Portland Infrastructure Plan

Overview

The SUPPLY AND TRANSMISSION MODEL (STM) was created for the PORTLAND WATER BUREAU (PWB) by Dr. Richard Palmer and Margaret Hahn of the Department of Civil and Environmental Engineering of the University of Washington, with the support of David Parkinson and Sumaya Haddadin of the Bellevue office of CH2M-Hill and members of the PWB staff, Dennis Kessler, Lorna Stickel, Hossein Parandvash, Doug Bloem, Azad Mohammadi, and Joe Dvorak.  This model allows the exploration of a wide variety of water supply, water management and water transmission options that address the current and future needs of the Portland Water Bureau.  The model was created in the Stella Research 6.0.1 simulation environment and in Microsoft Excel.  The STM is a highly interactive modeling tool, allowing PWB staff to create a shared understanding of the model’s assumptions and encouraging the staff to explore how various future expansion and conservation alternatives allow the system to meet the PWB water supply and natural resource management mission.
