Flooded Garden

Sorry for the delay

I have added 3 pictures one showing the water area, the other down side of the house, where the white pipe is that is where the bathroom is there are no outside waste pipes they all seem to be internal

The last pictures is of the only drain at the back of the house

 

The property is semi detached and the gutters all end on my neighbourd house that is the same for every house in the close,

The property was built about 1990 i think

My bathroom is upstairs to the side and kitchen at the front
