Scottish Water completes £16M WTW upgrade
Scottish Water has completed a major upgrade of Muirdykes Water Treatment Works which will benefit more than 84,000 people in parts of Renfrewshire.
The utility has invested £16M in improvements at the works, which provides water for homes and businesses in Renfrewshire and south Paisley. The work involved the installation of a new filtration building and process at the WTW, near Howwood, to reduce the risk in the network of discoloured water caused by naturally-occurring manganese.
Although it is possible that localised discoloured water might occur following issues such as a burst water main, the risk of widespread discolouration throughout the network caused by manganese at Barcraigs reservoir near Howwood in the summer months has been substantially reduced following the upgrade.
The completion of the project follows investment of £4M four years ago on more than 100 miles of water mains affected by discoloured water in Renfrewshire and the installation of a Wears Resmix system at Barcraigs reservoir in 2012.
Mr Iain McMillan, Scottish Water’s senior project manager, said: “These improvements in the past few years have helped to tackle the problem of manganese and discoloured water in the Muirdykes WTW supply zone although they were unable to eliminate the risk, as we saw in August 2016 when there was discoloured water in some parts of the network.
“The completion of this most recent major investment at the WTW, and the installation of a new filtration process, will improve the robustness of our system and further reduce the risk of manganese and discoloured water in the longer-term.”
Joanna Peebles, Scottish Water’s regional community manager for the area, added: “Scottish Water aims to provide continuous clear and fresh drinking water to all our customers, wherever they live.
“While we cannot guarantee there will be no recurrence of manganese and discoloured water in the Muirdykes network, our upgrade of the WTW, in addition to the previous investment, will substantially reduce the risk and we know this will be welcomed by our customers in Renfrewshire.”
The upgrade of the WTW was carried out for Scottish Water by contractors Black & Veatch, and started in September 2015.
The new secondary stage filtration process will remove oxydised manganese from the system before it goes into the supply zone and will be housed in a single-storey building constructed on the site of the WTW.
Scottish Water had given an undertaking to the Drinking Water Quality Regulator to provide an effective manganese removal system for the area.
