70's kids drama featuring underground sewers

 Can anybody help fill in the details of a programme I'm sketchy about, all I seem to recall is that it was a victorian period piece, featured a series of dark, underwater sewers and I think there was a young urchin boy who was in it. I also think there may have been a cotton mill where children where forced to undertake dangerous work. Sounds like a thoroughly depressing programme now but I remember it being scary.

Hi Splange

I think the programme you remember might be the the series based on the book by Joan Aiken called Midnight Is A Place.

It was about a couple of orphans and their involvement in a carpet factory.The dangerous equipment in the factory maims and kills the adults and children who work there. The boy orphan Lucas at one point has a job picking rubbish out of the sewers. The story showed the grim side of life back then and was often spooky.
