Filtration as the Missing Link in Sustainable Rainwater Programs
Rainwater harvesting is increasingly promoted across South Asia as a low-cost, climate-resilient response to urban water stress, groundwater depletion, and erratic monsoon patterns. However, many systems underperform or fail because designers treat filtration as an afterthought rather than a core design element. Poor or absent filtration leads to clogged infrastructure, contaminated storage, higher maintenance costs, and health risks—especially when harvested water is used for domestic purposes. Finally, creating confusion skepticism to practice rainwater harvesting for consumption, leading to misinformation that harvested rainwater is not suitable.
Practitioners, planners, and community implementers need practical, context-appropriate knowledge to select, install, and maintain filtration systems that match water quality to intended end uses.
SARNET webinar 23 aims to build awareness of the importance of incorporating contextually appropriate filtration systems when harvesting rainwater for consumption.

How will you address misconceptions about the safety of rainwater
Lingering misconceptions among officials and professionals about the safety of rainwater for drinking can be an obstacle to wider acceptance. Many are unaware that well-designed rainwater harvesting systems can provide safe drinking water, especially in areas with poor groundwater quality.

UAE Embassy Award Recognizes the Contribution of Empowering School Children on Climate Change Adaptation with Rainwater Harvesting by Lanka Rainwater Harvesting Forum
In celebration of the UAE’s 54th National Day, the UAE Embassy Water Award 2025 was presented on December 10 to exceptional Sri Lankan champions who enhance water security, climate resilience, and community wellbeing. This initiative, launched by the UAE Embassy in Sri Lanka with support from the International Water Management Institute (IWMI), honors individuals and groups whose impactful work in research, advocacy, journalism, and community action has significantly influenced Sri Lanka’s water landscape.
One notable recipient was the Lanka Rainwater Harvesting Forum for their project, “Empowering School Children on Climate Change Adaptation with Rainwater Harvesting.” This initiative has transformed over 5,700 students into climate-resilient water champions through hands-on training and the establishment of more than 200 school-based rainwater systems, providing safe drinking water and fostering lasting behavioral change.

Women and girls suffer most from the impact of the climate crisis
Therefore, they travel longer distances such as from Himalaya Darchula to the Mahakali River to fetch water for their families. Governments must multiply investments into the UN water ambition for 2030 (SDG6) to help more than half of the world’s population have clean water and better adapt to the climate crisis.
