Potable water supply on ships
The potable water required on ships is located in potable water tanks and is either bunkered in ports or processed at sea from seawater itself. The quality of the water must meet the requirements of the local Drinking Water Ordinance and must be regularly tested; the results are to be documented in the ship's logbook.
Systems for using seawater
Due to its salt content, seawater places particular demands on the material used with respect to corrosion resistance. In this environment, copper and nickel alloys are particularly suitable. Accordingly, Viega uses the alloy CuNi10Fe1.6Mn for its Seapress seawater-resistant product.
