Today’s cities have an unavoidable impact on the environment, but adverse effects can be minimised. Sweco’s water and environmental specialists work with reducing harmful emissions, recycling waste and ensuring access to clean water. We also offer solutions that reduce climate impact and adapt society to a changed climate.

Contaminated land and emission modelling

When the land use of the built environment changes, the possible contamination of the soil must be assessed. Sweco’s experts will help you review the soil’s current condition and, if necessary, plan the cost-efficient decontamination solutions, without forgetting worksite supervision. In connection to the environmental permit procedure, we carry out basic condition reviews of soil and groundwater for directive departments. Our groundwater reviews include groundwater pipe installations, sampling and result reports.

Industrial operations and traffic release emissions into the air. Whether we are dealing with an industrial plant, waste treatment plant, wastewater treatment plant, energy production, biorefinery or traffic, Sweco has the strong engineering competence and software skills for the mathematical modelling of emissions and their spreading. We use the AERMOD software to model the spreading of nitrogen, particles, odours and other emissions. For modelling industrial and traffic noise, we use the CadnaA software.
