Water treatment plants for long-term needs
Clean drinking water, efficient wastewater treatment and reliable water services are essential foundations of a functioning society.


Water treatment facilities are long-term, technically demanding investments where safety, quality, energy efficiency and lifecycle performance are critical considerations.
NYAB delivers water treatment plants, wastewater treatment facilities, pumping stations and other water infrastructure projects, both as new-build developments and refurbishment projects. We combine strong construction expertise, project management and technical systems integration to create comprehensive solutions that meet both current and future customer needs.
Comprehensive delivery from planning to commissioning.
With decades of experience in water infrastructure projects, we are a trusted partner for demanding water treatment developments. We work closely with municipalities, water utilities, industrial clients and infrastructure operators.
Our services cover the entire project lifecycle:
- Project development and design management
- Earthworks and ground engineering
- Foundations and concrete structures
- Process buildings and treatment facilities
- Pipeline and water distribution systems
- Pumping stations and transmission pipelines
- Process and electrical systems
- Automation and control systems
- Commissioning support and project handover
When required, we can act as the main contractor, taking full responsibility for project coordination and the integration of all disciplines.

Extensive experience in complex facilities.
Constructing water treatment facilities requires a deep understanding of both civil engineering and process industry requirements. Our projects combine large concrete structures, technically demanding equipment installations, piping systems, electrical infrastructure and automation technologies.
Our experience includes:
- Wastewater treatment plants
- Drinking water treatment facilities
- Surface water treatment plants
- Centralised treatment plants
- Pumping stations
- Hydropower facilities
- District cooling plants
- Water infrastructure projects supporting public utilities
Building solutions for the long term.
Water infrastructure must operate reliably for decades. That is why we focus on high-quality construction, cost-effective delivery solutions and safe working methods throughout every project.
Close collaboration with clients, designers and process suppliers enables controlled project execution even in demanding environments where construction often takes place alongside operating facilities or where uninterrupted water services must be maintained throughout the project.
Experience from major water infrastructure projects.
Over the years, we have delivered many water treatment and wastewater projects across Finland. Our references demonstrate our ability to execute new-build facilities, major modernisation projects and complex process construction projects in a wide range of operating environments.

Tampere central wastewater treatment plant
NYAB delivered two technically demanding wastewater pumping stations for the new Tampere regional central wastewater treatment plant, including pumping structures, tanks, maintenance facilities, control rooms and staff facilities.

Jämsä central wastewater treatment plant
NYAB constructed the extension of the Jämsä central wastewater treatment plant, delivered the new process building and carried out refurbishment and mechanical works while the existing facility remained in operation.

Valkeakoski surface water treatment plant
The Tyrynlahti surface water treatment plant produces nearly all of Valkeakoski’s drinking water. NYAB delivered the project as a turnkey contract, including a new water treatment plant, pumping stations, pipelines and process and building services systems.
A trusted partner for water infrastructure projects.
Whether the project involves a new water treatment facility, an expansion of a wastewater treatment plant or the modernisation of an existing facility, we provide strong project expertise and comprehensive delivery capabilities throughout every stage of the project.
By combining construction, infrastructure and technical systems expertise, we deliver solutions that support clean water availability, environmental objectives and the long-term functionality of society.

Questions about water treatment plants.
What types of water treatment projects does NYAB deliver?
We deliver water treatment plants, wastewater treatment facilities, surface water treatment plants, pumping stations and other water infrastructure projects. Our expertise covers both new construction and the expansion and refurbishment of existing facilities.
Can NYAB manage the entire project delivery?
Yes. We provide comprehensive project delivery, covering everything from design management and civil works to concrete structures, process facilities, technical systems and commissioning.
Can construction work be carried out while the facility remains operational?
Yes. We have experience delivering construction and refurbishment projects alongside operating facilities. Projects are carefully planned to ensure that plant operations can continue safely and without disruption throughout the construction period.
What services are included in water treatment plant construction?
Depending on the scope of the project, services may include earthworks and foundations, concrete structures, process buildings, pumping stations, pipelines, electrical and automation systems, as well as the installation of process equipment and technologies.
How do you ensure quality and safety in your projects?
Quality management and safety are integrated into every phase of the project. We follow structured HSEQ practices and maintain continuous quality control, thorough documentation and safe working methods throughout project delivery.
Why are water treatment plants an important part of society’s infrastructure?
Water treatment facilities ensure the availability of clean drinking water and the safe treatment of wastewater. They are a critical part of public infrastructure, environmental protection and sustainable water management for both current and future generations.
