2 Overview Water-Energy-Air-Materials-Biodiversity are intrinsically linked components of sustainability Success requires Innovation Systems and Technology Functionality Data collection and Long Term Performance Assessment Value Proposition Rewards via incentives Penalties via compliance enforcement Integrated infrastructure systems approach produces the paradigm shift required to achieve desired moon shot goals

3 Systems Segregation and Fragmentation Creates Inadequate Function Linear Segmented Approach Adds energy at each step Depletes resources on supply side Energy Stuff Community Energy Solid Waste Contaminates environment on disposal side

4 Functional System Integration to Achieve Higher Sustainability Levels Integrated Systems Reduce and Reuse Nonpotable Water Reuse Add less energy at each step and extract energy post consumer use Use less natural resources on production side Energy Stuff Natural Resource Recycling Community Energy Solid Waste Release less contaminants to environment on post consumer side Nutrient Recycling

9 Copyright Ed Clerico, 2007 Logic The quintessential dual flush toilet What s in Your Tank? If given the choice would you flush your toilet with bottled water? So why is this our current standard? Logic will ultimately prevail

10 Our Current Perspective Dates to 500 BC The Roman Goddess of the sewers, Cloacina, carried wastes to the river - so began our modern perspective on waste management - dilution is the solution. So begin the tragedy of the water commons (Garrett Hardin, Science, December 13, 1968 in reference to William Forster Lloyd 1833)
