Sustainability is no longer a secondary consideration in the water & wastewater sector. It is now a defining force that is actively reshaping how companies structure their teams, prioritize skills, and compete for talent in an increasingly complex global market.
As regulatory pressure intensifies and environmental expectations continue to rise, water companies are being forced to rethink not only how they operate, but who they hire to deliver long-term impact. This shift is accelerating demand for those professionals who can combine technical expertise with environmental awareness, strategic thinking, and digital capability.
For employers and candidates alike, understanding how sustainability is influencing hiring is critical to staying competitive in 2026 and beyond.
Sustainability is redefining hiring across the water sector by increasing demand for ESG expertise, embedding environmental responsibility into traditional roles, and elevating the importance of long-term, impact-driven thinking in recruitment decisions.
The water sector is no longer centered solely on infrastructure delivery and operational performance. Sustainability is now embedded across planning, design, delivery, and long-term asset management, which is fundamentally changing the nature of many roles.
Professionals are expected to operate with a broader perspective that includes environmental impact, regulatory alignment, and resource efficiency, alongside their core technical responsibilities.
Roles evolving fastest include:
At the same time, established roles such as civil engineers and treatment specialists are expanding to include responsibilities related to carbon reduction, water reuse, and nature-based solutions, which makes sustainability a core competency rather than a specialist discipline.
According to UNESCO, women and men across water-related sectors support over 3.2 billion jobs globally, reinforcing both the scale and importance of the workforce required to deliver sustainable water systems.
ESG has moved beyond compliance and is now shaping strategic priorities across the water industry. Businesses are under increasing pressure to demonstrate measurable progress, which is directly influencing how they hire.
Companies are prioritizing professionals who can:
This shift is reinforced by investor expectations. According to PwC, more than 80 percent of investors now consider ESG factors in their decision-making, including how companies manage environmental impact and workforce diversity.
At a leadership level, sustainability is no longer treated as a standalone function. It is becoming a core component of decision-making, which is changing the profile of senior hires across the sector.
Demand for sustainability-focused talent is accelerating, but supply is not keeping pace.
Water Online has highlighted growing workforce and skills challenges across the water sector, driven by an ageing workforce, increasing infrastructure demands, and the need for new technical and environmental capabilities.
This imbalance is creating a highly competitive hiring environment, particularly for roles that require a combination of technical, environmental, and digital expertise.
The most in-demand capabilities include:
What does this mean for the market? Many teams are struggling to find candidates who meet all requirements, which is forcing a shift toward more flexible hiring strategies that prioritize potential, adaptability, and transferable skills.
While sustainability has become central to the future of the water industry, the sector’s credibility is increasingly being tested, particularly in the United States, where regulatory scrutiny, environmental incidents, and public accountability are intensifying.
A number of high-profile cases have exposed systemic challenges in water and wastewater management, highlighting the gap between sustainability commitments and operational delivery.
One of the most widely cited examples is the Flint water crisis, where failures in water treatment and regulatory oversight led to widespread lead contamination, impacting thousands of residents and causing long-term public health consequences. While this was a municipal failure rather than a private utility issue, it fundamentally reshaped public trust in water systems and regulatory accountability across the US.
More recently, the US Environmental Protection Agency has taken enforcement action against multiple municipalities and utilities for violations of the Clean Water Act, including failures to prevent sewage overflows and maintain ageing infrastructure. In some cases, these actions have resulted in multi-million-dollar settlements and mandated infrastructure upgrades, reinforcing the scale of investment required to meet environmental standards.
At the same time, PFAS contamination has emerged as one of the most significant and complex challenges facing the sector. PFAS compounds have been detected in drinking water supplies across numerous states, leading to increased litigation, regulatory pressure, and public concern. In 2024, the EPA introduced new national drinking water standards that significantly reduce acceptable PFAS levels, requiring utilities to implement advanced treatment solutions and more rigorous monitoring.
Large-scale legal actions, including lawsuits against chemical manufacturers and water providers, further highlight the financial and reputational risks associated with emerging contaminants, as well as the long-term implications for the industry.
This combination of legacy infrastructure challenges, regulatory enforcement, and emerging environmental risks is fundamentally reshaping how sustainability is perceived across the US water sector.
So, what does this mean for hiring managers? Sustainability is no longer a long-term ambition or a positioning exercise. It is a regulatory requirement, a reputational risk, and an operational priority that demands immediate and sustained attention.
The water industry is under increasing pressure to demonstrate not only that they have sustainability strategies in place, but that they have the technical expertise, leadership capability, and governance structures required to deliver them effectively in a highly regulated and closely scrutinized environment.
For hiring leaders, these challenges are reshaping expectations.
Organizations are no longer hiring sustainability professionals to demonstrate intent. They are hiring to:
This requires a more advanced and multidisciplinary talent profile.
Professionals must combine technical expertise with regulatory understanding, risk management capability, and the ability to operate within highly scrutinized environments.
The Market Reality We Have Seen
Candidates are also becoming more selective. High-quality professionals are increasingly choosing to work at companies that can demonstrate genuine sustainability commitment, rather than those responding reactively to external pressure.
Sustainability and digital transformation are closely interconnected and increasingly delivered through the same initiatives.
Technologies such as real-time monitoring, predictive analytics, and smart infrastructure are enabling reduced water loss, improved efficiency, and optimized resource use, all of which contribute directly to sustainability outcomes.
These technologies can reduce water consumption by measurable margins and improve energy efficiency across systems, reinforcing the need for professionals who can connect technical delivery with environmental impact.
This is creating demand for individuals who can operate across engineering, data, and sustainability disciplines within a single role.
Candidate expectations are changing. Professionals are placing greater emphasis on purpose, impact, and long-term relevance when evaluating opportunities.
If you can clearly demonstrate sustainability outcomes that are significantly better positioned than competitors, you’re more likely to to attract and retain talent.
This is particularly important in a market where trust and credibility are under such intense scrutiny.
Our Hiring insight
“ We are seeing a clear divide. Organizations with strong sustainability positioning are attracting higher-quality candidates more efficiently, while those with weaker reputations are facing longer hiring cycles and increased competition for talent. Henry Brown, Senior Consultant, Water & Wastewater Division”
Sustainability challenges are global in nature, and the talent required to address them is increasingly distributed across international markets.
Hiring strategies are expanding to access global expertise, while maintaining the local knowledge required to operate effectively within specific regulatory and environmental contexts.
Balancing global capability with local understanding remains a critical factor in successful hiring strategies. That’s where international businesses like ourselves help clients win.
Hiring in the water sector has shifted from a transactional process to a strategic function that directly impacts the ability to deliver regulatory, environmental, and commercial objectives. As roles become more interdisciplinary and the talent pool becomes more constrained, teams must rethink how they identify, engage, and secure the right expertise.
A more proactive and consultative approach is now essential.
This means moving beyond reactive hiring cycles and building long-term talent pipelines that anticipate future needs rather than respond to immediate gaps. Engaging candidates earlier, investing in relationships, and maintaining visibility within the talent market are significantly better positioned to secure high-demand professionals.
It also requires a more nuanced understanding of what candidates are looking for.
To compete effectively, hiring teams need to take a far more deliberate and strategic approach to talent acquisition.
The reality is that demand for sustainability-led skill sets now exceed supply across much of the water sector. This is particularly true for roles that sit at the intersection of engineering, environmental science, and regulatory compliance. As a result,those that rely on traditional hiring methods are consistently falling behind.

To attract and retain sustainability-focused professionals, the following needs to focused on:
Candidates in this space are increasingly sophisticated and well-informed. They are not responding to high-level messaging or generic ESG statements.
They want to understand:
If you can clearly articulate your sustainability performance, backed by data and real-world initiatives, you’re significantly more attractive to high-quality candidates.
The most in-demand professionals are rarely active in the market, and those who are often do not meet every traditional requirement listed in a job description.
Leading companies are shifting away from rigid criteria and instead prioritizing:
This is particularly important in sustainability roles, where the required skill sets are still evolving and often do not follow a linear career path.
Relying solely on external hiring is no longer a sustainable strategy.
