Integrating a “Green” Score into an Economic Model Used in Asset Management for Water & Wastewater Utilities
Abstract:A “green” score method for asset management is presented which encompasses short-term and long-term economics, risk of asset failure, and long-term environmental impact.
The concepts in this paper are built upon recent EPA Region 3 workshops which introduced a spreadsheet model to project 20-year expenditures based on economics and risk of asset failure. Adding a “green” score to the spreadsheet rankings changes the asset management decision paradigm from strictly economical to include both economical and environmental considerations. This allows one to capture items that are more difficult to represent by cash numbers such as environmental sustainability and quality of life factors.
