The family called in the help of Michael Sehr of the Professional Animal Rescue Rhein-Neckar.
Sehr immediately informed a friend from the local fire brigade, who also came to the scene with seven firefighters.
At least eight firefighters encircled the manhole, taking in the animal's pitiful plight.
The chunky rodent had to be rescued by firefighters.
The stricken rodent was freed on Sunday afternoon after residents in the German town of Bensheim, around 35 miles south of Frankfurt, spotted the rat in its predicament.
Berufstierrettung Rhein Neckar, an animal rescue organization from Rhein Neckar in southwestern Germany, was involved in the rat's rescue.
The reason the situation is getting so much attention is probably because even in the face of adversity, the rat looked ridiculously cute.
But for now the rat, * a href="https://www.facebook.com/TierrettungRheinNeckar/?tn-str=k*F" *which Rhein-Neckar says was unharmed, has lived to see another day and, along with the good work of its rescuers, has been lighting up the Internet.
Mr Sehr said: "When the manhole cover was completely raised, I was able to free the rat with a twisting motion".
The animal rescue group learned about the stuck rat after a young girl noticed the creature in distress, the BBC reported.
Footage of the rescue shared on the animal rescue team's Facebook page prompted hundreds of comments, with many thanking the men for helping an animal many consider to be vermin. He said that the chubby rat had lots of "winter fat" on its body.
