Improving Strömmen's water for cleaner environment and new homes.

Stockholm City and Nacka Municipality have developed a joint action program for Strömmen. This program aims to improve the water quality and habitat for animals and plants in Strömmen, which currently has unsatisfactory ecological and chemical status. The proposals include reducing pollution from sediment, traffic, and sewage, as well as improving the physical environment. The costs for these measures are estimated to be hundreds of millions of kronor for managing contaminated sediment and soil, and approximately 22 million kronor for stormwater measures. The program is a prerequisite for the city to build 140,000 new homes by 2035 while adhering to environmental quality standards.
