A sewer blocked by a 6ft baby wipe ball has threatened to explode and engulf an entire housing estate in feces.
Residents on a housing estate in the affluent town of Guilford, Surrey, were horrified when human waste started rising up through their toilets and drains.
An inspection by sewage workers revealed that a monster blockage had formed and caused a back-log so severe that it was threatening to send torrents of poo exploding from the toilets and burying the homes knee-deep in toxic waste.
"Obviously you can smell that smell but we're having to light three or four candles as well as different sprays and bleach just to try and get it down," one resident tells Channel 5's Grime and Punishment tonight.
"We get it outside as well, it's come all the way up to the top of the drain," he continues as his children cough at the stench.
By 7pm the situation becomes critical.
Residents return home from work and start using their showers and toilets, sending water levels soaring.
Not even the team's high-power water jets can shift the blockage and in a desperate bid to avert disaster, a tanker is called in.
Arriving on the scene, supervisor George says the clog of wet wipes started forming six months ago.
"This is probably up there as one of the worst to try and clear," he says.
Thankfully, a four-inch suction hose finally manages to budge the back-up, but George warns that as long as people continue to flush wet wipes down the toilet, situations like this will happen.
"This is half the battle sometimes because it's just fat and wet wipes. They'd don't disappear," he adds.
Grime and Punishment airs tonight on Channel 5 at 8pm.
