A Word From Our Managing Director

Eng. Manyangu Seni Nkiriti, Managing Director

Eng. Manyangu Seni Nkiriti

Managing Director
For three decades we have built DON CONSULT around one commitment: engineering that actually serves people. From dam safety and bulk water transmission to sanitation, roads and environmental assessment, our work is measured by the communities that get reliable water and safe infrastructure at the end of it. We bring internationally recognised standards, modern survey and design tools, and a full-time team of registered professionals to every assignment we accept.

DON CONSULT LTD was founded in 1995 by a group of Tanzanian engineers, among them Eng. Sechu and Eng. Gwimile, whose vision continues to shape the firm today.
