He added that the Karimenu II project included construction of a Sh70 million litre water treatment plant, laying of a 67 km raw and treated water transmission pipelines to Ruiru, Juja and Nairobi and is expected to serve one million people.
“Currently the project is at 95 percent completion and is expected to be finished by next month,” he added.
