This is a real tough one to answer. It is like going to the doctor and asking him "How long have I got Doc?". It can make a noise for a long time before the bearing finally seizes up or it may just start leaking. It may leak very slowly for a long time or it may just start gushing out. The safe thing to do is to park the car until you can fix it. You are gambling with the life of the engine and it can get expensive if you were to overheat it. Not to mention the towing bill. The bottom line, there is no "typical" time to failure. This is also why, when you are replacing ALL the seals and hoses you just replace the water pump. After 20 + years you cannot expect it to last much longer and it is not a simple remove-and-replace like on most other cars. The other possability is one of the idler bearings for the A/C is failing. Run the motor without the A/C belt and see if the noise goes away. If it doesn't it "could" be the alternator, not the water pump. Plan for and expect at least 1 bolt to break, either on the intake manifold or the water distribution pipe. If it is your first time it is a long 1 day project. Take notes and pictures for routing and placement of hoses, wires, etc. Be especially careful with those pesky copper washers. If you drop them you cannot get them with a magnet and you MUST be sure they are all in there when reassembling or you will have leaks. If you are not very flexible it is easier if you remove the engine cover. While you are in there you should also replace the spark plugs, ignition wires, cap, and rotor, idler bearings and belts. For a complete job replace the injector seals, vacuum hoses, have the fuel injectors tested and cleaned, air filter, adjust the valves, replace the O2 sensor and reset the mixture. When done change the oil and oil filter. As you can see this can turn into a large job best left for the winter if possible.
