I'm considering the idea of converting our 55,000 litre swimming pool
(better known as the money well) into a rainwater tank. It's inground
and made of very thick and solid concrete, with no leaks.
Has anybody out there done this or heard of it being done. From what I
have read, it seems feasible, and the pump on the pool now appears to
be the right power to supply the house.

Any and all hints and tips would be appreciated.
