Dhaka, Sept 19 – Bangladesh receives on an average 1500 mm rainfall every year and this is adequate to meet most domestic needs, experts said on Thursday. They were speaking at the 4th Rainwater Harvesting Convention held at a city hotel. They also opined that by collecting rainwater for reuse and recharging fast-depleting groundwater sources, water scarcity can be reduced while increasing resilience against climate change – reducing water-logging and helping restore water-related ecosystems.
With proper design and management, Rain Water Harvesting (RWH) system can provide acceptable water quality for drinking in households and industrial uses in both rural and urban areas, said Prof Dr Tanvir Ahmed of the Department of Civil Engineering, Buet.
Rainwater harvesting is a practical, cost-effective and sustainable solution to some of the water issues that the country is currently facing, he added.
