Nairobi Governor Mike Sonko has so far shut down over 25 factories that were found to be in violation of the law by dumping waste into the Nairobi river.
The governor was accompanied by several other government agencies including NEMA during the exercise.
Giloil was one such company that is based in industrial that was closed after they were found to be redirecting untreated water back into the Nairobi River.
Governor Sonko, who has been on a mission to restore the image of the Nairobi river, stated that he will not back down in the fight for a cleaner and healthier city.
The county, under its beautification program, has undertaken the effort of cleaning up the river in a bid to return it to its former glory.
In the process, NEMA officials were full of praise for the governor's efforts in tidying up the city and ensuring the factories within the county adhere to the set regulations.
Recently past, more and more factories have been shut down in the country over the same allegations.
In Machakos County, Governor Alfred Mutua shut down a company owned by a Chinese businessman for redirecting raw sewerage into Athi river.
Water Resources Management Authority chairman Joe Mutambo shut down another Chinese-owned company in Thika lacking licences related to the usage of river water.
The Chinese businessman was also accused of redirecting raw sewerage into the Chania river.
