Paul Industries is a nationwide process-equipment and sanitary-piping contractor working across Texas: high-purity water, sanitary process piping, cleanrooms, CIP/SIP systems and turnkey process equipment under one contract. Texas is one of the largest build-outs in our sector right now, with Eli Lilly constructing a $6.5 billion plant near Houston, and it combines that with the cheapest industrial energy of any large manufacturing state at 6.12 cents per kilowatt-hour against a national average of 8.13 (EIA, 2024).

Cheap energy changes which design decisions are worth making
Texas industrial electricity averaged 6.12 cents per kilowatt-hour in 2024, which is 25 percent below the national average and roughly a third of what the same load costs in California. On a continuously running process that difference compounds into real money over a decade, and it shifts the engineering calculus in a way most national design standards do not account for.
Concretely: a continuously circulating hot water loop drawing 15 kW costs about $8,000 a year to run in Texas and about $28,300 in California. Efficiency measures that pay back in three years on the coast can take a decade here. That does not make them wrong, but it does mean a design imported from a Northeast or California plant frequently carries capital cost that Texas economics will never recover.
The inverse also applies and matters more. Because energy is cheap, the temptation is to under-insulate, oversize air changes and skip heat recovery. That is defensible while power stays cheap and becomes expensive if it does not. We would rather make those trade-offs explicitly, with the ten-year number visible, than inherit either a gold-plated design or a deliberately careless one.
Texas is running several different regulated regimes at once
Unlike states with one dominant cluster, Texas carries pharmaceutical, medical device, food and protein processing, and a very large chemical sector simultaneously, and they answer to different rulebooks. Getting the regime right at the start is the single largest cost variable on a Texas project.
| Sector | Where it concentrates | Governing regime |
|---|---|---|
| Pharmaceutical and biologics | Greater Houston, expanding fast | 21 CFR 211, EU GMP Annex 1 for sterile, ASME BPE, WFI at 0.25 EU/mL |
| Medical device | Dallas-Fort Worth, Austin | 21 CFR 820 and ISO 13485, ASTM F86 for implants, usually PW rather than WFI |
| Food and protein | Statewide, heavy in the panhandle and east | USDA FSIS for meat, 3-A sanitary design, washdown-rated construction |
| Chemical and API | Gulf Coast corridor | ASME B31.3, Category M where toxicity requires it |
| Distilling and beverage | Austin, Hill Country, Dallas | TTB permitting and food-contact sanitary design, not cGMP |
The expensive error we see repeatedly is a food or beverage project specified as though it were pharmaceutical, carrying ASME BPE piping and qualification documentation it will never use. The opposite error, a pharmaceutical project scoped to food standards, is rarer but considerably worse.

Why Paul Industries in Texas
We are a nationwide contractor rather than a Texas firm, and on a market expanding this fast that is an advantage rather than a caveat. Crew availability is the binding constraint on Texas process projects at the moment, not equipment delivery, and a contractor who can mobilize crews from outside the state is not competing for the same stretched local labor pool that every Houston project is drawing from. The same procedures, welder qualifications and documentation standards apply wherever we work.

Frequently asked questions
Do you have crews available in Texas?
Yes, and we mobilize nationally rather than depending on a single local labor pool. That matters in Texas specifically, because the current pharmaceutical build-out is absorbing certified sanitary welders faster than the region produces them. A contractor drawing only on Houston-area labor is competing against every other project in the corridor, which is why crew reservation timing is worth more than a marginally better equipment price.
How much does cheap Texas power actually save on a process system?
On a continuously running load, a great deal. Industrial electricity averaged 6.12 cents per kilowatt-hour in Texas in 2024 against 8.13 nationally and 21.53 in California (EIA). A hot loop drawing 15 kW continuously costs roughly $8,000 a year here and about $28,300 in California. Over ten years that is the difference between an efficiency measure being obviously worth it and being marginal.
Should we still insulate and recover heat if energy is cheap?
Usually yes, but the justification is different. In a high-cost state insulation pays back on energy alone in a few years. In Texas the payback is longer, so the stronger arguments are process stability, personnel protection from hot surfaces, and reducing the cooling load that hot uninsulated pipework imposes on the building. We would rather make that case honestly than pretend the energy payback is something it is not.
Can you support the Lilly project or similar large sites?
We work as a process-systems contractor and subcontractor on projects of that type, delivering high-purity water, sanitary piping, cleanroom and CIP/SIP scopes. Very large campuses are delivered through many packages rather than a single award, so the useful conversation is about a specific scope rather than the project as a whole. Contact us to discuss a package.
What is different about a Gulf Coast chemical or API project?
The piping code, primarily. Chemical and active pharmaceutical ingredient work sits under ASME B31.3 rather than being purely a BPE question, and where the fluid is toxic enough that a single small leak could cause serious irreversible harm, Category M fluid service applies with its more demanding design and examination requirements. That determination should be made early, because the examination record cannot be retrofitted.
Do Texas food and protein plants need the same piping as pharma?
No, and specifying it is an easy way to overspend. Food and meat processing follows 3-A sanitary design and, for meat and poultry, USDA FSIS requirements, which demand genuine cleanability and drainability but not the qualification apparatus of a drug plant. What protein plants do need that pharmaceutical plants do not is construction that survives daily high-pressure caustic washdown, which drives material selection and support design.
Which parts of Texas do you cover?
Statewide, including Greater Houston and the Gulf Coast corridor, Dallas-Fort Worth, Austin and San Antonio. Because we mobilize crews nationally rather than from a single depot, coverage is a scheduling question rather than a geographic one. For projects in a running plant the more important variable is usually your available outage window, not the distance.
How long does a high-purity water system take to bring online in Texas?
The installation is predictable; the constraints are crew availability and qualification. Performance qualification of a compendial water system runs through an extended multi-phase sampling program measured in weeks, and it cannot be compressed by adding people. The practical consequence is that the water system needs to be complete and operating well before your first engineering batch, so it should be started earliest and usually is not.
Can you work in a live plant without stopping production?
Usually, with planning. We prefabricate offsite and make tie-ins during production windows or a planned shutdown. The honest constraint is that some tie-ins need the system drained, cleaned and released before it returns to service, and each return costs testing time. Those scopes get grouped into one planned outage rather than spread across several, because three short outages typically cost more than one longer one.
What standards apply to a sterile injectable facility in Texas?
The same as anywhere in the United States: 21 CFR 211, EU GMP Annex 1 for contamination control strategy, ASME BPE for wetted surfaces and joints, ASME Section IX for welder qualification, and Water for Injection meeting USP 643, USP 645 and an endotoxin limit of 0.25 EU per milliliter. There is no Texas-specific pharmaceutical standard; what changes regionally is cost, crew availability and schedule.
Do you passivate and document stainless after installation?
Yes. We passivate to ASTM A967 with cleaning per ASTM A380, and record procedure, chemistry, contact time, temperature, rinse quality and final verification. On implant or device work ASTM F86 applies to the product itself, which is a separate activity from passivating the equipment that handles it. Both get documented, because an auditor will ask which standard applied to which surface.
How do I get a quote for a Texas project?
Use the form on this page or call 201-450-8280. Useful inputs are the product and its regulatory regime, the classification or water grade you need, approximate square footage or loop length, your target qualification date, and your outage windows if the plant is running. If you have a user requirement specification or basis of design, send it; if not, we can help define scope before anything is priced.
What are the main manufacturing regions?
The Gulf Coast chemical and refining corridor around Houston, the growing pharmaceutical and life science investment across the state, the Dallas-Fort Worth industrial and device base, and very large food and protein processing throughout. Those four have different regulatory frameworks and different engineering expectations.
Does hurricane season affect project planning?
On the coast it should. Work that opens the building envelope, equipment stored outdoors and commissioning schedules all carry season risk, and the recovery time after a significant storm affects the whole regional supply chain rather than just the site. Scheduling envelope-critical work outside the peak months is ordinary prudence here.
What environmental permitting applies?
The state environmental authority administers air and water permitting, and process projects touch it through combustion equipment, emissions and trade effluent. Anything involving a new emission source or a significant discharge change needs establishing early, because the authorisation timeline rarely fits a construction programme already underway.
Does water availability constrain projects?
In parts of the state it genuinely does, through allocation and cost rather than outright prohibition, and it matters most for facilities whose expansion requires additional supply. Since cleaning and reverse osmosis reject are usually the largest consumers, water efficiency is frequently what stands between a plant and approval to expand.
How quickly can you respond to a breakdown?
Far faster at a plant we already know, because the first hours of any failure are otherwise spent establishing what is installed and where it isolates. Where response time matters, documenting the system and its isolation points in advance is worth more than any promise about mobilisation.
What should a Texas client prepare before a quote?
The process requirement, the governing framework, the site’s climate exposure including distance from the coast, the production access available, and the documentation expected at handover. Climate exposure belongs in that list here in a way it does not elsewhere, because it changes material selection and insulation detailing.
What is the commonest costly assumption in this state?
That cheap power makes energy-driven design decisions irrelevant. It reduces one cost and leaves the humidity, the corrosion environment and the capital consequences of over-ventilating entirely intact. The plants that struggle here were usually designed elsewhere and adjusted for tariff rather than for climate.
Does summer heat affect construction productivity?
Substantially on outdoor and unconditioned work, where heat stress management, rest cycles and hydration requirements reduce achievable output through the middle of the day. Projects planned on temperate-climate productivity assumptions run late in a Texas summer, and shifting heavy outdoor work to early mornings or nights is common practice.
Is night work practical on industrial sites here?
Frequently, and for summer outdoor work it is often the sensible answer, subject to lighting, supervision and any site or municipal restrictions. It also suits tie-in windows on continuous plants. The cost premium is usually less than the productivity loss from working through afternoon heat.
How does the labour market affect scheduling?
Specialist sanitary and high-purity welding capacity is committed well ahead, particularly with several large projects active in the state, so booking crews against fixed dates is the difference between a project that runs to programme and one that waits. General mechanical labour is more available than specialist capacity.
Can multiple sites be served under one arrangement?
Where a client operates several Texas facilities, combining scopes into planned campaigns reduces mobilisations and produces consistent documentation across sites, which matters when one quality system covers all of them. It also allows spares and procedures to be standardised, which is worth more than the travel saving.
What makes a Texas project run late?
Long-lead equipment ordered against an unfrozen design, permitting for emissions or discharge started too late, and summer productivity assumptions. None of them are construction problems. The projects that finish on time settle the design parameters that drive procurement and permitting first and accept detail changes afterwards.
What documentation should a multi-state client expect?
A consistent turnover package regardless of which site the work was performed at: material traceability, joint records with examination results, test data, slope and passivation records, and as-builts in one format. Clients operating across states frequently receive different packages from different regional contractors, which undermines the value of all of them.
