SYSTRA has experience and expertise when it comes to designing new facilities and development areas in a long-lasting, sustainable manner that promotes long-term, sustainable infrastructure for the supply of drinking water and the management of wastewater and stormwater. SYSTRA also helps manage changes to the existing environment and adapts existing systems to ongoing societal developments to ensure that we secure vital supplies of drinking water along with the wastewater and stormwater management, which many people just take for granted. 

Water and sewage

SYSTRA’s dedicated team of water and sewage design engineers have the experience and technical knowledge to analyse and optimise a solution based on existing site constraints and the requirements for the overall project outcome. We have a wide range of reference projects and are constantly making new inroads in this area. At SYSTRA, we also work with water and sewage issues during the early stages of a project, including stormwater assessments in conjunction with design planning work and water and wastewater development assessments. 

We are proud of our ability to offer a turnkey service offering – from investigation and preliminary design to project planning, including site management and technical support during the construction phase. We work closely with our customers to understand their needs and ensure that the project meets their specific requirements.

Our goal is always to focus on efficient, sustainable solutions and designs that minimise workplace environment hazards for individuals working on the construction of the facility. We do this by collaborating with colleagues with extensive experience on the production side.


SYSTRA works on several Swedish Transport Administration (STA) projects, including turnkey road and railway projects, where specific expertise is needed for drainage, stormwater management and management of water from surrounding areas, often called dewatering. We have experienced, talented personnel who constantly work on these issues. They are familiar with STA guidance documents, dimensional calculation requirements, duct flow calculations, and stormwater system design for roads, railways etc. At SYSTRA, we have experience with assessment and design work in this area and supply memorandums, 3D models, coordination models (BIM models), drawings and technical specifications. We also carry out dewatering projects for municipalities.


For conduit coordination services, SYSTRA has a team of employees across the country who offer specific expertise for a wide variety of projects. The specific conflicts encountered are contingent on the nature of each project. SYSTRA has expertise in municipal conduit coordination of, inter alia, water and sewage, electrical, optical and remote heat conduits as well as in coordination of the railway’s signal, electrical and telecommunication systems along with intersecting ducts that come into conflict with other types of pipes.



Design of a new residential area in Kävlinge, Sweden that includes several run-off dams, multi-functional stormwater basins etc. The retention basins in the natural park primarily consist of several large depressions in the eastern end of the park. The stormwater reservoirs were designed as a dry reservoir with a small bottom outlet to slow down and purify the water before it reaches the Kävlingeån river and an overflow outlet large enough to handle a 20-year flood. In addition, the reservoir is large enough to prevent neighbouring roads from flooding in the event of a 100-year flood.

The stormwater assessment focused on naturally adaptive solutions that suit the area in and make the stormwater visible. Our assessment report proposed a wetland within an area that’s already depressed with high water levels, continued local treatment of roof water and development of the existing dike system.
