Drainage - how far should pipes be from wall foundations?

I am planning a "timber on dwarf wall" type conservatory in place of, and slightly larger than, an ageing flat roof porch.

The WC soil pipe (to septic tank) and the bath/sink waste pipe (to soakaway) will need to be moved (approx 1m) along the front of the house to make space for the conservatory.

The new underground WC soil pipe will have to run parallel to the new cons. wall straight out in front of the house and connect in to the existing run to the septic tank.

My initial questions :-

- how close is it advisable (and allowable?) to have the drains to the foundation of the new conservatory wall? (& is this part worth bothering the Bldg Inspector?) This will dictate how wide the conservatory can be.

thanks in advance Andy
