A Smelter belonging to Chen Di Doing, a Chinese company in Chingola has spilled acid slurry into homes after its drainages burst.
The acid slurry went into nearby homes in Chikolo loop and Kankoko area.
The acid dam, whose walls are made from sand bags, collapsed early Monday morning spilling much of the slurry into the drainage leading into Twatasha stream.
The other spillage went directly into homes where residents drink water from wells.
Contractor JM and J Director George Phiri, who is working on the Twatasha-Lulamba road, has complained over the spillage.
He said he had called Zambia Environmental Agency (ZEMA) to inspect the area but AVIC quickly went with a bowser and flushed the area.
Chingola Mayor Titus Tembo was angered after finding an AVIC bowser flushing the slurry from the drainage into the stream.
Tembo, in the company of Health Inspectors from Chingola Municipal Council, directed the inspectors to immediately arrange for a public address system to warn residents not to use water from the stream.
Kankoko and Chikola Loop areas are illegal settlements which seat on land initially designed as industrial area.
