The problem of potable water supply is becoming increasingly relevant. This problem is particularly important in the countries of Oceania, where neither surface, nor subterranean water is unavailable due to the harsh terrain and climate. Therefore, construction of marine water intake structures is the only solution. Peculiarities of construction of water intake facilities and their operation in the environment of the Pacific Ocean are considered by the author. The author provides his layout solutions of water intake structures. The author has given up the idea of a water intake facility capable of taking water from the channels because the sand brought by the waves from the bottom may inflow into the water inlet structure. Besides, channels drain in the low tide period; therefore, water intake facilities remain idle.Also, high aggressiveness of the sea water constitutes another problem. The sea water may damage any water intake structure, as some of their elements are made of reinforced concrete, while others are made of steel. Steel corrosion resistance may be improved by alloying additives (chromium, Nickel, copper, etc.), or, alternatively, by a zinc and aluminum coating which must be 120—250 microns thick.
