Improvement works to two village sewer systems are set to spark 12 months of disruption on a busy Fylde road.
United Utilities is planning the work to provide the villages of Singleton and Little Singleton with better equipped systems meaning accidental incidents of raw sewage overspilling into the River Wyre should no longer happen.
Work on the scheme is set to begin in February, around the Mains Lane section of the A585.
The works are expected to last for around 12 months, although full details of any road closures or diversions have yet to be disclosed.
However, community leaders expect it to cause disruption along the extremely busy route.
Coun Maxine Chew, who represents Singleton on Fylde council, said: “The great excitement we’ve got is that in the very near future United Utilities is starting to put a new sewerage scheme in, although when they do start this work it will cause disruption on the A585. They’re doing some exploratory digging and surveying at the moment.”
A spokesman for United Utilities said: “We’re planning to start work in two locations in Little Singleton to upgrade the sewer network.
“Work is expected to start on Mains Lane (A585) in February and we will be on site for 12 months.
“This work will take place in sections under temporary traffic management.
“We will also have a presence on Garstang Road.
“The majority of our work here will take place in the grass verge, but there will be a short distance where we’ll be working in the highway.”
The work will ensure United Utilities complies with European regulations on water quality by 2015 which are aimed at cleaning up the Irish Sea.
The company previously said, in July last year, that plans for a new treatment works for Poulton would be reconsidered some time in the future when an appropriate site was identified.
The original £35m scheme for a major water treatment plant on the banks of the River Wyre were scaled back after local opposition.
The new scheme will see existing structures at the United Utilities site on Old Mains Lane, near Poulton, demolished.
They will make way for two underground tanks with a capacity to hold 13,000 cubic metres of storm water.
