Paul Industries delivers high-purity water systems for pharmaceutical manufacturers as a single-source supplier and installer. We design, fabricate, install, passivate, and validate high-purity water systems – the USP Purified Water and Water-for-Injection generation, storage, and distribution loops that a regulated plant runs on – built to the standards your process and your auditors require.
What pharmaceutical manufacturers need from high-purity water systems
Pharmaceutical manufacturing lives and dies by cGMP compliance – FDA 21 CFR Parts 210/211, validated systems, and audit-ready documentation. Whether the process is oral solid dose, sterile injectables, or API synthesis, the utilities behind it (process water, clean steam, sanitary piping, CIP/SIP) have to be designed, installed, and documented to survive an FDA inspection.
For this work, that means cGMP (21 CFR 210/211) compliance, validated IQ/OQ/PQ turnover, USP-monograph water quality, and fully documented, traceable installations – not as an afterthought, but engineered in from the first drawing.
What we deliver
- USP Purified Water (PW) and Water for Injection (WFI) generation – RO/EDI, multi-effect or vapor-compression distillation
- Storage and distribution loops engineered for turbulent flow, hot-water or ozone sanitization, and dead-leg-free design
- Complete generation-through-point-of-use build: skids, tanks, loop piping, instrumentation, and controls
- Sanitization strategy (hot water 80C+, ozone, or clean steam) matched to your monograph and risk profile
- IQ/OQ/PQ support and turnover documentation for the full water system
One accountable partner
Most pharmaceutical projects get split between an equipment supplier and an install contractor – and the validation burden falls in the gap between them. Paul Industries closes that gap by self-performing the whole scope, from supply through documented turnover.

Frequently asked questions
What water grade does pharmaceutical manufacturing require?
Pharmaceutical manufacturing uses USP purified water for non-parenteral products and cleaning, and Water for Injection for parenterals and final rinses. The grade follows the dosage form and process step. Paul Industries designs, builds, and validates both for pharma sites nationwide. Call 201-450-8280.
What is the difference between purified water and WFI in pharma?
Both meet the same conductivity and TOC limits, but WFI must also meet a strict endotoxin limit and is produced by distillation or validated RO plus UF and held hot. Purified water suffices for oral and topical products; WFI is required for injectables.
What USP standards govern pharmaceutical water?
USP <1231> covers water for pharmaceutical purposes, <643> sets the TOC limit, and <645> sets conductivity. WFI follows its monograph including endotoxin limits. cGMP and FDA expectations apply to the entire system, verified through validation.
Why is pharmaceutical water so heavily regulated?
Water is the highest-volume ingredient and cleaning agent in pharma, contacting products and equipment directly. Contaminated water can carry microbes, endotoxin, or ions into medicines, so systems are engineered, validated, and monitored to prevent quality failures and protect patients.
How do you size a pharmaceutical water system?
Sizing balances peak simultaneous point-of-use demand, batch schedules, storage turnover, and future growth. Generation capacity, tank volume, and loop flow are matched so recirculation velocity holds during peak draws. Paul Industries sizes from a demand study. Call 201-450-8280.
What causes an FDA observation on a pharma water system?
Common findings include inadequate microbial control, dead legs, insufficient sanitization or validation, poor trend monitoring, and undocumented changes. Robust ASME BPE design, drainability, monitored sanitization, and complete IQ/OQ/PQ records prevent most observations.
How is a pharmaceutical water system validated?
Validation runs IQ, OQ, and PQ. A three-phase PQ samples every point of use daily then weekly over about a year, tracking conductivity, TOC, microbial, and endotoxin data to prove the system consistently produces compliant water before and during routine use.
What materials are required for pharma water piping?
Distribution uses 316L stainless steel, electropolished and passivated per ASME BPE, with documented orbital welds and sanitary connections. Elastomers are USP Class VI. These materials give corrosion resistance and cleanable, crevice-free surfaces required for cGMP.
How long does it take to build a pharmaceutical water system?
Timelines range from months for a skid and loop tie-in to longer for full WFI generation with a lengthy PQ. Shop fabrication parallels site work to compress schedule. Paul Industries provides firm timelines after design and demand review. Call 201-450-8280.
How much does a pharmaceutical water system cost?
Cost is driven by grade, flow capacity, storage, distribution length, materials, and validation scope. WFI generation with a hot loop costs far more than a small purified-water skid. Paul Industries scopes cost after a feedwater and demand review, not from a template.
Do you need WFI for oral solid dose manufacturing?
Usually no. Oral solid and many topical products use USP purified water for granulation, coating solutions, and cleaning. WFI is reserved for parenterals and product-contact final rinses. Paul Industries matches the grade to your dosage forms to avoid over-building.
How do you prevent contamination in pharmaceutical water systems?
Contamination is prevented by continuous recirculation, hot or ozone sanitization, drainable zero-dead-leg design, integrity-tested vent filters, and routine microbial and endotoxin trending. These controls are engineered in and documented for audit.
Can you validate cleaning water for pharma equipment?
Yes. Cleaning and final-rinse water quality is part of cleaning validation. Paul Industries builds CIP systems and verifies coverage with riboflavin testing, ensuring rinse water meets USP grade so residues clear to acceptance limits. Call 201-450-8280.
Can Paul Industries support a pharma facility nationwide?
Yes. Paul Industries fabricates in Kilmarnock, Virginia and mobilizes field crews to pharmaceutical sites in all 50 states for installation, validation, emergency repair, and maintenance under one contractor. Call 201-450-8280.
How do you tie water systems into existing pharma utilities?
Paul Industries ties new generation, storage, or loops into existing steam, clean steam, chilled water, and controls, staging work to limit downtime in operating plants, then revalidating the affected sections to keep the system in compliance.
Why use a single-source contractor for pharmaceutical water?
A single-source contractor designs, fabricates, installs, and validates the system as one accountable party, avoiding gaps between separate skid, piping, and validation vendors. For audited pharma projects, that continuity reduces compliance risk and speeds startup. Call 201-450-8280.
What pharmaceutical requirements do you build to?
Our high-purity water systems work for pharmaceutical manufacturers is built around cGMP (21 CFR 210/211) compliance, validated IQ/OQ/PQ turnover, USP-monograph water quality, and fully documented, traceable installations. Every installation ships with the documentation your quality team needs.

What do pharmaceutical manufacturers require from a high-purity water system?
| Requirement | What it means |
|---|---|
| Water grade | USP Purified Water or WFI depending on product route; WFI required for parenterals |
| Governing limits | USP conductivity and TOC; WFI adds a bacterial endotoxin limit |
| Distribution | Hot-held or ozonated loop, continuously circulated, dead-leg-free at every point of use |
| Sanitisation | Thermal or ozone, proven to reach the furthest point at temperature and contact time |
| Construction | ASME BPE, orbital-welded, ASTM A270 tube, passivated to ASTM A967 |
| Documentation | Weld logs, material traceability, passivation verification, calibration certificates |
| Qualification | IQ, OQ and PQ, typically with a multi-week PQ sampling campaign at every use point |
| Change control | Any modification to the loop triggers requalification of the affected section |
Do you handle validation, or just installation?
Both. For pharmaceutical water the validated state matters more than the initial qualification, and Paul Industries builds for both. We execute commissioning and IQ, OQ and PQ including the multi-week sampling campaign across every point of use, then establish the monitoring, trending and periodic review that keep the system in a validated state afterwards. That distinction is the one inspectors probe hardest: a loop qualified three years ago that has since had an undocumented control change, an overdue calibration and unexplained excursions is not validated regardless of what the original report says. Installation alone leaves you holding equipment rather than evidence.
Can you take a project from design through startup?
Yes. On a pharmaceutical water system the sequencing between design and startup is unforgiving, and one contract is what keeps it intact. Passivation must follow every weld including the final tie-ins, sanitisation must follow passivation, and the sampling campaign must follow sanitisation before any water is released. Each handover between contractors is a place that sequence breaks, most commonly by passivating a loop before the tie-ins are made so the connecting joints are never treated. Holding design through startup together means the sequence is planned once and executed in order rather than reassembled from separate scopes.
