A multi-million pound scheme is under way to improve tap water for thousands of Huddersfield people.
Yorkshire Water has embarked on a project to “flush” clean 120km of the town’s water pipe network.
The aim is to improve the taste and appearance of tap water by reducing the presence of natural mineral deposits that can stick to the inner lining of old cast iron pipes and can cause discoloured water to come out of taps.
The work in Huddersfield is part of a £13.5m programme that will involve cleaning large swathes of the company’s 31,000km pipe network across Yorkshire.
Yorkshire Water technicians will systematically operate valves on water mains in thousands of streets across the region – enabling water to be flushed through the pipes at high speed, which stirs up and removes any historic deposits.
David Stevenson, head of water distribution at Yorkshire Water, said: “Our mission is to provide water to people that is clean and safe to drink.
“Drinking water quality within Yorkshire is already excellent with 99.95% of around 500,000 water tests we carried out in the last year meeting the stringent standards set by the Drinking Water Inspectorate.
“However, this project will improve water quality even further.”
Yorkshire Water said no road closures will be required and only a few days will be spent in each area, causing little disruption. Letters will also be sent to all residents in advance of flushing works being carried out on their street to provide further advice and information.
Mr Stevenson added: “Whilst the flushing takes place it may cause a slight change in the colour of tap water for a couple of hours. Any discolouration can be solved by running the kitchen tap until the water runs clear and can be consumed.”
Yorkshire Water’s 31,000km of pipework includes section of cast iron pipes dating from the Victorian era and lead pipes. The company is in the process of replacing hundreds of lead pipes with modern plastic ones to ensure it continues to exceed water quality regulations.
