United Utilities is investing £15 million to improve the water quality on a stretch of the River Roch.

The water company will be undertaking two projects at Openshaw Park and James Street to help provide storm flow screening and help mitigate against the impact its operations have.
The company is holding a public event at Openshaw Park tomorrow - United Utilities is hosting a drop in session tomorrow so members of the public can find out more about the schemes.
For the project in Openshaw Park, sections of the park will be closed off to the public for up to 12 months to allow for the works to take place.
Both projects are expected to start later this year, subject to planning permission.
The drop in session will take place between 3pm and 7pm on Tuesday 23 May at the bowling club at Openshaw Park, Pimhole Road, Bury, BL9 7EY.
United Utilities said it will work closely with the local council and community groups to ensure that disruption is kept to a minimum and that there is still access to a number of facilities for park users.
Following the completion of the projects, areas used for construction will be returned to their previous state.
The company recently revealed that is has been able to successfully bring forward £900 million of investment in the next two years to help tackle storm overflows and improve river health right across the North West.
