2nd phase of LOTUS-HR launched in New Delhi

The second phase of an Indo-Dutch project called Local Treatment of Urban Sewage Streams for Healthy Reuse, or LOTUS-HR was launched at Barapullah drain in New Delhi by Minister of Science and Technology Harsh Vardhan and the Dutch Royal couple, Netherlands King Willem-Alexander and Queen Maxima.

The Dutch Royal couple is on a five-day visit to India at the invitation of President Ram Nath Kovind. This trip will be King Willem-Alexander’s first state visit to India following his ascension to the throne in 2013. The visit is expected to boost political and economic cooperation between two countries.
