While the drying climate in the West drives utilities to find alternative water supplies, and increasing environmental restrictions in the East limit options for disposal, water reuse will play an increasingly critical role in the management of water resources.
Helping Utilities Understand and Achieve Reuse
Hazen’s engineers and scientists have advanced reuse practices through research, innovative design, integrated water planning, support for regulatory development, and operational support. We understand the additional rigor that is required for potable reuse. We have led the industry's use of the Hazard Analysis and Critical Control Point (HACCP) method for safeguarding water quality for direct potable reuse. We have also developed and delivered operational training for advanced treatment processes.
“Our bold ideas are anchored in reality. We work to push the boundaries of advanced water treatment to help utilities achieve the highest level of public health protection without locking themselves into solutions they can’t afford. We don’t just prove that technologies work—we prove that they work in the real world under real constraints.”
— Gaya Ram Mohan, Hazen’s Director of Advanced Water Treatment
Regulatory Guidance
Reuse regulations must safeguard the protection of public health and the environment while empowering water managers to effectively navigate requirements and achieve long-term water goals. Hazen is at the forefront of supporting the development of these practical, approachable water reuse regulations across the U.S.

Program Planning and Management
Implementing a reuse program can be complex. Hazen’s reuse strategists can help chart your roadmap to building a lasting, successful program with governance modeling, project management, stakeholder alignment, funding support, and Owner Advisor services that bring clarity and confidence from concept through commissioning.
Facility and Treatment Design
Reuse facility and advanced water treatment design must address both big-picture considerations and day-to-day realities. Hazen’s holistic design approach is helping utilities achieve their water quality goals and regulatory compliance while also positioning them for long-term adaptability and program success.
Operations
Designing with the operator in mind elevates the safety and sustainability of reuse facilities—and thereby reuse initiatives as a whole. Hazen’s emphasis on incorporating a boots-on-the-ground perspective while educating and empowering reuse professionals is a recognized hallmark of our reuse work.

Communications
Engaging the public and key stakeholders early and often is vital to reuse program success. Hazen helps utilities build strong foundations for reuse support with tailored community education and outreach.

We don’t just prove that technologies work—we prove that they work in the real world under real constraints.”
Hazen’s deep bench of reuse experts utilize a full range of advanced water treatment technologies to support clients’ needs, including:
- Membrane technologies (including reverse osmosis and nanofiltration)
- Advanced oxidation processes
- Biological filtration (including membrane bioreactors)
- Carbon adsorption
- Chemical systems (including ion exchange)
- Ultraviolet light
“The projects our clients are planning today will define the next era of water security, and they’ll depend as much on transparency and trust as they will on technology. We’re investing in research, innovation, and collaboration to create solutions that empower utilities to build technically rigorous reuse systems that will earn trust, adapt to change, and protect public health.”
— Kati Bell, Hazen’s Global Director of Innovation and Technology
