Integrated Infrastructure• Optimizing Existing Infrastructure

• Building New Regenerative Systems

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

Water Conservation / Guidelines & Standards

Status Quo - meet regulation

Green –exceed regulation

Sustainable – address future needs

Regenerative – restore function

The quintessential dual flush toilet – What’s in Your Tank?

Logic

• If given the choice would you flush your toilet with bottled water?

• So why is this our current standard?

• Logic will ultimately prevail

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)

Recent NYC Water and Sewer Rates

• Construct tanks as integral part of foundation walls to economize –concrete represents approximately 35% of costs

• $45/GPD capacity for small system of 25,000 GPD = $1 M

• $21/GPD capacity for medium system of 300,000 GPD = $6.3 M

• $16/GPD capacity for larger system of 500,000 GPD = $8 M

• Includes concrete tanks, start-up and 6 months operations

•Other Costs Factors

•Distribution System

•Stormwater treatment, storage and interconnection
