10/28/2011 Distributed DBOF Water Resource Solutions Ed Clerico, CEO October 4, 2011 Water Reuse – 24 Years of DBOF Projects • Over 40 systems using direct and indirect water reuse • Residential, Commercial, Institutional, Industrial • Water Reuse of 25%-95% providing significant reduction in water and wastewater demands • Flush water, cooling, laundry, irrigation applications • Wastewater mining and centralized system load shedding2 1
10/28/2011Ridgewood, NJ- 20 Yr DBOF – Biogas/Solar Optimizing Renewable Energy via Solar + Internal and External Biosolids Carbon Heat Sources Goal = Net Zero Energy3Wetland Based Passive Treatment Mechanisms 40 Wetland Based Treatment Systems – MN and GA – Conserving Energy, Carbon Sequestration, Improving Biodiversity – Low Cost Future CSO Solutions4 2
10/28/2011How We Innovate – Creative Finance and Creative Delivery - DBOF Create via Design Build – assume risk of implementation Eliminate multiple contractor, multiple phase liability Manage via long term Operation – assume risk of functional performance Include operating functions into the design process and control ultimate performance Direct Investment – Finance – assume risk of financial performance Sponsor direct investments and funds into niche utility asset types as a blend of debt and equity, sometimes partnering with governmental agencies and funding mechanisms (PPP) NSU Water Infrastructure Profitable long-term assets that provide appropriate risk/reward profile5Why These Innovations Occurred – Innovation Drivers • Scarce resource or lack of adequate supporting infrastructure • Inadequate sustainable water supply • Overflowing or noncompliant wastewater system • Favorable economics • Property values were adequately high – cost of innovation was small (typically < 1.5% of construction) • Lower life cycle costs – superior TBL outcome • Immediate operating and capital cost benefits • Strong environmental initiatives • Green Building • Need to reduce environmental impacts6 3
10/28/2011How These Innovations Were Implemented •Entrepreneurial drive • Passion for innovation and new solutions • Willingness to take risk • Right mix of technical, functional and financial capability • Leadership • Top command establishes the mission with clarity and conviction • Organizations align and have good integrity – New York City Buildings Sustainability Board as example • Collaboration • Willing regulators and existing service providers – willing to accept change • Creative planners and developers7Responsible Management Entity as Distributed Service Provider Existing Utility/ Govt Entity Regulators Association/Co-Op/etc Services Ground Fees $ Service Fees Lease/Site Shared Savings Services RME Assets Responsible Management $ Ownership/Financing- $ Debt/Equity Entity (RME) IPP WWTP – Co-Owned by SPV Water/Energy/Nutrient Services Design Build Own/Operate Design Construction Operations Repair & Replace8 4
10/28/2011 Integrated Systems Thinking: Reuse and Regeneration System Optimization Water: Reuse ENERGY NUTRIENTS ENERGY: Renewable: Biogas Efficiency: Heat Pump WATER Efficient Source & Use: NUTRIENTS: Potable, Non-potable Primary Nutrients: NPK Efficient Treatment : Soil Addatives Biomimetic Systems (storm, waste) Efficient Total Reuse: SOLID BY-PRODUCTS: Water, energy, nutrients, solids Carbon Sources: Beneficial SOLID Reuse VEGETATION BY-PRODUCTS VEGETATION: Inedible, Edible Carbon Sequestration Biomass 9 Financially and Environmentally Superior Results Cheaper to Build, Operate and Maintain than most conventional systms: Costs40% less to build. Cuts fossil fuels by 60% . Costs 60% less to operate. Uses 50% less water. Meets 100% of water safety standards. * Operating performance based upon NSU track record, and returns, internal model.10 5
