A young man and women are in intensive care after a Russian nightclub was flooded with boiling water from a nearby main, forcing party goers to flee on makeshift boats.

More than 450 people were evacuated from the 'Gold' club in Yekaterinburg, in Russia's Urals region, as the scalding deluge flooded the dance floor and car park with water over a metre deep.

Five of those evacuated were reported to be in a critical condition at the scene, and two remain in intensive care with burns to 23 per cent of their bodies, according to the Interfax news agency.

The incident occurred at around 2am on Sunday morning and, such was the volume of water, cars in the parking lot were submerged to their roofs, while the indoor temperature climbed to 40 degrees Celsius.

Clubbers were forced to climb as high as possible as the flood water reached 120cm and tables and chairs were used as makeshift life-boats. Club security was able to evacuate 150 people before the rescue team arrived and waterlogged cars were later dragged away.

"We've suffered millions of dollars of losses. However, through our insurance company, we will do our best to help the victims of the accident," the club's lawyer told website Lifenews.ru.

'Gold' club has said that it will not be suing the power company who owns the burst water main, but they will hope to negotiate compensation for the damage caused.

According to reports, the water main was recently repaired and passes all the required pressure tests; the cause of the failure will be investigated.
