as 74 UA fj points out - a cistern fed slowly from a poor producing well would work fine. Takes two pumps - one in the well and one drawing from the cistern to feed a pressure tank. Although where I live - unless you bury it, locate it indoors, or heat it ... you have very small skating rink in February.
well pump question?

Pump tersts can be accomplished easily just by adjusting the pressure of the well discharge. It'll be limited, but will probably tell you what you need to know.
You do need to know what the water level is in the well (both during pumping and static). Without that, it does not matter what you are doing as far as well production. It is all just a guess.
HP is not the end all be all of a pumping rate. Pump designs vary wildly. Along with number of bowles, and blade design. Goulds are good pumps. If you pull the pump you will be able to get a pump model from it, along with the HP of the electric motor.
Also, pump columns tend to degrade over time which can easily cause the leaking over time. You may just be able to pull the pump and replace the column and call it good.
5gpm is pretty weak even for a domestic well..

A 1/2 HP Goulds Submersible pump produces around 4 gal per min at 275 ft ( less with a hole in the line) A 3/4 HP pump at the same depth puts out around 7 GPM and a 1 HP will do close to 10.
You have 1 1/2 gallons per ft of 6" casing you have about 260 gallons available with no recovery. Even if your well only produces a few gallons per min you still have a lot of water above the pump. If you never ran out of water on your 1/2 HP I doubt your water use will change much with a 3/4 HP. If your worried then install a PumpTech or low water cutoff switch to protect the pump from running dry.
I like the variable speed pumps but that would require changing out your new well tank.
