Practical Mitigation
Options for Flood
Resilience
Prevent Intrusion of Flood Water
• Implement a program to keep all drains and culverts
clear of debris to reduce possible flooding.
• Use sandbags to make a quick and low-cost barrier
to minor flooding. Have sand and bags available.
• Install flap valve on low-lying overflow pipes to
protect finished water.
Protect Assets and Operations
• Secure or elevate chemical and other tanks to
prevent them from floating away, releasing
contents, or damaging other equipment.
• Plan to move vehicles to high ground. Develop
alternative methods to access the facility if entry
is blocked by high flood waters or debris.
• Elevate or relocate instrumentation, electrical
controls, computers, and records.
Ensure Power Reliability
• Contact your local power utility and local emergency
management agency to plan for priority restoration
of power to your water or wastewater utility.
• Ensure backup power for pumps, treatment
facilities, and remote units. Purchase, rent, or
borrow generators (e.g., through mutual aid).
Install connections to enable your utility to
rapidly hook up generators to your system.
• Make sure generators, electrical connections,
and fuel supplies are protected from flooding
(e.g., elevated, easy to access).
• Arrange for priority access to fuel supplies
(e.g., vendor contract).
