He's passionate about providing optimized solutions to utilities, especially on large climate resilience and gray-green infrastructure planning projects.

Nitin’s experience spans the whole water modeling gamut— including watershed assessments requiring hydrology and hydraulics, evaluation studies for combined sewer overflows/sanitary sewer overflows, point and non-point source pollution allocation, and large infrastructure planning and performance evaluation.

Having worked on major projects with a significant impact on protecting water resources and infrastructure across the U.S., Nitin serves on national committees with the Water Environment Federation to help set industry standards. As a recognized leader in the field of water modeling, he took on the role of vice-chair for the production of a WEF comprehensive modeling manual called “Stormwater, Watershed, and Receiving Water Quality Modeling.”
