In no later than 2027 to Utterslev Mose be transformed from being highly contaminated to be ‘good ecological quality’.
Such is the plan for Copenhagen’s largest freshwater area, who continue to suffer after decades of discharges of large quantities of wastewater.
– We would like to have a clean lake in Utterslev Mose, and it has been a long time coming, but the sooner the better, says Alex Heick, chairman at Bispebjerg Lokaludvalg, to TV 2 Lorry.
But getting there may prove long. Both the city of Copenhagen and Gladsaxe Municipality emitter, which remains untreated sewage in the marsh with the gloomy prehistory.
In 1968, Utterslev Mose in Copenhagen declared biologically dead.
After decades with the discharge of millions of gallons of untreated wastewater annually flowing into the bog up to 17 tonnes of phosphorus, it all ended one day, when a moor, as in a gigantic belch turned up and down at the bottom and the surface with a terrible stench as a result.
the nourishment which otherwise had lain shrouded in the sludge on the bottom of the bog, now came up to the surface – and the marsh of the dead.
Since there have been numerous attempts to re-establish life in the marsh, which today remains heavily contaminated and has approximately five times as high phosphorus content, as a clean lake.
The direct discharge of mechanically treated wastewater, there simply is filtered for toilet paper and the like, has long since stopped.

But by so-called overflow, where the rains bring rensningsanlæggene out of the game due to the large volume of water is being discharged untreated sewage in the marsh, which remains heavily contaminated.
It is in spite of the fact that the EU’s water framework directive in the start of the 00’s and later the Danish state has made it clear that the water in Utterslev Mose must achieve ‘good ecological quality’ by 2027.
But in spite of that the local authorities ‘ bets on spildevandsområdet seems to work, there is still a need to get pollution more to life, believe lokaludvalgene around the backcountry in the northwest corner of Copenhagen.
– We want to forward to, that we completely can avoid the overflow, ” says Ida Jørgensen, chairman of Brønshøj-Husum local committee, to TV 2 Lorry.

An access to Agency records of discharged wastewater, as the TV 2 Lorry is in possession of, shows that the amount of wastewater discharged into the Utterslev Mose in the period from 2014 to 2018, was reduced by up to 20 times.
Nevertheless, the 2018 led over 55 million litres of untreated sewage in Utterslev Mose from the citizens of the city of Copenhagen and Gladsaxe Municipality.
It helps to put put the wildlife in the lake under pressure, saith the Ida Jorgensen. It is in particular an overflow with the designation U11, that is the big culprit.
– We are in the suburbs of Brønshøj-Husum local committee real outrage over that of the overflow may be allowed to take place, because it is that Gladsaxe Municipality has the opportunity to derive the sewage, when there are some big rains, ” says Ida Jorgensen.
In the Municipality of Gladsaxe it is the water company Novafos, which handles all waste water and rainwater. Here we know the problem with overflow, but is working to improve the situation.
– specifically in relation to Utterslev Mose, it is the whole area around the Gladsaxe Idrætspark and Marielyst, where we have separate sewage and rainwater. So we have already done quite a lot for it to be better, and it has been better, but we are well aware that we are not in the goal, ” says Arne Kristensen, kommunerådgiver at Novafos, to TV 2 Lorry.
TV 2 Lorry has tried to get a comment from Engineering and environment mayor of Copenhagen, Ninna Hedeager, but on Tuesday would not have been possible.
Also, it has not been possible to get a comment from the technical and environmental administration in Copenhagen Municipality.
