Raw sewage has been flowing down a central Wellington street. Wellington had a more serious sewage spill in January after a wastewater pipe burst (file picture). Photo: RNZ / Samuel Rillstone Wellington City Council spokesperson Richard McLean said it was a relatively small flow cause by a pipe blockage. "It's a small overflow, I mean it's absolutely disgusting and I've seen some video and footage of it and it's not something you want to see when you've just had your lunch but, you know, we're working on it." He said events like this did happen from time to time and it was probably caused by a mini fatburg or tissues.
