After many years of operation without maintenance, the settling pools, which absorb the wastewater from the Kedmat Galil industrial area, were almost completely blocked. Laboratory results showed that the treatment process did not occur as expected and the quality of effluents did not meet regulatory requirements.
It was necessary to remove the sludge and clean the pools, while preserving the walls of the basins, the plumbing systems, the basin cover, and more. it was also important to treat the sludge in order for it to comply with regulations.
