Sci-Tek Engineer Presents Paper at the EWRI 2012 World Environmental & Water Resources Congress


May 23rd, 2012, Albuquerque, NM.  Sci-Tek Civil Engineer Kimberly Artita, PhD presented a paper at the 2012 World Environmental & Water Resources Congress Conference titled "Seeing Green by Going Green: Maximizing Ecosystem/Community Services Benefits through Strategic Green Storm-Water Infrastructure Design".  The paper was co-authored with R. Rajan of CDM Smith and J. Knighton of the Philadelphia Water Department, Office of Watersheds.

Combined sewer overflow (CSO) control in ageing urban areas is a costly and on-going issue.  In addition, urban municipalities must deal with other daunting issues such as economics, sustainability, etc.  In the paper, the authors demonstrated how decision makers might capitalize on the concept of natural capital or ecosystem services benefits as well as other economic benefits in sewer shed-scale green storm-water infrastructure (GSI) designs aimed at reducing CSO volumes.  This concept was demonstrated on a sewer shed within the City of Philadelphia using triple bottom line (TBL) estimates of benefits, continuous hydrologic/hydraulic simulations using EPA's Storm Water Management Model (SWMM) and coupled with a simple genetic algorithm (SGA).  Results were compared to existing conditions.  Also explored were situations where property values are excluded from the analysis as a method of promoting economic equity in GSI placement.

The Environmental & Water Resources Institute (EWRI) is a civil engineering specialty institute of the American Society of Civil Engineers (ASCE), the country's oldest national engineering society.  EWRI was formed to provide improved and comprehensive products and services to a variety of engineering teams working in technical, educational, and professional areas.  The EWRI's vision is to be a recognized worldwide leader within ASCE for the integration of the technical expertise and public policy in the planning, design, construction and operation of environmentally sound and sustainable infrastructure impacting air, land, and water resources.
