Power Resiliency at Water Utilities: What States Can Do Lauren Wisniewski U.S. Environmental Protection Agency ASDWA Webinar August 5, 2015
2
Power Resilience Guide for Drinking Water and Wastewater Utilities
3
Communication Get your utility on the priority list for power restoration Have 24/7 contact information for your electric and gas utilities, emergency management agency, and EOC Verify that electric utility has physical locations of critical components
4
Communication Engage in joint training and exercises Share emergency response plans Discuss options to increase power resiliency, such as tree trimming and an express feed
5
Communication: State Primacy Agency & EMAs Coordination on how water is addressed in State Emergency Response Plan Joint training and exercises Staffing water desk in state EOC
6
Power Assessments Determine power requirements for critical equipment during a power outage Use a qualified electrician Enter information into EPFAT
7
Generator Considerations Sizing Buy, Rent, or Borrow Transfer Switches Fuel Type Placement Maintenance
8
Generator Tips and Lessons Learned Proactively go off grid before storm Have generator needs ready to share with EOC Keep small generators on trailers Keep basic supplies and spare parts on hand Have back-up for your back-up power Running generators in parallel at sites needing >500kW
9
Fuel Storage Tank Sizing Incorporate fuel management into maintenance schedule –Clean fuel tanks –Gel and fuel additives –Fuel polishing unit Refill tanks
10
Fuel Distribution Have multiple refueling options –Contracts with several local vendors –Utility trucks with fuel tanks Minimize energy use when using generators
11
Energy Efficiency Install energy efficient equipment to reduce energy needs and increase power resiliency Set up energy efficiency audit with electrical provider Utilize variable frequency drives (VFDs), screw pumps in the aeration system, and other equipment to decrease energy requirements
12
On-site Power Wind Mills Fuel cells Solar panels Combined Heat and Power
13
Funding Drinking Water and Clean Water State Revolving Funds Fed FUNDS
