United Utilities have advised Blackpool households to continue boiling water as a precaution, after small levels of cryptosporidium were found in the supply.
They have issued the following information:
"The boiled water notice for parts of Lancashire is expected to remain in place until mid-week, United Utilities confirmed today (August 10).
Customers in Blackpool, Chorley, Fylde, Preston, South Ribble and Wyre are being advised to continue to boil their water as a precaution, for all drinking, food preparation and brushing of teeth.
People can continue to use tap water without boiling for general domestic purposes such as bathing, flushing toilets or washing clothes.
The advice comes after routine tests at Franklaw water treatment works in Preston detected small traces of cryptosporidium - a microscopic bug - in the water.
Traces of the bug are continuing to decrease – but the boiled water notice will not be lifted until United Utilities is absolutely confident that there are no traces left in the water network.
Gary Dixon, United Utilities customer services director said: “The picture is improving all the time, with the traces of cryptosporidium continuing to reduce.
“However, we would ask customers to bear with us, and continue to boil their water for drinking and food preparation, until we are absolutely confident that the water is back to its usual very high standards.
“We recognise how inconvenient this is for our customers, and would like thank households and businesses for their immense patience as we work to get things back to normal.”
United Utilities’ scientists are continuing to test water samples, and engineers are flushing water pipes to expedite the process.
The company continues to provide advice to customers through its website, social media, radio, TV, newspapers and websites, and has been hand-delivering leaflets to customers across the affected area."
United Utilities have a customer information centre at Morrisons on Squires Gate Lane, FY4 2AY and opening from 8am, both today and tomorrow.
