If you've ruled out a leaking hose bib and the water isn't running between the outside wall of the sleeve and concrete on the interior side of the foundation, ok.
It sounds like there's a chance there isn't a hole in the water pipe. Perhaps when it rains, water leaches into the ground and at the start of the casing, furthest away from the house, water seeps inside the casing. Perhaps the casing and pipe slope down towards the house and the water that seeps into the casing runs into the house. If this, the best fix is at the start of the casing with an elastomeric fernco fitting.
Then again, perhaps there's an issue with the brick facade not draining properly or water penetration from above and water has worked its way down exposed rebar (or a crack) at the sill plate which is very close to the sleeve penetrating the foundation.
Either way is going to be a PITA, but think the first scenario would cost less to fix.
