Firefighters rescued an elderly man trapped in a deep sewer in southern China.

The video was filmed in the city of Liuzhou in Guangxi Zhuang Autonomous Region on October 17.

Rescue workers had assessed the situation, discovering an 84-year-old man lying roughly 13 metres from the mouth of a pipe within a 3.5-metre deep well. With a diameter of about 0.4 metres, the tight space meant that they couldn't reach him directly. While the elderly man was responsive, he was immobilised and evidently in a fragile state.

Unable to access him through the sewer, firefighters swiftly coordinated with a nearby construction unit, summoning an excavator to the scene for an emergency rescue operation.

Upon further inquiries with the family, it was revealed that the elderly man suffered from Alzheimer's disease. Tragically, he had been missing for three days since October 14.

Despite the family's desperate pleas and reports to the police, the elderly man remained missing until they received the fateful call from the authorities.

The elderly man was rescued and his vital signs were stable. He was promptly transported to a hospital for further treatment.

广西柳州市柳北区
有市民称在石碑坪镇209国道路段下水道内
听到有一老人呼救
需要救助，情况危急……

上午8时01分，救援人员下井观察后发现，井深约3.5米，下水管道口径约0.4米，老人呈躺卧状态，距管道口13米左右。被发现时，老人仍有意识回话，但无力动弹。由于无法从下水道进入救援，消防人员紧急联系附近施工单位，调派挖掘机到场进行协助救援。

经询问老人家属得知，老人今年84岁，患有阿尔茨海默病，于3天前（10月14日）离家外出后一直未归。家人报警查找一直无果，直到接到警方电话，才得知老人被困在下水道中。经查看公共视频得知，老人于14日下午5时许，独自走到掉落位置附近区域，老人被困处离他家大约2公里远。

目前，被困老人生命体征正常，已送至医院救治。
