Smelly and discoloured water will hopefully be a thing of the past for a brook in Westhoughton.
Pennington Brook, which runs from Church Street to Dobb Brow and into Daisy Hill had suffered from the problem for a year.
Councillor David Wilkinson raised the issue with the Environment Agency who have since investigated what the cause is.
David said: “A food company on Wingates Industrial Estate had connected a foul water drain into a surface water drain, which resulted in brightly coloured water and an awful stink.”
