Storm water management improved in the Ranta-Kartano area

The service consortium of the City of Lahti is currently running a project for the management of storm water with cost-effective hybrid solutions, which will significantly reduce the storm water load to Lake Vesijärvi.
Storm water elements in Rantakartano

​Uponor's experimental Rain Garden storm water elements have been installed as part of the works performed in the streets of the Ranta-Kartano area in Lahti.

The project makes use of new natural management methods, while also serving as a product development environment for storm water management and nutrient recycling solutions.

Storm water management is improved in the Ranta-Kartano area using distributed systems, such as swales and green roofs as well as infiltration and detention basins.

The development project is implemented by the city's service consortium in association with Lake Vesijärvi Foundation and the Department of Environmental Sciences of the University of Helsinki. The project is funded by the Ministry of the Environment, and it is one of the Government Programme's key projects. The project is implemented in 2016–2018.

At present, storm waters from the city centre add a considerable load to the Enonselkä basin, both in terms of nutrients and harmful heavy metals.
