Nairobi County Chief Officer for Citizen Engagement and Customer Service Geoffrey Mosiria has raised concern over the worsening pollution of the KIU River in Kahawa Sukari, warning that the once-clean waterway has been reduced to a shadow of its former self due to raw sewage and illegal waste dumping.
In a social media statement shared on Monday, August 3, 2026, Mosiria lamented how the river has transformed over the past decade, saying it was once a clean waterway where residents could swim and fish.
Reflecting on the river’s past, he said that more than 10 years ago, KIU River was a vibrant ecosystem that served the local community. However, he noted that its current condition is a shadow of what it once was.
“Over 10 years ago, we used to swim and fish in this KIU River in Kahawa Sukari. Sadly, its current state is just a shadow of its former self,” Mosiria said.
He noted that the level of pollution has reached alarming levels, claiming that raw sewage flowing into the river now appears to outweigh the water itself.
“Today, the amount of raw sewage flowing into the river is even greater than the water itself,” he added.
Landlords and residents blamed
Mosiria blamed some landlords for illegally diverting raw sewage into the river, saying their actions have significantly contributed to the degradation of the waterway.
He also criticised residents who dump household waste into the river without considering the environmental consequences.
“The river has deteriorated terribly. Some landlords have illegally directed raw sewage into it, while some residents have turned it into a dumping site, disposing of household waste directly into the river without considering the devastating impact on our environment,” he stated.
According to the county official, the continued pollution threatens aquatic life, degrades the ecosystem and poses a risk to the health of nearby communities.
Call for collective action
Mosiria urged both the government and members of the public to work together to restore the river before the damage becomes irreversible
“We must urgently come together, the government and citizens, to conserve our aquatic ecosystems by stopping illegal sewage discharge, disposing of waste responsibly, restoring our rivers, and holding polluters accountable,” Mosiria urged.
He stressed that safeguarding rivers is not only about protecting the environment but also about securing essential natural resources for future generations.
“Protecting our rivers is not just an environmental responsibility; it is a duty to future generations. If we fail to act today, we risk losing these precious natural resources forever,” he added.
Additionally, Mosiria called on every Kenyan to take responsibility for protecting the environment and preserving the country’s rivers.
“A clean river is a healthy community. Let us all play our part in restoring the KIU River,” he urged.
