Nordic Investment Bank (NIB) and the Swedish municipality of Strängnäs have signed a 25-year framework loan agreement of SEK 280 million (USD 32.88 million) to finance its investment programme for wastewater infrastructure improvements.

The uncommitted credit facility has been provided for the Municipality of Strängnäs’ investment programme for wastewater infrastructure projects between 2020 and 2024.

The investments will ensure optimum economic use of existing infrastructure and sufficient flexibility for future needs by the expansion and upgrading of the wastewater treatment and biogas production in Strängnäs.

The projects include closing the old and inefficient Mariefred sewage treatment plant, the upgrading and expansion of the central Strängnäs sewage treatment plant, and a sewage pipeline to connect the two localities. There are also large investments in the expansion and improvement of the existing pipeline network.

With a population of 36,544 inhabitants at the end of 2019, Strängnäs is one of the oldest towns in the County of Södermanland, located on the shores of Lake Mälaren in eastern Sweden.

The total investment cost for the projects is SEK 561.6 million (USD 65.96 million).
