Prof. Harsha Ratnaweera, who is the Scientific Coordinator of WaSo Project from Norway, delivered guest lecture at the Faculty of Engineering. The lecture was on “Introduction to water and wastewater treatment” and it was held on 26th July 2017. This was very well attended by the students as targeted. This was one of the most important requirement especially in this region of the country where shortage of water is heavily reported and wastewater treatment is important. This lecture gave excellent knowledge from the senior experience professor with solid background. This lecture was organized by the students’ society with the support of WaSo project. This is to give wider knowledge to support the Civil Engineering Students studies in related subjects taught in semester 4.
