WATER SYSTEM

DESCRIPTION:
Potable water is stored in storage tanks. These tanks are built by RCC. Walls, Floors and Ceiling are plastered with cement. The entire transfer pipelines are of GI (Galvanised Iron) material.

Storage tanks are cleaned as per SOP of “Sanitization of main overhead potable water storage tanks”.

Potable water from storage is then passed through de – ionized water plant to get the purified water. Detailed procedure for operation of de – ionized water plant is mentioned in the “Procedure for Charging of De – Ionizer”. The procedure and frequency of sanitation and passivation of de - ionized water distribution system is as per procedure and is recorded in respective departments.

De – ionized water is then doubly distilled, and passed through 0.5 micron and 0.2 micron filters. This water is used in the washing and formulation processes of injectable section.

Schematic diagram of Water System for Injectable Section is shown in Fig 2.

Water produced from the De – Ionized Water plant, Distillation Unit and after passing through 0.2 micron filter are sampled and analyzed daily for chemical parameters and for microbiology as per USP requirements.
