Expensive repair of leaky dam waiting – Swedish Radio

One of the largest hydroelectric dams, Seitevare dam in the Lilla Lule River, delicious.

Now, Vattenfall is investigating what should be done to seal the pond. It is clear that it will cost hundreds of millions.

– Because of the weaknesses – that we get a higher leakage at higher water – we have an operating restriction. We do not use the magazine fully, just to keep the säkerhetsmarginagler we need, says Claes-Olof Fire Stone, who is dam safety manager at Vattenfall.

Keeping safety margins and not fill the hopper when the opportunity arises, make that Vattenfall can not use the magazine fully financially.

It concerns millions of dollars annually, who now drops to not be able to use all the water tray holds. So now look Waterfalls on what to do with the leaking dam.

– We are in the investigation stage right now to determine what action is best to take, says Claes-Olof Fire Stone.

It sounds like a costly project to seal such a large pond, what will it cost?

– We do not really know what it will end when we have not decided what action we must take. But it is about several hundred million, that’s for sure.
