How can we ensure that knowledge and funds are available  Management must be decentralised but with higher level support to ensure sustainability  Selection of core network requires collaboration between communities and higher levels of government  Construction should involve community to train local enterprises, inject wages, instil sense of ownership, and train for maintenance  Maintenance should be by local small firms or individuals, managed locally, and quality supervised by an elected user committee  All this requires initial and followup training for managers, technicians and local firms: (expensive and risky: sustainability of structures will require continuous higher level support)
