Maybe Man From Atlantis? The opening credits don't match that description, but it is a later 70's TV show where there are a lot of people running around in blue skinsuits which takes place at an oceanic research facility, so plenty industrial and has lots of pools.
Also, the Wikipedia entry notes:
In Italy, the series is notable to be one of the early successes of the then interregional network Telemilano, future Canale 5, that began to air the series on February 11th, 1980 under the name L'Uomo di Atlantide.
