Water and wastewater infrastructure services
We operate across above- and below-ground infrastructure, delivering complementary services that support the full lifecycle of water and wastewater systems.
Serwent Group supports public and private infrastructure owners across the Nordics, ensuring the day-to-day operation, maintenance and long-term performance of essential systems that society depends on.
Our services cover both preventive and reactive needs – from routine maintenance and inspections to emergency response and long-term rehabilitation.
What we do
Serwent Group provides specialised services within water and wastewater infrastructure, delivered across above- and below-ground systems and throughout the full lifecycle of infrastructure assets.
Our services are organised around three complementary service areas:
Rehabilitation and relining
We deliver relining and rehabilitation services for both private and public pipe systems. By renewing existing infrastructure, we help extend asset lifespan, reduce the need for excavation and minimise disruption to surroundings.
Specialised and NoDig services
We provide specialised and trenchless services for complex environments and public infrastructure, supporting inspection, maintenance and renewal without extensive excavation.
All services are delivered with a strong focus on safety, compliance and operational reliability.
Operational and maintenance services
Our traditional services support the day-to-day operation and maintenance of water and wastewater systems, including:
- Pipe services and maintenance
- Sewer and drainage services such as inspection, cleaning and condition assessment
- Emptying and environmental services
- Inspection, testing and other specialised services
These services help prevent failures, manage risk and ensure operational continuity.
Supporting infrastructure over time
Water and wastewater systems require continuous attention over time. Through a combination of operational services, rehabilitation and specialised solutions, Serwent Group supports infrastructure owners throughout the full lifecycle of their assets.
Our approach includes:
- Preventive maintenance and inspections, reducing the risk of unplanned disruptions
- Emergency and standby services, ensuring readiness when critical situations occur
- Rehabilitation and renewal, improving system performance and extending asset lifespan
- Data-driven insights and decision support, enabling informed planning and prioritisation
This integrated approach helps infrastructure owners ensure continuity, manage risk and achieve long-term value.
Local delivery, backed by a Nordic group
Serwent Group operates through strong local teams with deep technical expertise and close customer relationships. These teams are supported by shared systems, standards and ways of working across the group.
This combination enables local responsiveness, consistent quality and scalable capacity for complex, multi-site and long-term assignments across the Nordics.
