Water and waste

Safe water and sewerage services are essential for the continued growth of cities and society in the future. Sweco's experts ensure that water and sewerage treatment systems supply clean water and they deal with the waste water discharged by millions of people each day. We have adopted an integrated approach and ensure that all the economic considerations, the environment and people are taken into account.

Pipeline engineering

Traditional trench digging and the associated removal of soil creates a negative impact on the natural environment and vulnerable vegetation. The risk of incurring leaks and discharges is reduced when clients prioritise correctly and select satisfactory solutions for the renovation of pipeline systems.

Sweco helps by developing water and sewerage renovation plans and undertakes planning and design work for all types of pipeline systems. We also resolve various challenges relating to large transfer systems and the connection of shared water supplies across municipal boundaries.

We employ environment-friendly NoDig/ trenchless methods when this produces the best results. Our experts employ various techniques, i.e. lining sewerage pipes, bursting existing water and sewerage pipes and the insertion of new pipes, or the installation of new pipes using directional drilling. For more simple installations, such as crossing pipes, we press pipes into loose soil or drill into the bedrock.
