Big hole

The guys have done a smashing job, digging around (from bottom of the picture to top):
- the new gas pipe (yellow plastic)
- the waste pipe for what ? we don't know (big greyish pipe)
- the FLIMSY water pipe (15mm copper, looks yellow on the picture)
- the old gas pipe (rusted and fairly straight)
- the big teraccota glazed waste for our toilet (brown pipe nearest the top)

Now we need to figure out what we'll do with these pipes...
