The deluge that hit Griffith on Sunday might have created havoc with the city's drainage systems, but the rain was so welcome it barely mattered.

Yambil Street again copped the worst of the flooding, with cars and the occasional brave pedestrian having to plough through monstrous puddles.

While the flood waters presented more of an inconvenience than a major disaster for the street's businesses, long-suffering owners will be counting down the days until council begins its major drainage overhaul courtesy of a $1.8 million interest-free loan from the State Government.

Palla Street was another to feel the brunt of the storm, with a giant pool of water threatening to swallow cars whole.

Griffith City Council's general manager Peter Brooks said the flooding in some areas was exacerbated by the outdated practice of designing roads to serve as flood ways.

"From some of the designs going back to the earlier years, the roads are actually the floodway," Mr Brooks said.

"So, it's actually designed that the water will flood down the road to stop flooding the houses."

Mr Brooks said council was continually working on a flood mitigation strategy to identify the highest priority areas.

He said he hoped flooding in Yambil Street would be a thing of the past when the new drainage system is in place, which would allow council to turn its attention to other flood-prone areas.

Palla Street residents will be hoping their street will be next on the list, with a blocked drain causing water to build up on the road way.

One resident, who did not wish to be named, described it "as an accident waiting to happen" due to the water being so deep the spray completely covered passing cars' windshields.
