Braving the murky depths

Huge task: The commercial divers hard at work in Sungai Prai.

BALIK PULAU: Sungai Prai is famous for all the wrong reasons. Pig farms are known to have polluted the river, thousands of dead fish have been found floating in the water. It is teh-tarik brown, turbid and murky.

It was into these dirty waters that frogmen had to plunge and start repair work when a pipe under the river ruptured, cutting off water supply to about 200,000 homes.
