New rain champions to accelerate the practice of urban rainwater harvesting
International Training Network Centre of Bangladesh University of Engineering Technology (ITN-BUET) in association with WaterAid Bangladesh and International Water Association (IWA) Bangladesh organised 'International training and exposure visit on urban rainwater harvesting system' at ITN-BUET, Dhaka from 11-14 December 2022.
This year’s training had participants from diverse backgrounds – including architects, engineers, industrialists, development practitioners, and academicians. Experts and professionals from the sector including ITN-BUET, WaterAid, RAiN Forum, University of Dhaka, and IWA facilitated different sessions covering a wide array of technical and cross-cutting topics.
The participants got the opportunity to visit Mobil House, a Platinum LEED-certified commercial building who are practicing rainwater harvesting system. This exposure visit helped the participants to obtain a holistic view of the water management system including rainwater harvesting, wastewater treatment, and groundwater recharge in commercial buildings and how the system can be beneficial. It also contributed to bridge the gap between theoretical knowledge and real-life implementation of practicing rainwater harvesting system.

The participants were tasked to complete a group assignment to reflect on their learnings from this training. Each team presented their work, and the best team was awarded after evaluation. At the end of this training, on 14 December 2022, the participants were introduced to networks like RAiN Forum, IWA Bangladesh, and WaterWomen to unite and build on their knowledge. Certificates were handed over to the participants by Dr Tanvir Ahmed, Professor, Department of Civil Engineering, Bangladesh University of Engineering and Technology (BUET) and Director, ITN-BUET, and Ms Hasin Jahan, Country Director, WaterAid Bangladesh.
24 new rain champions emerged through the training who have committed to utilise their knowledge and skills in their respective fields for a better and sustainable tomorrow, where every drop of rainwater will be valued.
