The former Liberty X singer wrote on her blog about the terrible accident, warning readers “to never assume a manhole is safe.”
The mum of two was panic stricken after she realised Faith had gone from her sight while at a friends home at the weekend.
“I turned to check on AJ and as I turned back, after what must've only been a second, Faith had gone,” she wrote for OK!.
“I shrieked: "Faith" so loudly AJ burst into tears and Faith whaled (SIC) which I recognised as a cry for help. She was at the bottom of the hole!
“Thankfully, two builders ran over. One of them lowered himself into the hole while the other supported him so they could fetch Faith and I couldn't be more grateful.
“She was covered head-to-toe in sewage, AJ was in floods of tears and all I wanted to do was to hold her but I had to check she was OK first.”
Luckily, Faith was unharmed apart from “smelling worse than one of AJ’s nappies”.
Poor love.
