The loan has been provided for an investment in water and wastewater treatment in southern Stockholm. The investment programme to be implemented during 2016–2018 amounts to SEK 204 million. The investments are split 40/60 between freshwater and wastewater. The programme includes the replacement of private sewers, the construction of sewage systems in new residential areas, and the renovation of the existing network.

Ekerövatten AB was established in 2013 with the task of providing water and wastewater services and managing pipeline networks, a wastewater treatment plant and pumping stations located in the municipality of Ekerö. The company is a 99% subsidiary of Roslagsvatten AB, which is owned by seven municipalities in the Stockholm area and is in charge of the distribution of fresh water and collection of wastewater.

Fulfilment of NIB's mandate


The demand for water and wastewater services is expected to increase by a population equivalent (PE) of around 500 annually following the continuing urbanisation of the region. Upgrading the infrastructure will improve access to sewerage services for summer cottages in the region by a PE of around 1,000. The project will enhance environmental benefits through reduced amounts of untreated wastewater.


Wastewater will be treated in a municipal wastewater treatment plant instead of small-scale treatment plants with subsequent infiltration. The change, which is compulsory for all affected households, will lead to less leakage of nutrients into Lake Mälaren and ultimately the Baltic Sea. Another important aspect concerns pathogens: the risk of transmitting pathogens decreases substantially. The absolute impact is small and impossible to quantify. Construction of sewage collection systems for new residential areas forms a necessary component of a sustainable society.

Sustainability summary

The implementation of the three sub-projects represents a low potential for negative environmental impact.
