MERCHANT SHIPPING (SEAFARERS) (CREW ACCOMMODATION) REGULATION - SECT 30

Supply of fresh water

(1) The fresh water laid on to washbasins, baths and showers shall be supplied
from tanks of suitable capacity taking account of the number of the crew and
the maximum number of days that may elapse between successive replenishments
of water; provided that if plant is installed on board for the supply of fresh
water the storage capacity may be reduced, but the tanks shall still be
sufficient to provide at least 2 days' supply.

(2) The washing water storage tanks, any manholes leading into them, and all
pipes and other parts of the distribution system for the washing water shall
be so arranged and constructed as to allow sufficient maintenance and minimize
any risk of contamination.

(3) Where gravity service tanks are fitted they shall be directly connected
with the ship's main fresh water storage tanks.

(3A) Where fresh water is produced by plant installed on board, the water so
produced shall be treated by a suitable automatic means of disinfection.

(4) In ships of 1000 tons or over any primary pumping necessary for the supply
of fresh water in crew accommodation shall be by mechanical power; alternative
pumping arrangements shall be provided to supply fresh water in the event of a
breakdown of the primary pumping system. When an enclosed pressure system is
employed, pumps provided for the alternative pumping system shall be power
operated and all pumps required for primary and alternative pumping shall be
fitted with automatic controls. (Enacted 1995)
