Water supply from Sasumua dam to Nairobi is expected to resume next week.
According to Water and Sanitation Cabinet Secretary Sicily Kariuki contractors are already at the site repairing transmission pipelines that were damaged by a landslide in Karemenu River at the Aberdare Ranges.
The dam accounts for 11.6 percent of the water supply to Nairobi.
Residents in parts of the capital city are currently experiencing water shortage worsened by great tepidity and muddy water from Ng’ethu dam which supplies about 80 percent of water to Nairobi.
Last week, section of residents of Nairobi county had to do without water for an indefinite number of days after operations at the Sasumua dam were shut down.
Nairobi City Water & Sewerage Company Ltd said it was forced to shut down water supply at the dam due to a landslide inside Aberdare forest which has damaged the water transmission pipes.
The firm said the suspension of transmission at Sasumua means 11.6 per cent of city estates and commercial centres will experience water shortage indefinitely.
Meanwhile the Ministry of Water and Sanitation has set aside 400 million shillings for construction of a major sewerage distribution system in Ol Kalou town in Nyandarua County that is expected to serve more than 30, 000 people.
