What's with this waste pipework?

I was walking past a house of multiple occupancy the other day, there's a 45 degree coming off the vertical part of the soil pipe opening into what looks like a hopper with a mesh in it.



What are they trying to catch? Brown trout?



What's going on there? (I am a nosy bastard, yes.)


That is an utter bodge done by a clueless numpty, as also demonstrated by the inadequate fall of the two lateral pipes above it.

the Grey Y-connector is upside down !.

Send these photos to your local BCO. Give him something to do.

Original pipe blocked so divert sewage to an alternative drain?

With a filter to catch the jobbies?

It really is very bizarre.

A filter than looks a bit like the top of a swing-top kitchen bin hacked-off and munged into place.

This is a foul drain, so needs to be completely sealed apart from the vent pipe 300mm? above an opening window. Maybe this is home-brew AAV because there is no vent pipe ? Without seeing the whole stack it is difficult to say.

I am also wondering if the two pipes going into the pavement are foul drain and surface water respectively. If so whoever did this needs a bit of education.

Looking from farther back it appears that it's just the gutters and drainpipes feeding into it.

A down-pipe splitting into two like that still doesn?t make any sense though?

Tim

I wonder, because that's all i've got, is that there might be something in the Y piece sending leaves and such into the hopper on the right?
