Drain 1 is a drain for the guttering, rain water.
Drain 2 is just a surface drain for rainwater
HOWEVER
at some point, before my dad got the house (which is an old house), the previous owners had installed a dishwasher and washing machine and literally piped the waste from this through a hole in the wall and down a pipe into this surface drain. It is at the opposite end of the kitchen from the sink and proper waste pipe.
