Stormwater also threatens to pollute the lakes and waterways into which it flows. Sub-actions Stormwater planning in Enköping municipality Enköping is one of […]
Environmental pollutants

Environmental pollutants in surface water can be derived from today’s industries and households, but are also a result of old emissions and polluted land. These toxins are often long-lived and spread easily in our waters. Hazardous substances from factories, stormwater, toxic antifouling paints, landfills, and wastewater negatively affect water quality. Some substances, such as TBT, […]
Free fish migration

Connectivity, i.e. the ability of fish and other aquatic animals to move freely in a waterway, is a prerequisite for achieving good water status under the EU Water Framework Directive. Fish and other aquatic animals need flowing water to survive and reproduce. But many of Sweden’s natural rapids have disappeared. Our waterways have been dammed […]
Internal loading

Eutrophication occurs when a body of water becomes oversaturated with nutrients. In lakes and many coastal waters, the main culprit behind eutrophication is the nutrient phosphorus, from for example water treatment plant or agricultural emissions, stormwater, or individual sewers. These emissions can cause a great deal of phosphorus to accumulate in the bottom sediment. When […]

More than 75 percent of our coastal waters and around a third of the district’s lakes and waterways have been assessed to be clearly affected by eutrophication. Eutrophication is mainly caused by phosphorus and nitrogen from agriculture, stormwater, and […]
