Shipowners calling at Singapore face a 24% increase in the cost of purchasing potable water, under measures outlined by the Maritime and Port Authority (MPA).

The MPA said the increases will be phased in over a two year period with the revisions coming into effect on 1 July 2017 and then 1 July 2018.

The potable water tariff will remain unchanged at SGD 1.92 ($1.37) per cubic metre (cbm), but the waterborne fee (WBF) and the water conservation tax (WCT) are set to increase.
