2. General principles for pharmaceutical water systems
2.1 Pharmaceutical water production, storage and distribution systems should be
designed, installed, commissioned, qualified and maintained to ensure the reliable
production of water of an appropriate quality. It is necessary to validate the water production process to ensure the water generated, stored and distributed is not beyond the designed capacity and meets its specifications.
2.2 The capacity of the system should be designed to meet the average and the
peak $ow demand of the current operation. If necessary, depending on planned
future demands, the system should be designed to permit increases in the capacity
or designed to permit modi"cation. All systems, regardless of their size and
capacity, should have appropriate recirculation and turnover to assure the system
is well controlled chemically and microbiologically.
