Rainwater harvesting describes decentralised water management system that can be installed in houses, institutions and communities. This lecture slides introduce the different components of rainwater harvesting systems (for a thematic overview and possible measures for rural and urban areas, see also precipitation harvesting).

Water harvesting has been practiced successfully for millennia in parts of the world – and some recent interventions have also had significant local impact. Yet water harvesting’s potential remains largely unknown, unacknowledged and unappreciated. These guidelines cover a wide span of technologies from large-scale floodwater spreading to practices that collect and store water from household compounds.
