There are good ways and bad to achieve this. Since there is no explanation as to why these need to remain separate I will not mention it any further or offer any advice about that.

Simply get a switch that support 802.1q and layer 3 routing, create 3 VLANs and connect router A and all those PCs to ports in VLAN 1 and likewise router B and those PCs to ports in VLAN 2 and finally servers into VLAN 3.

Users will on both networks will be able to see the servers and still use their own internet connections.
