Ms.Annie Vanrenterghem-Raven, PhD, is the Owner and Managing Director of infraPLAN, a NYC-based firm she created in 2008 that helps water utilities create Asset Management programs. The goal is to, ultimately, identify and justify long-term investments, and select short-term projects based on risk. Prior to starting infraPLAN she was an Associate Research Professor at NYU School of Engineering working closely with EU-based research labs. For the last 18 years, Ms. Raven’s research and consulting work has focused on advanced analytical approaches, allowing utilities to use and analyze their own data and create plans that are therefore analytical, risk-based and utility-specific. Ms Raven’s undergraduate education is in Math and Physics; she holds a Master’s degree in Structural Eng. from ESTP, Paris, France; an MPH in Environmental Sciences from Columbia U, and a PhD in Civil Eng. from NYU. She is a member of AWWA’s AM Committee where she chairs the abstract sub-committee.

Mr. Kurt Vause’s experience includes 15 years public service as the Engineering Director of Anchorage, Alaska Water and Wastewater Utility (AWWU) where he was responsible for AWWU’s capital construction program, Strategic Asset Services and Planning. He supervises 37 professional and technical staff. Prior to joining AWWU, Mr. Vause spent 19 years as a Consulting Civil and Environmental Engineer. Mr. Vause served as a Board Director of WEF, and international scientific, educational and professional organization of water and wastewater professionals with 36,000 members worldwide, Alaska Section Director of AWWA, a non-profit scientific and educational organization dedicated to public health and safe drinking water with over 50,000 members world-wide.  Currently, Mr. Vause serves:on AWWA’s Water Utility Council (WUC), on AWWA’s governing council for national legislative and regulatory affairs associated with drinking water issues (regulatory Sub-committee Chair), on a project steering committee member for the 2012 IWA/Water Supply Association of Australia Asset Management Benchmarking & Improvements Project and as AWWA’s Asset Management Committee Vice Chair.

Résumé de la conférence

How much money do I need for the next 20 years? What projects should I conduct first?
The management of water systems linear and buried assets, and answer to those typical questions rely nowadays on a combination of:

  • analytical approaches using utility failure and pipe data (a lot of data; cheap; statistical evaluation) 
  • non-destructive pipe inspection (more expensive; can-not be done on whole system because of cost; non-destructive)
  • sample lab analyses mostly of corrosion and wall integrity (even more expensive; smaller length of pipes can be analyzed; destructive; requires open and cut; specific and precise results for each coupon) 

In this presentation we will focus on the analytical component of an AM program. It typically includes:

  • failure analysis and forecasting using statistical modelling
  • physical condition analysis and forecasting using statistical modelling
  • long term planning using probabilistic simulations
  • short term prioritization based on risk
  • economic optimization of replacement decisions 

More particularly we will review the resources needed to conduct that type of studies in terms of:

  • data 
  • tools to analyze that data including low cost software and algorithms
  • external support 
  • internal capacity
  • level of effort (time and money) 

The case study of Anchorage Water and Wastewater Utility (AWWU) will be presented by its Director. AWWU has built a world-class program in a very cost efficient way by:

  • leveraging existing operation tools such as GIS and hydraulic model
  • training utility personnel
  • relying on external consulting to a minimum

Other models of advanced analytical asset management programs effectively in place at other US will be shown offering options that can work for various types and sizes of utilities with a wide array of resources and constraints.
