Jane Dodds told the Senedd yesterday that Llanwrtyd Wells feels "abandoned" following recent flooding.
The Mid and West Wales MS said that she visited the town over the weekend for a public meeting, to discuss the devastating impact of a recent flood.
She said the flood is coming off the trunk road.
"Just to give a bit of context, there’s a broken culvert, broken pipes throughout the village, causing significant damage," said Ms Dodds.
She explained that households were witnessing sinkholes opening up in their gardens.
One victim of the flooding told Ms Dodds how a burst pipe caused a large sinkhole to open up in their back garden, which quickly filled up with water. Tragically, the victim's pet dog fell into the hole, causing it to drown.
Speaking to Trefnydd of the Senedd, Jane Hutt MS, Ms Dodds said: "And this is obviously a very sad story, but the town actually feels abandoned. Nobody has been to see them.
“I’m liaising with the trunk road agency, but I wondered if you could also bring pressure in order for those people to have some reassurance that something is being done."
Ms Hutt urged the Senedd to think of those who have been affected in Llanwrtyd Wells.
"The impact of those recent floods you brought to life, the impact on that town, is very clear and we think of the families who have been affected, particularly the story of the sad loss of that family pet as a result of the sinkhole," she said.
Ms Hutt said that Welsh Government officials are set to meet with Llanwrtyd residents next week.
"Now, I understand there are several issues ongoing in Llanwrtyd Wells following on from the storms and local land ownership issues. So, I hope you can relay this to your constituents that we are aware of these issues, we are mindful of Llanwrtyd Wells and the impact of the floods," said Ms Hutt.
"So, the Welsh Government’s strategic road network division intends to meet with local residents next week to discuss options to resolve some of the issues, and the strategic road network division alongside their agents are investigating the cause of the opened up carriageway on the A483 and intend to carry out necessary repairs at the earliest opportunity, but I’ve also asked if our officials could meet with you, Jane, next week, to go through these issues."
Speaking outside of the session, Ms Dodds said: “Speaking to locals it was clear that they felt let down by the Welsh Government, who have so far failed to take sufficient action to help the community rebuild what was lost.
“This town, like so many across Mid Wales, feels neglected and ignored by Cardiff Bay.
“This cannot continue, the Welsh Government need to reassure residents that they will support them in not only rebuilding, but also by preventing this issue from happening again.”
