Kedah Menteri Besar Muhammad Sanusi Md Nor joked that he will dam up Sungai Muda and redirect its waters away from Penang.

This is if Penang doesn't pay a raw water bill it owes Kedah, he said.

"We will redirect Sungai Muda somewhere else... where will you (Penang) get your water from then?

"I can ask the villagers to put sandbags to dam the river at Pinang Tunggal.

"That's our last intake. After it's all dry you go catch fish (with your hands) at Sungai Pulau Pinang," he said.
