it before we actually lay any paving.

 Garage

Area stripped, trenches dug and concrete poured. Bill the BCO was on holiday when we needed the trenches inspecting so we had a stand-in chap come to inspect. He was concerned by the roots from the hedge so we were forced to dig deeper that we’d normally expect. The fact that there weren’t any roots anywhere near didn’t seem relevant to him and I can’t help thinking that he just wanted to find something for us to fix. Well, it’s ready now so we just have to wait for the brickies.
