Use the Cost Effectiveness Analysis (CEA) Tool to help guide decision making on an appropriate methods of conservation program implementation. The tool is series of MS Excel spreadsheets that evaluate a one-year investment in implementation compared to the benefits in lifetime water savings. This “return on investment” approach is useful to understand the basic business case for the various Programmatic BMPs, Flex Track and annual savings towards Gallon Per Capita Per Day (GPCD) targets as the compliance approaches for the current CUWCC MOU (as of June 2011).
The CE spreadsheets are updated from past CUWCC spreadsheets that evaluate the old (pre-2008) BMPs one at a time. The past and current methodology is based on the approach developed from worksheets within American Water Works Association (AWWA) Pacific Northwest Section publication, Water Conservation Handbook, 1993 authored by Bill Maddaus and others and recently republished as Water Conservation For Small and Medium Utilities (AWWA, 2010).
The CUWCC is providing both a blank template and a basic example.
