Pemba community gets a ductile iron water pipeline for clean water

The port city of Pemba in the Cabo Delgado Province of Mozambique is receiving a gift of life with area soon to extend its clean water supply following the installation of the 42- kilometer long bulk water pipeline which will carry water into the city’s growing population. The new 500mm diameter ductile iron pipeline comes with new pump stations and expansion of the well field to double the volume of water than can be supplied to Pemba.

This project is due to be completed and handed over in August 2019 following 12 months of activity on site. Tshwane based Nyeleti Consulting Engineers is part of an international project team entrusted with delivering this project by the Mozambican government's Water Supply Investment and Assets Fund (FIPAG). Nyeleti’s services included the preliminary and detailed design of the 42km DN500 Ductile Iron Transmission Main.

Some of the major tasks that have been completed include hydraulic and surge design of the new transmission main, which determines the route and condition assessment of the existing transmission main. “This project meant that Nyeleti had to work with a diverse international team that included role players from China, Germany, Mozambique and South Africa.

The various expertise in the team ensured that the work done is always carried out with the highest professionalism. This has ensured that we continuously meet and exceed our set milestones. The pipeline will deliver clean water to the Pemba community come August 2019,” says Valize Scholtz, an Associate Engineer at Nyeleti Consulting. “Through this project, we had the opportunity to improve our design expertise in many fields for example surge analysis and condition assessment”, says Scholtz.

Even though Pemba is well renowned for being a prime destination for water sport and diving enthusiasts and has seen an increase in migration since the discovery of natural gas, the supply of clean water has been a major challenge. Scholtz adds that working with an international team is a privilege but has its fair share of challenges such communications breakdown as most of the role players were not first-language speaker of English, which is a common business language. Despite that, the Nyeleti team has been able to deliver results which have ensures that the project progress without any interruptions.

“We also encountered challenges with the route for the 42km pipeline as we found constraints with road reserve, the position of the pipe and houses that were constructed too close to the road,” says Scholtz. With several countries in the Southern African regions still grappling with serious water infrastructure challenges, Nyeleti sees its involvement in the region long after the conclusion of the Pemba project in August.

The Nyeleti team involved in this project has a collective experience of over XXX years, which some members previously involved in projects such as [CAN WE NAME PREVIOUS PROJECTS WORKED ON HERE] “Firstly, to be able to visit a beautiful city such as Pemba and working in rural areas of Africa is an honour, as this has been one of the longest bulk pipelines we have been involved in.

The challenges and opportunities to bring clean water to rural areas makes all the effort to be worth it in the end,” concludes Scholtz.
