Category: 07 Rain water drainage

Saturday, 2 October 2010 / 10:33

Not much has happened over the past two weeks, just the odd day when a little more brick work has appeared and this Thursday the pipes for the rain water drainage were laid in position. Yesterday was a day of rain which means that the water table has risen: it’s only about a foot below the surface, so the pipes are sitting in water.

In the foreground you can see part of the existing pipe which runs down to the ditch at the end of the garden. This is where some of the water from the house currently drains. Unfortunately it’s about 250 mm higher than than the new pipe so one off my tasks is to install a new pipe which starts at the right level and comes out in the ditch. I’ll replace the old clay pipe with some new plastic piping. The advantage of the plastic piping is that, due to the pipe being more slippery, you can have less fall and roots don’t get into the joints and fill up the pipe.

William and Ben have worked out where the down pipes are going to go and the tee pieces are positioned accordingly. This one will be in the internal corner where the conservatory meets the house. This means we avoid having it on the external corner of the conservatory which will be most seen.

Another down pipe receiver. This down pipe will take the water from the existing South West side of the house as well as some of the new part. The existing one which can be seen nearby goes into a pipe which goes off under the drive and into a pipe which seems to go down the boundary, but I think it’s partially blocked.

At long last, after a break of nearly a year, William and his band of men, Ben, Orien and Neil are back. It’s an uplifting sight to see a digger, albeit a Korean one, with it’s bucket dipping down into the soil. Yesterday they started digging the trench which will take  the rain water drainage pipe down to the ditch. There’s no point having a soak away here as the water table is high; makes much more sense to pipe it straight into the ditch. The water will flow into Bartley Water and will eventually pass the ends of the gardens of my friends who live in Rushington before flowing into the end of Southampton Water at Eling.

There’s just about enough fall from the new pipes on the extension to the ditch. It only needs to be 1:100. The trench is about 550 mm deep at the ditch end.

Pipe will go under the fence and come out in the ditch. Posts to left are driven to the left of the pipe run so that the depth can be gauged.

The new pipe goes diagonally across the garden to avoid tree roots. Large roots have been left and the pipe runs underneath.

Trench back filled with gravel and soil.
