Water company United Utilities are warning residents of Preston to not drink tap water today after contaminated water was found at a treatment plant.
The company is currently advising customers in parts of Lancashire, including Preston to boil any water they use for drinking, food preparation or brushing their teeth as a precaution until further notice.
Franklaw Water Treatment works in Preston do routine checks of the plants and have detected traces of cryptosporidium. Cryptosporidium is a microscopic parasite which can cause sickness and diarrhoea.
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 company is currently monitoring water supplies and is hoping to be able to solve the problem as soon as possible.
Residents can continue to use tap water without boiling for general domestic purposes such as bathing, flushing toilets or washing clothes.
