Who we are


infraPLAN is a New York-based engineering boutique firm that focuses on the planning of the Rehabilitation & Replacement of water & wastewater buried linear assets.

The services provided include consulting, tool development and training. infraPLAN developed the user-friendly infraSOFT platform that assists utilities eager to conduct projects themselves.

infraPLAN has helped utilities with system length ranging from 40 to 6,000 miles.  While we pioneered the introduction in the US of analytically advanced forecasting models and planning approaches, we also propose simple solutions for small or less mature utilities.

infraPLAN is WBE-certified in NYC and NY state, as well as nationally through WBENC.


Annie Vanrenterghem Raven, Ph.D.

For the last 22 years, Annie has been helping utilities create Rehabilitation & Replacement plans for water & wastewater buried linear assets, first as a researcher at New York University, NY, NY; then through infraPLAN, a firm she created in 2008. At NYU she was the principal investigator for research projects funded by the NSF and the USEPA involving EU-funded CARE-W and CARE-S. Those allowed her to play a pioneering role in the industry and introduce advanced analytical approaches. She is a frequent speaker and participant at national conferences, workshops, and forums, and the author of numerous technical papers. She is a member of the Advisory sub-committee of AWWA's Asset Management Committee where she concentrates on innovation and data-based approaches.  Annie holds an undergraduate degree in mathematics and physics, a graduate degree in structural engineering from ESTP, Paris, France, a MPH with a concentration in environmental sciences from Columbia University, NY, NY, and a Ph.D. in civil engineering from New York University, NY, NY.
