The UK’s largest outfall pipe has been laid under the sea at Anchorsholme.
Water firm United Utilities said it 'believed to be the largest single man-made structure ever to have been transported across the UK'.
Altogether 14 boats were involved in transporting and placing the pipe in a specially dug trench off the coast.
More than 100 people were involved in its transportation, which took four years of planning, the company said.
"The superpipe will help prevent flooding, along with helping to protect Blackpool’s Blue Flag beach by transporting excess surface water two miles out to sea after big storms," a spokesman said.
