In May VEI specialist Ton Ebbing visited Maputo to support FIPAG and Águas da região de Maputo to assess the potential for ground water abstraction and formulate concrete steps for supervision of drilling works. The visit was related to the implementation of several emergency plans to fight the drought in Maputo, as the main reservoir (Pequenos Lebombos) does not supply enough water to produce drinking water for the whole greater Maputo area. This is due to prolonged droughts in the Umbeluzi catchment (North Swaziland). One of the measures is to drill 46 new boreholes and reactivate several small, borehole fed, water supply systems. To keep boreholes operational for many years (in the whole of Mozambique) it is utmost important to frequently measure dynamic and static ground water levels. This information is important to determine cleaning actions of the filters. Also, the pump location and pump capacity is important to avoid burning motors as well as under/over pumping. Furthermore Ton Ebbing visited some damaged boreholes in Xai Xai and recommended some practical interventions to save these boreholes from collapsing. Lessons learnt and recommendations will be included in a Manual shortly.
