This includes supporting the Pune city government towards the Swachh Bharat Mission, conceptualizing and supervising the development of USAID-Reckitt’s joint Hygiene Index initiative in India, developing the Blue & Green Master Plan for Bhopal city, structuring Haryana state’s cluster-based solid waste management infrastructure, and developing the water policy for Gujarat state. Additionally, Mr. Chatterjee was routinely engaged in management and the development of high-value and strategic bids for these organizations and their team building.
