One of the upgraded sewerage treatment plant in Nairobi. [Jonah Onyango, Standard]

The treatment capacity at Ruai Sewerage plant in Nairobi has now shot up to 320,000 cubic litres per day, this is according to the latest update from the environment department.

For many years, the capacity had stuck at 160,000 cubic litres per day but the increase has been attributed to the expansion of the Kariobangi Sewer Treatment Plant from 30,000 cubic metres to 90,000 cubic metres per day.

The expansion was aimed at modernisating Nairobi’s sewerage network, improve environmental conservation and support the city’s rapidly growing population.
