Eight fire engines and around 60 firefighters tackled a grass fire near Stanhope Road in Rainham.
One hectare of woodland and two hectares of shrubland were alight.
Firefighters were supported at the scene by a bulk water unit, which is being piloted this summer.
Bulk water units are able to carry 8000 litres of water to incidents, allowing firefighters to tackle fires more effectively in areas where traditional water supplies are absent or ineffective, as can be the case with grass or wildfires.
London Fire Brigade is also trialling new wildfire response vehicles this summer, which have off-road capabilities and technology that allows firefighters to pump water while driving, enabling them to fight an outdoor fire more quickly and safely.
All firefighters have received enhanced training for grass fires and wildfires and a Wildfire Support Officer was also in attendance. They were deployed as a wildfire tactical advisor, providing key support to the Incident Commander. The welfare of operational crews working in hot weather conditions is a key priority and firefighters are provided with additional hydration packs, sun cream and protective headwear for personal protection on the incident ground.
Local residents are advised to continue keep windows and doors closed due to smoke travel in the area.
The Brigade was called at 1510 and the fire was under control by 1707. Crews from Barking, East Ham, Harold Hill and surrounding fire stations attended the scene.
