Decision Support System for Selection of Satellite versus Regional Treatment for Reuse Systems

Principal Investigator
Stephen Davis, Malcolm Pirnie, Inc.

This project develops a spreadsheet-based tool to assist utilities in comparing the advantages of constructing a satellite wastewater treatment plant for reclaimed water use and those of using a regional wastewater treatment plant, with inherent distance and elevation concerns of direct users. The flexible tool allows users to develop and apply weights to customized ranking criteria for economic and noneconomic evaluations.

The DSS consists of a customized Microsoft Excel workbook with dynamically interactive worksheets that calculate relative, planning-level costs of user-defined satellite and regional reuse system alternatives. An enhanced user interface guides the user to input data, select treatment options, define a simplified distribution system, and apply weighted decision criteria to compare the two alternatives.
