Freetown, Sierra Leone: Providing Improved Water Service for Urban Citizens

Over 90% of the water supply to Freetown, Sierra Leone is supplied from Guma Dam and Water Treatment Plant. But this dam was built in the 1950s-60s and can only reliably provide water to the population it was built for at that time—around 800,000. The current population of Freetown approaches 2 million. In addition, Freetown’s water distribution network has significant leakages, resulting in an estimated 40% non-revenue water (i.e., water lost between production point and the customer). Through this project, DT Global improves water service provision by supporting the Guma Valley Water Corporation in significantly rehabilitating critical water supply infrastructure across Freetown, serviced by the Guma Valley Dam. The project leads a consortium of firms, including Atkins and BAM Nuttall, on a design and build contract to deliver services across four stages: feasibility, front end engineering design, detailed design, and construction. The project was designed to focus on the most critical components of work required to rehabilitate the Freetown city water supply, while maintaining budget.
