This powerpoint presentation begins by providing a brief overview of the City of Abilene's water distribution system. Model development and calibration is presented and covers the following topics: physical model; demand allocation; field testing; operational controls; and, EPS Calibration. Information on IDSE Compliance is provided, along with the development of a Capital Improvements Plan. Lessons learned include the following: verify/survey tank elevations; recognize deficiencies in wholesale customer data; small tanks are difficult to calibrate; check water ages at all tanks to ensure repeating patterns; demand allocation to all non-facility nodes is important in water age modeling; maximize existing infrastructure in CIP Planning; and, the model can be used for a variety of applications. Includes tables, figures.
