Rainwater harvesting system (RWHS) provides a cost-effective and practical nature-based solution to address the emerging water crisis caused by climate change and rapid population growth in urban contexts, academicians and WASH experts told a programme.

They also said that 'Bangladesh National Water Policy 1999' recognises rainwater as the third water source. In urban areas, rainwater can be used for other non-potable purposes such as flushing toilets, watering gardens, washing cars, which can reduce dependence on existing water supply sources. This can also cut pressure on urban drainage systems caused by rainwater and waterlogging.

They made the observations at the inauguration of a four-day training on 'Urban Rainwater Harvesting System' on Sudnay jointly organised by International Training Network Centre (ITN-BUET), International Water Association (Bangladesh Chapter) and WaterAid Bangladesh. The training will conclude on 14 December.
