WATER AS A DRIVER FOR INNOVATION: Water Utilities Perspective
2
Issues Facing Water Utilities
Regulatory Requirements
Water Availability
Population Growth and Shift
Climate Change and Drought
Aging Infrastructure and Water Loss
Economic Restrictions
Future Sustainability
3
Basic Concepts To Fuel Innovation and R&D
Water is a renewable resource
Wastewater is a source of green, renewable energy
Alternatives: Desalination and Water Reuse
Should All Water Be Treated to Drinking Water Quality?
4
Water Reuse
West Basin Municipal Water District
Five types of recycled water
5
Water Reuse
Orange County Groundwater Replenishment System Planned indirect potable reuse
Solaire Luxury Apartments, Battery Park NY In building reuse
Gillette Stadium, Foxboro MA In building reuse
6
Alternative Resources - Desalination
West Basin Seawater Desalination
Demonstration Facility, Redondo
Beach, CA Ocean Water
Haverstraw Water Supply Pilot Project
Rockland County, NY Hudson River
Melbourne, Australia Desalination
Ocean Water
7
Wastewater as a Source of Green, Renewable Energy
Target Objectives Satisfy Treatment Quality Objectives
Limiting the Environmental Footprint
Improving Energy Efficiency
Diversification of Energy Sources
Green Energy Sales
Self Sustainable Operations
Eco-conceptual Plant Designs

Where are the highest value areas?
– Current Leak detection / lost water efforts occurs with out much guidance of where to look first.
Automated Metering Infrastructure pilot
Uses real time data to focus leaks location efforts
– Incorporates real time plant and field SCADA
– Divide the service area into District Metering Areas
– Real time meter readings from customers meters and District Metering areas
– Aggregated customer data and comparison to District meter data helps focus leak efforts on high value targets
Consolidate data into one database, offers use data and pattern to customers.
Piloting with existing metering
– New York Regulators assess penalties if lost water exceeds certain ratio, provides incentive if better than certain ratio.
Water Loss – Smart Metering
11
Research and Development
Dedicate more than $90,000,000 per year to R&D
65 different water R&D programs worldwide
Examples:
– Use of biogas to fuel car engines and fuel cells
– Study of the Use of Micro-Algae in Wastewater Treatment Process
– Treats waste stream
– Produces useable energy
– Algorithms to Select Pump systems for Improved Efficiency
– Real time measurement of water bacteriological quality
– Electronic Nose to measure online odor emissions
– Anaerobic digestion using termites
