An investigation into water resources at a fire in Paddington that destroyed two homes has concluded there was enough resources and water pressure available to firefighters.

Fire broke out in a Warmington Street home in the early hours of September 4 before a neighbouring house also caught fire.

Witnesses at the scene said Firefighters ran out of water at one stage and that the pressure was inadequate to fight the initial fire and the secondary fire later.

But an investigation by Queensland Urban Utilities, the statutory body responsible for delivering water, has found the water flow at the scene of the fire exceeded requirements.
