Work will begin soon on a major upgrade of a water treatment works which will benefit more than 84,000 people in Renfrewshire.
Scottish Water will invest £16 million in improvements at the Muirdykes treatment works, close to Howwood.
The works supply areas including Johnstone, Howwood, Linwood, Elderslie, Kilbarchan, Quarrelton, Craigend and parts of south Paisley such as Glenburn and Foxbar.
Scottish Water invested £4m in improvements to more than 100 miles of water mains affected by discoloured water in Renfrewshire two years ago and installed a cutting edge piece of equipment at Barcraigs reservoir near Howwood in 2012.
The upgrade will involve the installation of a new filtration building and process at the treatment works near Howwood and will reduce the risk of discoloured water caused by naturally-occurring manganese.
The upgrade will be carried out for Scottish Water by contractors Black & Veatch and will start on about 1st September and is expected to be completed in the summer of 2017.
Scottish Water say there will not be any disruptions to normal water supplies.
