WORK will start soon to stop sewage flowing into the River Holme during bad weather.
But the work will mean shutting a road.
New storm screens are to be fitted in the sewage system under Scholes Road, outside the White Horse pub at Jackson Bridge.
They will stop sewage backing up and getting in the river during heavy rain.
The work, which starts on Monday and will last for eight weeks, is part of a £3.6m project to improve water courses in the Holmfirth area.
Part of Scholes Road will be closed. The diversion will be via Park Side Road, Paris Road, White Wells Road, Dean Bridge Lane, Butt Lane and Hepworth Road.
Steve Cooper, project manager for Yorkshire Water, who will be supervising the works, said: "The screen will retain storm and sewage debris. This will improve the quality of water entering the River Holme during storm conditions.
"We appreciate this is a busy road and apologise for any inconvenience our work may cause. But the road closure is essential."
