Digging new gas and water line

[J Pearse]

Hi,

The 1930's semi I have just moved into has no gas line and a lead water line.  As such, I am planning to dig a trench in the front driveway for the specs of the water line (>75cm deep etc) and then once inspected partially backfill it and then let the gas company lay their line.

 

I have two main questions.

 

1) what do you do when you get to the foundations? Knock out a brick and lay waste pipe then poke the main pipe through? Then just route the pipe under the subfloor ventilation to the kitchen or wherever you want the stopcock?

 

2) I have just noticed there's an inspection hatch with access to an elbow of a rainwater runoff for the front house aspect.  Do you just dig around these? (See pics).  Further question is that it's currently raining steadily and I can't see any water flowing around then bend.. would it be old and disused?  In the pics the red dashed line is where the gas and new water line need to run.  The blue is where I'm assuming the waste pipe runs to the downpipe.

 

Many thank,

Jack
