Kenya's Principal Secretary for Internal Security and National Administration, Raymond Omollo, has announced a significant 27-kilometre sewer upgrade in Nairobi to combat the city's escalating pollution crisis along the Nairobi River.

• The project will upgrade Nairobi's aging sewerage infrastructure, designed to intercept and treat up to 60 million litres of wastewater daily.
• Key figures include Principle Secretary Raymond Omollo and the Kenyan government.
• The upgrade targets areas like Lucky Summer and Baba Dogo, aiming to divert wastewater before it pollutes the Nairobi River and residential areas, following recent tragic sewer incidents.
