The three men - the farm’s managing director, Perry Kansagara, its general manager, Vinoj Kumar, and a local state water official, Johnson Njuguna - were charged at a magistrate’s court in the Rift Valley town of Naivasha, court documents seen by Reuters showed.
All pleaded not guilty to the charges, which as well as manslaughter included neglect of duty and failure to prepare environmental impact assessment reports for the dam.
