<p>To provide a water producing system that produces fresh water by treating treatment target water A at a first semipermeable membrane treatment plant 2, that mixes concentrate resulted by the treatment carried out at the first semipermeable membrane treatment plant 2 with treatment target water B, and that treats the mixed water at a second semipermeable membrane treatment plant 3 to produce fresh water, characterized in provision of a bypass line that allows the treatment target water A to be mixed with the treatment target water B or the concentrate while bypassi ng the first semipermeable membrane treatment plant 2, so that the second semipermeable membrane treatment plant 3 can operate even when any trouble occurs at the first semipermeable membrane treatment plant 2 and treatment cannot be carried out thereby.</p> |
