Rankin’s experience in the design and supervision of water and sewer systems, ranges from large rehabilitation projects in major cities, to complete design and construction of new infrastructure for new mixed use developments, as well as for peri-urban areas. Rankin has experience in the hydrogeological sector, including ground water investigations and supervision of drilling works.
Rankin has been involved in projects to upgrade the water and sewer systems in many of the major towns and cities of Zambia, including several phases of rehabilitation works in Lusaka. Rankin has also partnered with several international firms in this area, providing technical expertise in design and supervision works. Donor funded projects to institute water supply and sewer network systems in peri-urban areas in the major cities has been an area of significant focus, having successfully completed more than twenty such projects in Zambia. These consultancies are not limited to pure engineering work alone, but include community mobilization and sensitization, as well as stakeholder participation in the decision process.
Another area of focus has been the design and construction supervision of completely new water and sewer reticulation areas in private mixed use developments in the capital, as well as in new townships created for large infrastructure projects such as the Kafue Gorge Lower Hydro project. Design of water and sewer reticulation systems is carried out using the latest design software packages, with topographic survey data compiled in the field by in-house engineering teams.
Rankin is also involved in geophysical investigations, pilot and production hole drilling supervision, and design and supervision of borehole equipment. Works have been carried out for large agricultural developments, as well as commercial utility companies. Significant works have also been done for the installation of boreholes with handpumps as a means of improving access to clean water in rural areas of Zambia. Rankin also has experience in the installation of windmills.
