Paul Industries is a nationwide process-equipment and sanitary-piping contractor working across Florida: purified water systems, sanitary process piping, cleanrooms, CIP and process equipment installation for supplement manufacturing, medical device production and beverage and citrus processing. Florida adds one requirement almost no other state imposes on a regulated plant: the process systems have to survive a hurricane season, and the recovery plan has to be an engineering document rather than an intention.

In Florida your rooftop air handler is a structural problem
This is the requirement that most surprises contractors arriving from other states. Under the Florida Building Code, mechanical equipment, appliances and their supports exposed to wind must be designed and installed to resist the wind pressures determined by the code, and roof-mounted units and their supports must be secured to the structure.
The Florida-specific part is how severe the calculation is. Design wind speeds range from roughly 115 to 140 mph inland and can exceed 170 mph in coastal regions. Florida requires a higher rooftop equipment factor than the national baseline, and uplift forces must be combined with lateral forces for buildings of all heights, not only tall ones. Miami-Dade and Broward sit in a High-Velocity Hurricane Zone with its own additional provisions.
For process work the consequences are concrete and expensive when missed. A cleanroom’s air handling units usually sit on the roof. So do condensers and often chillers. Outdoor tanks, their supports and their access platforms are all exposed structures. Equipment selected on process performance alone, with supports designed as an afterthought by whoever installs it, will not satisfy the code, and the correction happens after the units are craned into place.
The practical sequence is to establish the wind design criteria for the specific site before equipment is selected, because the support design, the roof structure’s capacity and sometimes the choice between rooftop and grade-mounted equipment all follow from it.
A power outage is a contamination event on a compendial water system
This is the Florida-specific point that gets underestimated. A purified water or WFI loop depends on continuous circulation, and on a hot loop, on continuous heat. Lose power for a day and the loop sits stagnant at ambient temperature, which is the exact condition biofilm needs. The system does not simply resume when power returns. It has to be sanitized and, depending on how long it sat and what your procedures require, potentially resampled before release.
That converts a weather event into lost production measured in days rather than hours, and it is entirely foreseeable. The engineering responses are ordinary: generator capacity sized to include the water system rather than only lighting and refrigeration, a documented restart and sanitization procedure written before it is needed, and loop design that drains rather than holding stagnant volume if a long outage is unavoidable.
The same logic applies to cleanrooms. A room that loses pressurization is no longer classified, and returning it to service means recovery testing and potentially recertification. Planning which rooms are on generator, and which are accepted as lost during an outage, is a decision worth making deliberately rather than discovering during the storm.
Three different rulebooks, and supplements is the largest
| Sector | Governing regime | Typical water grade |
|---|---|---|
| Dietary supplements | 21 CFR 111, with identity testing and batch records | USP Purified Water or treated potable |
| Medical device | 21 CFR 820 and ISO 13485 | Purified Water or DI by resistivity |
| Beverage and citrus | Food safety rules and 3-A sanitary design | Treated process water |
| Pharmaceutical and sterile | 21 CFR 211, Annex 1 where sterile | WFI at 0.25 EU/mL |
Florida’s supplement base is large, and the most common specification error here is importing pharmaceutical requirements into a 21 CFR 111 facility. A supplement plant does not need WFI, Grade A environments or full ASME BPE piping. Those specifications are not non-compliant, they are simply more than the rule requires, and on a supplement margin that difference matters.
What we build for Florida facilities
- Purified water systems Generation, storage and distribution designed with outage behavior and restart sanitization considered, not assumed away.
- Sanitary process piping Drainable, cleanable stainless specified to the regime that actually applies.
- Cleanrooms ISO 14644 classified environments, with a clear view of which rooms stay pressurized during an outage.
- Blending and batching systems Sanitary vessels and transfer for supplement and beverage production.
- Service contracts Including the post-outage recovery work that Florida plants need more often than most.
Ride-through is the design question that ties the rest together — high-purity water systems that can be held in recirculation through an outage, CIP/SIP systems with interrupted-cycle recovery logic, and passivation of loops that sit stagnant when power is lost.
Why Paul Industries in Florida
Because we mobilize nationally, which matters after a storm. When a region is recovering, local contractors are committed to whoever called first and are dealing with their own damage. A contractor who can bring crews from outside the affected area is not competing for the same stretched resources. The rest of the time, the value is the same as anywhere: one contract across water, piping and cleanrooms so nothing falls between vendors.

Frequently asked questions
What happens to a purified water loop during a power outage?
Circulation stops and, on a hot loop, heat maintenance stops with it, so the system sits stagnant at ambient temperature. That is the condition biofilm needs. The system cannot simply resume when power returns; depending on how long it sat and what your procedures require, it will need sanitization and potentially resampling before release. A one-day outage can therefore cost several days of production.
Should our water system be on generator power?
In Florida it usually deserves serious consideration, and it is frequently omitted because generators get sized for lighting, refrigeration and safety systems. Keeping circulation and heat maintenance running through an outage avoids a stagnation event entirely, and the comparison worth making is generator capacity cost against the production days lost to sanitization and resampling after each outage.
What should a post-outage restart procedure cover?
How long the system may sit before sanitization becomes mandatory, the sanitization method and cycle, what sampling is required before release, who authorizes the return to service, and the same questions for cleanrooms that lost pressurization. The value is in having decided it in advance. Writing that procedure during a recovery, under pressure to resume production, is how shortcuts get taken.
Does a Florida supplement plant need Water for Injection?
No. Dietary supplement manufacturing runs under 21 CFR 111, which has no WFI requirement. USP Purified Water is typical where a compendial grade is needed, and appropriately treated potable water suffices for some applications. Specifying a hot WFI loop adds very substantial capital and running cost for a standard no inspector will hold a supplement manufacturer to.
What does a cleanroom need after losing pressurization?
At minimum a return to its defined operating state and confirmation it still performs, which usually means recovery testing and, depending on your procedures and how long it was down, recertification to ISO 14644-2. The practical planning decision is which rooms are on generator and which are accepted as lost during an outage, because that determines how much testing you face afterwards.
Do you serve medical device manufacturers in Florida?
Yes. Device work runs under 21 CFR 820 and ISO 13485 rather than the drug rules, which changes the documentation basis and usually means USP Purified Water or DI rather than WFI. Typical scopes are ISO 7 and ISO 8 assembly and packaging environments, purified water and DI for rinse duty, and the sanitary distribution feeding them.
What is different about citrus and beverage processing?
It follows food safety rules and 3-A sanitary design rather than cGMP, so the documentation burden is lighter and the specification is more cost-driven. What it does demand is genuine cleanability under heavy seasonal throughput, plus acid-resistant material selection, because citrus is aggressive to equipment in ways that surprise contractors used to neutral products.
Can you get crews to Florida after a storm?
Yes, and that is a real advantage of mobilizing nationally. After a significant weather event local contractors are committed and frequently dealing with damage of their own, so a plant relying solely on local resources joins a queue. Bringing crews from outside the affected region avoids that. It is worth having the conversation before the season rather than during it.
Does Florida energy cost affect design decisions?
Modestly. Industrial electricity averaged 8.50 cents per kilowatt-hour in 2024 against a national average of 8.13 (EIA), so slightly above the midpoint. Insulation and efficiency are worth reviewing on continuously running loads, but in Florida the stronger argument for controlling heat loss is usually reducing the cooling load that hot uninsulated pipework imposes on an already heavily loaded building.
How do I get a quote for a Florida project?
Use the form on this page or call 201-450-8280. Useful inputs are the product and its regulatory regime, your water demand at peak, whether classified environments are required by regulation or by a customer, and what is currently on generator power. If storm resilience is part of what you want reviewed, say so, because it changes how we would design the water system rather than being an add-on afterwards.
How should a project be scheduled around hurricane season?
With envelope-critical work, equipment deliveries and commissioning outside the peak months where possible, and with a defined plan for securing the site if a storm approaches during construction. A partially complete building is considerably more vulnerable than a finished one.
How is a construction site secured before a storm?
By removing or securing loose materials and equipment, closing the building envelope as far as the works allow, protecting installed equipment from water ingress, and documenting the state of the site. Sites that plan this once at the start of a project execute it far better than sites improvising.
Are contractors available after a regional storm?
Demand spikes across the whole region simultaneously, so the honest answer is that availability is constrained exactly when it is needed. Clients with existing relationships and documented systems get served faster, because the assessment and the parts list can be produced without a survey.
What should be documented before the season?
The system as-built, isolation points, the standby arrangement, spares held, and the shutdown and restart procedures. That package is what allows a rapid response, and it is impossible to assemble during an emergency. It is also what supports an insurance position afterwards.
Can several scopes be combined into one shutdown?
On seasonal plants the off-season provides an unusually generous window, so combining piping, vessel work, surface remediation and equipment modification into one planned programme is both practical and considerably cheaper than separate mobilisations.
What lead times should be expected?
Equipment governs, and in this state the additional consideration is that regional demand spikes after a storm, which lengthens availability of exactly the items a damaged plant needs. Holding critical spares is worth more here than in states without that exposure.
What should be prepared before requesting a quote?
The process requirement, the seasonal or continuous operating pattern, the resilience expectation including any standby arrangement, the site’s flood and wind exposure, and the documentation required. The resilience expectation belongs on that list here in a way it does not elsewhere.
What is the commonest Florida planning failure?
Designing for normal operation and treating the outage as an exception, when in this state extended outages are a recurring feature. The plants that recover quickly are the ones that decided in advance what they would do, and the ones that lose weeks are improvising a procedure during the recovery.
What is the single most valuable resilience measure?
Standby power sized to hold the things whose loss is expensive to reverse: cleanroom pressurisation and water system circulation. Both are small loads, both prevent multi-day recoveries, and both are far cheaper than the production time they protect.
How quickly can you respond if a system fails?
Far faster at a plant we already know, because the first hours are otherwise spent establishing what is installed. In a state where regional events constrain everyone’s response simultaneously, having the system documented in advance is the difference between days and weeks.
How is flood exposure assessed for a site?
By establishing the site’s flood risk and then locating vulnerable equipment above the credible level, which for plant rooms, electrical equipment and water treatment is a design decision with a large consequence. Equipment standing in flood water is replaced rather than cleaned.
Should critical spares be held locally?
In this state more than most, because regional demand after an event exhausts local supply exactly when it is needed. Holding the filters, seals, membranes and instruments that a recovery requires converts a supply-chain wait into a same-week restart.
What does business continuity actually require here?
Knowing what stops production, how long each item takes to restore, and which of those can be shortened by standby power, spares or a written procedure. Most plants discover the critical path during their first extended outage rather than identifying it in advance.
Does the device and pharmaceutical side face the same issues?
The same outage exposure with a heavier consequence, because classified space and qualified utilities take longer to return to a demonstrable state than general production equipment. Resilience investment is easier to justify in those facilities precisely because recovery is slower.
How does seasonality interact with storm season?
Awkwardly for citrus, because the season and the storm risk overlap, so a plant may be running when a storm arrives and idle when it would have been convenient to do remedial work. Planning both calendars together is what makes the off-season work achievable.
What is worth doing during any Florida shutdown?
Inspecting and repairing insulation cladding, checking seals and elastomers, testing the standby arrangement under load, verifying the drain points actually drain, and rehearsing the shutdown procedure. All are impossible while running and all directly affect how the next event goes.
