Their job description involves cleaning sewage plants but there are times they find more than just waste.
These sewerage workers have found more than 10 foetuses within a year while cleaning the plants, Kosmo Ahad reported.
Indah Water Konsortium (IWK) Sdn Bhd senior communications manager Shahrul Nizam Sulaiman cited a case in which a maintenance worker at a sewerage plant in Kuala Lumpur found a foetus, believed to be about two months old, stuck to a wall at the plant.
Similar incidents happened at centralised plants including smaller plants that connect housing areas throughout the country, he said.
To date, there are about 6,000 sewage treatment plants nationwide maintained by Indah Water.
Shahrul Nizam said the workers who found the foetuses were traumatised by what they saw.
"Most of those foetuses were not fully formed. If there was a foetus with complete limbs, its body was often bruised and full of scratches.
"Some found only the head, or an arm or a leg," he said. The foetuses, he added, would usually get stuck along a sewerage pipe.
Shahrul Nizam said Indah Water would inform the police upon each discovery.
