Ramboll has more than 50 years of experience providing innovative water and wastewater treatment solutions. Our clients include water and wastewater utilities, governments, local and regional authorities, developers and construction companies, as well as industrial companies and international political and financial institutions. 

We advise and assist clients on a global scale with all aspects of water and wastewater treatment, including industrial wastewater, landfill leachates and program management, as well as assistance with operations & maintenance. Our technical services also provide for cost-effective and sustainable design and operation of treatment systems in the face of increasingly stringent external and internal performance expectations.

Wastewater treatment

Ensuring the quality of water requires a constant focus on wastewater discharge and well-functioning wastewater treatment plants.

We provide focused and comprehensive services for wastewater treatment and facilities. These services include solutions associated with enhanced nutrient removal; advanced wastewater treatment and biosolids management; wet weather management; asset renewal; expert consulting on the latest treatment technologies and techniques and regulatory developments (e.g., emerging contaminants including PFAS); and overall master planning.

Our key expertise covers treatment process modeling (e.g., GPS-X, BioWin, PetWin, Sumo), preliminary engineering, and layout and detailed design within biological, chemical and physical wastewater treatment plant process design. We can provide both new facilities and plant modernization in areas such as nutrient removal and tertiary treatment; sludge treatment; anaerobic digestion including co-digestion and waste-to-energy; sustainable sludge disposal; and air emissions management including odor control and air dispersion modeling and emissions modeling (e.g., ToxChem). 

In addition, Ramboll operates a fabrication facility that manufactures equipment, tankage, packaged treatment systems and pilots for clients. We also perform control systems integration, SCADA programming and other instrumentation and control work, including the fabrication of control panels for self-performed installation projects.

Technology selection & engineering 

We offer comprehensive bench-scale, pilot-scale and full-scale investigations to select the most appropriate water and wastewater treatment technologies. Our approach combines master planning, source control and technology evaluation and selection to generate the most cost-effective process design for a specific application. 

Sludge treatment, handling organic waste and reducing emissions and pollution 

Ramboll is among the forerunners within sludge and organic waste treatment. We can advise on how to use organic matter to produce biogas and thus reduce climate gas emissions, and how to reduce odor and pollution in matter. By combining this expertise within our wastewater, energy and polluted soil and groundwater services, we provide a complete solution for clients. 

Program management

Ramboll provides program management services for private- and public-sector clients, including major utilities across the US. Our experts help our clients to plan, manage, design and implement various aspects of their water and wastewater systems, as well as respond to operational emergencies. For the public-sector, these program management services include owner’s agent for collaborative delivery (design-build) projects and third-party construction management.

Operations & maintenance 

Ramboll’s operations & maintenance (O&M) solutions provide reliable operation and systematic maintenance backed by world-class technical expertise – reducing risk and assuring clients that their facilities are running properly and efficiently so they can focus on their core business. We contract operate private and industrial wastewater treatment systems and have public-sector operators and laboratory technicians available for consultation, troubleshooting and performance optimization. 

Our in-house resources make up an operations team of trained, licensed operators and project managers, a dedicated maintenance team of specialized engineers, and a skilled technical support team of wastewater treatment experts and certified laboratory professionals with experience operating environmental and industrial treatment facilities. This expertise extends to bench- and pilot-scale testing and evaluations before full-scale changes are employed. Combined, our teams provide quality, safe and sustainable O&M services tailored to client needs, including training and on-call operations assistance.


Collaboration ensures Ramboll yet another prestigious project win

Ramboll has won two projects at the US Military Academy in West Point, New York. The aim is to help American Water upgrade water and wastewater systems.
