When I first started working in a tall building overlooking the Mersey I noticed some distinctive ships with grey decks sailing up and down the river and I wondered what they were
I was told they were "the poo boats" - but this is Liverpool - believing everything people say is risky!
anyway - turned out that they were right - the transported "untreated sewage" out to sea and dumped it in specific places
When I was off shore sailing from the Wirral - the furthest buoy we sailing round was labelled "sewer"
It was considered best to NOT fall in near that one
the term "Mersey Goldfish" was in common use amoung the boats crews as well
all that has stopped due to regulations
and people still talk about "The Good Old Days"!!!!
Mersey Goldfish referred to used condoms that floated around. As kids we got used to swimming in the Mersey with them floating around us.
