Integrated Infrastructure
• Progression from water/wastewater to
water reuse to energy/water (CHP) to
water/energy (heat pump cooling/heating)
to carbon conversion to biogas
• Some aspects are not new and existed in
times of scarcity
• Some aspects are completely new –
technology that allows high performance
at small scale
Simple Logic
• Why do we produce
potable water to carry our
waste?
Copyright Ed Clerico, 2007
• Why do we light and
ventilate unoccupied
rooms?
• Why do we produce
energy from scarce
resources, and in a
manner whereby much is
discarded?
The key is finding affordable effective systems and practices that
fit each specific case
Ecology as
Infrastructure
Carriage Farm
educed impervious cover
educe water demand 43%
rganic land management – integrated
st management
lter surface water runoff
roundwater recharge at preexisting
nditions
mproved biodiversity
ocal food production
• 46% lower energy consumption
• Ground source heat pump
• Natural ventilation
• Daylighting
• 85% waste landfill diversion
• Recycled content and resource
reuse
• Indoor air quality –low voc, high
filtration

Linear vs. Integrated Systems
Segregated Systems Approach Is
Not Sustainable

General Benefits of Decentralized Systems
 “Just-In-Time, Just-The-Right-Size” service delivered
without excess capital - built to exact customer needs
and specifications
 Innovation oriented – allow change with each project
 Competitive – allow for competitive systems and service
mechanisms
 High Efficiency – capture benefits of reuse, shorter
distances, less energy input, less consumption, less
waste
 Low security risk due to smaller size and greater
dispersion
Benefits of Decentralized Water Systems
Avoid undesirable secondary impacts (i.e. sprawl),
yet allow modern planned development concepts
Conducive to “Smart Growth” and “Low Impact
Development” concepts that incorporate stormwater
reuse, groundwater recharge and integrated water
resource management
Provide higher quality effluent that has nutrients
removed – simply because it has to be acceptable for
reuse
Eliminate infiltration and inflow conditions that are
readily addressed in small systems
 Capture embedded energy that would typically
dissipate into the sewers and earth

What’s Up Next
• Combination fire suppression and nonpotable water
distribution – reduce water distribution costs
dramatically while improving fire distribution
operations
• Anaerobic digestion of biosolids and green waste
• Anaerobic treatment via AMBR
• Nutrient capture and reuse
Societal Benefits
• Flexibility – not being tied to rigid centralized
system limitations- ability to integrate multiple
systems
• Improved standard of living – lower mean household
income devoted to water resource management
• Security - Lower risk associated with drought, floods
and catastrophic events
• Well being – better environmental protection and
lower health risks
We must not complacently accept the problems associated
with traditional infrastructure when better solutions
already exist.
