Tell us what's happening
The short answer
Roof water emptying at the base of a wall is a connection problem. The downpipe goes to a stormwater pit or line, and an ag line drains the ground beside the wall.

Questions and answers
Deep enough to sit under the water you are trying to catch, which usually means down at the base of the wall or the footing line. It goes in on gravel and inside a filter sock so the slots do not silt shut.
It is the first thing to try on damp brickwork, and usually a modest job. Roof water landing at the base of a wall keeps the ground saturated, which is what pushes moisture through to the inside.
To a stormwater pit or line that sits lower than the ag pipe, so water always runs out of it and never back in. It never goes to the sewer.
Yes, although it means digging out the backfill behind the wall to reach its base. If the wall is already leaning badly, we tell you, because some walls need rebuilding rather than draining.
The underground pipe may be blocked or broken, so water backs up and leaks out at the riser. A hose test and the camera show whether the water is actually getting away.
