floor joists split

I have a finished basement with suspended accoustical tile ceiling panels. The other day, after having a small leak from the upstairs bathroom, I removed the tiles under the bathroom. Unfortunatly, what I noticed is the joist running directly under bathroom toilet and bathtub is splitting. This joist also has a notch or two out of it due to plumbing hinderances etc.

From beam to beam is about 15 feet. The splitting is seen in about 6 feet of that span. However that 6 feet has the toilet and tub (drain end) above it. There is no room, that I can see to put a single solid joist up next to it as on one end of joist it rest by foundation (very solid) and on the other end is a wall with beam as header with no room above/below (solid).

I have re-inforced joists before by marrying joists on each side, the entire length and bolting the three together. However it doesn't appear that I've got this option on this house.

Any suggestions on how to repair this joist properly?

Make up some plywood repair plates the same height as the joist. Jack the joist up to level, attach a 3/4" by whatever high by 8' long plywood over the cracked section on both sides with subfloor glue and 2" drywall screws. you can build several layers this way IF you think it needs it, laping the joints of each layer of plywood far from each other. Let dry for couple days and then remove jack.
