PANDAMATENGA AGRICULTURAL STORMWATER MANAGEMENT

Pandamatenga is a village in North-West District, Botswana, where we investigated a large portion of a planned farm area comprising black cotton clay soilsthat hindered stormwater management.

JG Afrika investigated possible solutions and provided recommendations for the detailed design of the stormwater channels and associated infrastructure.

Work included a detailed site visit and auguring of soils; calculating the peak discharge, as well as inflow and outflow hydrographs for each plot; and developed flow patterns and a stormwater management plan, including sizing of channels and berms.
