Northumbria Water staff used a laptop showing the sewage layout to work out where the babies had got into it — and how far the mother had walked after them.
They fell into the system at the Three Mile Inn in Gosforth and were swept along the Great North Road before going beneath two schools divided by the Metro line.
They were then washed below a sports field, a hospital and an estate before ending up under the manhole in Barrasford Close.
The mother and ducklings were taken to a nearby pond. Link -via Arbroath
