If Nairobi River could speak, it would not whisper. It would roar. And what it would say might surprise us. Because the river’s story is not just about dirt and decay. Four persistent forces have choked its life for decades. These include solid waste, sewage, industrial dumping, and unplanned land use. Each one tells a truth we can’t ignore.

The first is solid waste. Mountains of textile leftovers, plastic packaging, and market debris line the riverbanks from Dagoretti to Dandora. Nairobi’s thriving mtumba trade imports over 200 million kilograms of used clothes every year. Yet, nearly 80 million kilograms are discarded for being too damaged to sell. Piled near the river, they block its flow, trap toxins, and turn every rainfall into a waste spill. Then there is sewage. Beneath the city, broken sewer trunk lines continue to leak untreated waste into the river. In some sections, these lines have been damaged for years, turning once-clear tributaries into slow-moving channels of contamination. When it rains, the overflow sweeps through nearby settlements and straight into the water system. The damage doesn’t stop there. It circles back through crops irrigated with the same polluted water. This water nourishes food that ends up on our tables every day.

Industrial waste follows next. Factories along the river’s path release chemical effluents that stain the water dark and acidic. Even after multiple warnings and compliance notices, accountability remains unclear. Every colored ripple in the current carries a question: who will take responsibility? Finally, there is unplanned land use. Settlements built along the riverbanks lack proper drainage or solid waste systems. When floods come, homes are damaged and the waste returns to the river. The cycle continues, a loop of neglect that harms both people and nature.

Together, these four forces have shaped what Nairobi River has become. It reflects systemic gaps in waste management. There are also gaps in planning and accountability. But this is not a story of despair. Through RiverLife TV, PSN and its partners are documenting what’s changing and what still needs to. River stewards stationed along the river are collecting stories, data, and evidence that reveal both progress and pain points. Their work is helping turn public awareness into public pressure and eventually, public accountability. Because clean rivers are not made by announcements. They are made by attention and action. To restore Nairobi River, we must face its truths, name its enemies, and rebuild its systems. And that starts with seeing pollution not as someone else’s problem, but as a shared responsibility.
