The Environmental Protection Ministry on Sunday opened a criminal probe after a power outage caused sewage to leak into the Kishon River over the weekend in Kiryat Tivon, near Haifa.
Authorities were able to stop the leak and repair the infrastructure at the Mayanot Haemek Water Corporation waste-treatment plant on Saturday, and said sewage will remain present in the water for days to come.
An initial investigation showed the leak was caused when a water-pumping station became overworked, causing a power outage.
As a result of this outage, wastewater was able to leak out, but there was no warning system in place to alert authorities of the malfunction.
An effort is now underway to upgrade the existing system in cooperation with the Environmental Protection Ministry.
