  2. 02

    Design

    Design pretreatment, generation, storage, distribution, materials, instrumentation and automation.

  3. 03

    Install

    Build and install equipment, piping, instruments, software and infrastructure while maintaining hygienic design and documentation.

  4. 04

    Qualify

    Execute DQ, FAT/SAT, commissioning, IQ/OQ/PQ, CSV and requirements traceability.

  5. 05

    Operate

    Manage sampling, TOC, conductivity, microbiology, sanitisation, trending and maintenance.

  6. 06

    Improve

    Manage periodic review, deviations, biofilm, rouging, change control, retrofit and lifecycle improvement.

PROJECT LIBRARY

Technical content organised around project decisions.

REGULATORY FOUNDATIONS

The project must start from the right regulatory framework.

Water quality, design, qualification and data governance should clearly distinguish pharmacopoeial requirements, GMP expectations, guidance, technical standards and good engineering practice.

01

EMA / Pharmaceutical Water

Selection of the appropriate water quality for pharmaceutical use and application of European expectations.

02

Ph. Eur. / PW & WFI

Monographs and applicable chapters covering Purified Water, Water for Injection, TOC, conductivity, endotoxins and microbiological control.

03

EU GMP Annex 15

URS, DQ, FAT/SAT, commissioning, IQ/OQ/PQ, change control and lifecycle qualification.

04

Annex 11 / Part 11

Automation, electronic records, access control, audit trails, data integrity, backup, restore and periodic review.
