Passengers were asked not to travel by road to Terminals Two and Three after access was blocked by the flood, which is understood to have been caused by a main leak.
All roads had reopened by Saturday afternoon, with the airport operating as normal, a spokesman for Heathrow said.
The burst main occurred beneath a road in the central terminal area (CTA) of the airport.
The CTA refers to an area including Terminals Two and Three, as well as a number of other buildings, connected by a network of roads.
It is understood that neither terminal was flooded and flights were not disrupted.

Flooding in the central terminal area has resulted in on-going road closures restricting access to Terminals 2 and 3. Passengers travelling to or from either of these terminals today must not travel by road.

Passengers were asked to allow extra time to complete their journeys and to use the Heathrow Express, Elizabeth Line, Piccadilly Line, or park-and-ride services at Terminals Four and Five to access Terminals Two and Three.
The disruption hit passengers amid the school summer holidays, which sees hundreds of thousands of customers pass through the airport at peak times.
A spokesman for Heathrow Airport said: “Following earlier flooding in the central terminal area impacting access to Terminals 2 and 3, all roads have now reopened and the airport continues to operate as normal.
“We apologise for any inconvenience caused and we thank passengers for following the advisories we had put in place while our teams worked to resolve the situation as quickly as possible.”
