Prestonians are being urged to boil their water before drinking it, preparing food or brushing their teeth.
AdvertisementUnited Utilities have issued the warning after tests at the Franklaw water treatment works in Preston found traces of cryptosporidium.
Friday morning update: Boil water warning remains in force
The company says the traces are low but have issued the advice, which covers the whole of Preston, Wyre, Fylde, South Ribble, Chorley and Blackpool with immediate effect.
People can continue to use tap water without boiling for domestic purposes such as bathing, flushing toilets or washing clothes.
Martin Padley, Chief Scientific Officer at United Utilities, said: “The advice is being given purely as a precautionary measure as we carry out additional tests today.
“We apologise for the inconvenience but the health of our customers is absolutely paramount.”
The boil water warning is to remain in force for Thursday evening and into Friday morning.
Customers are asked to take extreme care when boiling water because of the danger of scalding. Simply bring water to the boil and let it cool.
United Utilities is monitoring water supplies and is hoping to be able to lift the boil water advice as soon as possible. Here’s what customers have been asking on Twitter.
