The Controls Engineering Crunch: How the Water Sector's Talent War Is Reshaping Consultancy
Retiring experts, fierce competition, and a $21.85B consulting market are colliding — and the industry isn't ready.
- The water and wastewater sector faces a deepening controls engineering talent shortage driven by mass retirements, rapid technology adoption, and insufficient pipeline of specialised candidates.
- Consultancies are emerging as both a solution and a competitor — absorbing displaced talent while bidding against utilities and operators for the same shrinking pool of engineers.
- The global water and waste management consulting services market is projected to reach $21.85 billion by 2029, intensifying the race to secure and retain technical expertise.
A Sector in Transformation — and Under Pressure
The water and wastewater industry is at an inflection point. Unprecedented infrastructure investment, accelerating technology adoption, and sweeping demographic shifts are converging to create one of the most challenging hiring environments the sector has ever faced. Employers — from municipal utilities to private operators — are competing for a narrowing pool of engineers who understand not just civil infrastructure, but the increasingly complex controls and automation systems that underpin modern water treatment.
Controls engineers occupy a particularly critical niche. Their work spans SCADA systems, programmable logic controllers, instrumentation, and process automation — skills that sit at the intersection of electrical engineering, software, and domain-specific water process knowledge. This combination is rare, and the pipeline producing it has not kept pace with demand. As the sector digitises and regulators raise the bar on compliance and data management, the value of these specialists has never been higher — nor has the competition to hire them.
The U.S. water workforce was estimated at roughly half a million workers as of 2018, a figure that excluded many trades and consultants. Even that baseline is now under strain, with retirements accelerating and entry-level recruitment struggling to compensate. The result is a structural gap that shows no sign of closing on its own.
The Retirement Wave and the Generalist Gap
A significant driver of the current shortage is demographic. Many of the sector's most experienced controls and process engineers are approaching or have already reached retirement age, taking decades of institutional knowledge with them. As organisations that manage water operations in-house face dwindling specialised expertise, many are being forced to hire generalists who require substantial additional guidance to navigate the complexities of water and wastewater treatment — a stopgap that carries real operational and compliance risk.
This dynamic is particularly acute in controls engineering, where the learning curve is steep and mistakes can have immediate consequences for public health and environmental compliance. A generalist electrical engineer, however capable, is not a substitute for someone who understands the interplay between a treatment plant's biological processes and its automation architecture. The knowledge gap is not simply about credentials — it is about years of applied, site-specific experience that cannot be quickly replicated.
The American Society of Civil Engineers and the National Governors Association have both recognised the urgency of engineering workforce challenges, convening practitioners to identify actionable approaches for private industry and public sector infrastructure groups. Yet translating policy recommendations into a functioning talent pipeline remains a slow process, and the market is not waiting.
Consultancies: Rescuers or Rivals?
Engineering consultancies have stepped into the breach, offering outsourced solutions to utilities and operators who can no longer staff critical functions internally. This model has genuine appeal: it allows organisations to access specialist controls expertise on demand, without the overhead of full-time employment or the risk of losing a single point of failure to retirement. The talent shortage, paradoxically, is good for the consulting market — and the numbers reflect this, with the global water and waste management consulting services sector forecast to grow at 5.3% annually through 2029.
But consultancies are not simply service providers operating in a separate lane. They are active competitors in the same talent market as their clients. A controls engineer who might have spent a career at a utility or an operator now has compelling reasons to join a consultancy — broader project variety, stronger career progression, and often superior compensation. This creates a feedback loop: as utilities lose engineers to consultancies, they become more dependent on those same consultancies, which in turn drives further demand for the engineers consultancies are competing to hire.
For consultancy leaders, this dynamic presents both opportunity and existential risk. Winning work is increasingly contingent on demonstrating bench depth in controls and automation — a capability that is genuinely scarce. Firms that can attract and retain controls engineers will be positioned to capture a disproportionate share of a growing market. Those that cannot will find themselves unable to deliver on commitments, damaging client relationships and reputation in a sector where trust is everything.
Is It Really a Shortage — or a Storytelling Failure?
Not everyone accepts the talent shortage narrative at face value. Some recruiters and industry observers argue that the water and wastewater sector's real problem is not a lack of qualified engineers, but a failure to communicate why the sector is a compelling place to build a career. The industry is often described in terms of its challenges — aging infrastructure, regulatory burden, public scrutiny — rather than its genuine attractions: mission-driven work, job security, technological complexity, and the tangible impact of keeping communities safe.
Controls engineering in water and wastewater is, by any objective measure, intellectually demanding and socially significant work. Yet the sector has historically struggled to compete with the narrative appeal of technology companies, energy firms, or advanced manufacturing when recruiting early-career engineers. If the pipeline is thin, part of the explanation may lie in how the industry presents itself to graduates and career-changers, not just in the structural economics of supply and demand.
This distinction matters for consultancies in particular. Firms that invest in employer branding — articulating a clear and honest value proposition for controls engineers — may find that the talent pool is less depleted than the conventional wisdom suggests. Recruitment in this space is competitive primarily because of the skills shortage, but competitive recruitment strategies, mentorship programmes, and clear career pathways can meaningfully shift the odds in a firm's favour.
What to Watch
- Whether infrastructure investment programmes translate into funded headcount at utilities — or simply drive more outsourcing to consultancies, further tightening the shared talent pool.
- The pace at which automation and AI-assisted SCADA tools reduce the per-project demand for senior controls engineers, potentially easing — or reshaping — the shortage.
- Consolidation among water and wastewater consultancies as larger firms acquire smaller specialists to secure controls engineering bench strength rather than recruit into a competitive market.
