A workshop, which is organized by Central Environmental Authority (CEA) and Board of Investment (BOI) Sri Lanka in conjunction with World Wetlands Day 2023 , was held at 23 rd of February 2023, at MAS Holdings Auditorium at Board Of Investments Pallekale . APN project was invited for that event to share the knowledge of application of wetland concept as a water quality improvement application. I would like to express my special thanks to Professor K.B.S.N.Jinadasa, who delivered the keynote speech entitled “Importance of Natural Wetlands, and the Technology of Application of constructed Wetlands to treat wastewater”. Accordingly we conducted a field visit for the school students . I hope this would be a good contribution from our APN project for the initiatives.
