Our aquarium does. We pump seawater from the Otago Harbour (fortunately it's not polluted!!!) into large reserviours which is then used by both the aquarium and the research lab. The water is filtered through sand filters to remove any silt etc (the Harbour is very shallow and gets pretty stirred up if it's windy!) . We use large venturi pumps and have several backup pumps including one run by a diesel genny.
