Multiple pump failures at the Knocksedan waste water pump station led to raw sewage flowing out of it into the nearby Ward River, earlier this week.
Locals reported a stream of foul smelling water flowing downhill from Knocksedan into the river.
Responding to the reports on Monday council staff attended the scene and the overflow had stopped.
In recent weeks a pump failure occured at the station and when inspected it was discovered that a secondary pump was also close to failure. To deal with this a submersible pump was put in place powered by a generator.
At some stage over the weekend the isolation switch on the generator was turned off leading to the leak.
The council took charge of the pumping station a number of years ago. Council Officials say they hope to decommission the pumping station soon.
Cllr Ian Carey said:
“This pumping station is clearly a massive environmental risk. Simple pump failures like this should not be leading to rivers of sewage flowing into our much loved park.
“I’ll be calling on the council to redouble their efforts to end the use of this pumping station.”
