Change our Mind(set)

• WEF believes that wastewater treatment

plants are NOT waste disposal facilities, but

rather water resource recovery facilities that

produce clean water, recover nutrients (such as phosphorus and nitrogen), and have

the potential to reduce the nation’s

dependence upon fossil fuel through the

production and use of renewable energy.

Energy Summit

• Raleigh, NC

• March 28-29, 2012

• 30 invited participants from the water and power industries

• Outcome

– Energy Roadmap

Energy Roadmap Purpose

• To help utility

managers effectively

plan and implement

efforts to enhance

energy sustainability

• Build off of the wealth

of existing

information

COMMUNICATION AND OUTREACH

Communication and Outreach

• Identify target

stakeholders

• Tailor the approach

• Evolve and grow efforts

Customers and Community ● Regulatory and

Legislative ● Media Outreach ● Environmental

Advocacy Groups ● Water Sector

Tips:

• Be proactive and create the story

• Emphasize the project benefits (stakeholder specific)

• Share lessons learned within the sector

DEMAND SIDE MANAGEMENT

Demand Side Management

• Review Data– 2 years of bills

• Analyze Costs– Energy charges

– Demand charges

Reduce Energy Use of Key Equipment By:

� Shutting down

� Operate part time

� Operate with variable speed

� Operate at lower flows

� Operate at lower pressures

� Replace with more efficient equipment

Demand Side Management

• Understand Influent Loading

• Manage Loads to Reduce Energy Use– Reduce Inflow/Infiltration

– Industrial surcharges

• Manage Loads for Energy Production– Incentives for trucked high-strength

waste
