Four fire engines and around 21 firefighters were called to a burst water main on Kingston Road in Wimbledon today.
The road flooded between Southey Road and Merton High Street and people were advised to avoid the area while crews worked with Thames Water to reduce the water level.
Station Manager Chris Brown who was at the scene said: "Initially the road had flooded to a depth of about half a metre but crews worked hard to pump away water throughout the afternoon and early intervention by the Brigade helped to limit any damage. Firefighters also sand bagged properties to protect them and checked on local residents to see if they needed any help."
The Brigade was called at 1119 and handed the incident over to Thames Water at 1821. Crews from Mitcham, Wandsworth, Tooting and Sutton fire stations attended the incident.
Local traffic management measures are still in place so motorists are advised to check before travelling.
