Public utilities are only half of the water engineering market. Manufacturers, chip fabs, data centers, chemical plants and food processors all depend on water to operate, and they need engineers to source it, treat it, reuse it and discharge it within permit limits. For civil and environmental engineering firms, industrial water work offers a different kind of opportunity than municipal work: faster decisions, private budgets and repeat programs across multi-site companies, along with more exposure to the business cycle.
The wave of new U.S. manufacturing, from semiconductors to batteries, comes with large water requirements. Semiconductor fabs are the clearest example. TSMC’s three planned Phoenix fabs are projected to use a combined 16.4 million gallons of water per day, according to Axios. Because of on-site recycling, the city expects to supply only about 4.2 million gallons of that, and TSMC is building its own industrial water reclamation plant to make the math work.
That project shows where the engineering work sits. A new plant needs a reliable supply, pretreatment or ultrapure water systems, wastewater treatment, reuse systems and the permits that connect all of it to the local utility and the environment.
Data centers add another layer of demand. Lawrence Berkeley National Laboratory estimated that U.S. data centers consumed about 17 billion gallons of water directly for cooling in 2023, and projected that figure could double or even quadruple by 2028. Cooling water supply, treatment and discharge are increasingly part of site selection and permitting, especially in water-stressed regions.
Industrial facilities that discharge wastewater, either directly into a river or into a municipal sewer system, must meet federal effluent limits and local pretreatment requirements. PFAS is the next frontier. According to the Congressional Research Service, EPA’s 2026 regulatory agenda targeted July 2026 for proposed PFAS discharge limits for PFAS manufacturers and February 2027 for chromium electroplating facilities. These would be the first federal PFAS-specific discharge limits for any industrial category.
The ripple effect is broader than the facilities named in those rules. As municipal utilities face their own PFAS limits in drinking water, many are taking a harder look at what industrial customers send into their systems. That pressure flows back to manufacturers as sampling requirements, pretreatment upgrades and source-reduction studies.
In many regions, new industrial users can no longer assume the local utility will supply all the water they need at a predictable cost. Facilities are responding with on-site reuse, alternative sources such as reclaimed municipal wastewater, and in some cases near-zero liquid discharge systems. Each of those requires engineering, from feasibility and water balance studies to design, permitting and startup.
| Municipal utilities | Industrial clients | |
| Decision-maker | Utility staff, elected boards | Plant managers, EHS leaders, corporate engineering |
| Funding | Rates, bonds, state and federal programs | Corporate capital and operating budgets |
| Procurement | Formal, qualifications-based, often slow | Faster, relationship-driven, often under master service agreements |
| Demand driver | Aging assets and regulation | Plant investment, production growth and permits |
| Main risk | Funding delays | Business cycles and client concentration |
Industrial water work can be highly attractive, both in its own right and as a complement to municipal utility work. The chief drawback is cyclicality. When manufacturers cut capital budgets, new-plant and expansion work slows quickly. The steadier part of the industrial market is operating support: permit compliance, sampling and reporting, stormwater management, and the ongoing upgrades every plant needs, even if it’s not expanding.
For companies that serve both the industrial and municipal utility markets, there are many synergies because the technical skills overlap. These overlapping skills include treatment, hydraulics, permitting and stormwater. As an additional benefit, because the client base and funding sources of these two markets are very different, exposure to both sectors can help smooth out revenue and create a more stable business.
