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?

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

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
