I am now an expert in non-revenue water in water and wastewater company in Iran. I started with irrigation engineering from university and graduated bachelor's degree in 2007. I continued in civil engineering- hydraulic structures as master degree. My work was on another branch, operation of water distribution networks and the controlling losses. I have done one project of water pressure management last year with watergems. As I was interested in, I started learning Watergems and use it in my work. I am still a student and like to learn more.
