NORMAL flow of water to Mt Hagen city, Western Highlands province, is expected to return to normal today.
This follows tireless efforts by PNG Waterboard Hagen branch staff to flush out water in the storage tanks which were contaminated after someone poured engine oil into the tanks.
One of the raw water pumps started pumping water late yesterday afternoon to fill the contact tank before supplying to the town area.
With the second pump expected to start working this morning, water will return to normal today.
Two suspects were arrested and questioned by police investigators over the incident but later released yesterday. Investigations are continuing into the matter.
PNGWB branch manager Jack Moro yesterday condemned the manner in which a few individuals held the entire city at ransom by contaminating the water.
Staff had completed cleaning the chambers and the wet well (holding tank under the pump station) yesterday.
He reassured that water was only supplied to consumers after ensuring that it is clean and safe for consumption.
Guard Dog security personnel are guarding the raw water pumps and treatment plant premises.
PNGWB has appealed to consumers to boil water derived from other sources to ensure it is safe and clean for consumption.
It also called for community assistance to find the culprits who contaminated the water.
Meanwhile, a community leader in Mt Hagen has called on people living near the city to take ownership of public properties and look after them.
Michael Wamp from the Moge tribe said yesterday that destroying public property would lead to many innocent people suffering.
Mr Wamp said the contamination of the water supply clearly showed that people lack common sense and did not care about others.
“Western Highlander should be ashamed of this,” Mr Wamp said.
