This "Birthing Pool" is completely sterile is it how is that achieved?

No, but it should be free of the sort of pathogens that matter. To that
end it will typically have a liner which is thrown away after use. And the
water coming in should be safe if it derived from chlorinated cold mains
and properly stored and heated DHW (not guaranteed, of course, but mammals
have been giving birth with a sustainable success rate in far-from-sterile
conditions for a few million years now).
