Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.
- The Rime of the Ancient Mariner, Samuel Taylor Coleridge
While water is always among our most precious and sensitive natural resources, its value is never more apparent than when you don't have it, such as during hurricanes, flooding, and other disasters. At times when the woes of the ancient mariner wash ashore and the streets are inundated with undrinkable water deep enough to navigate rescue boats, the water management system is at both its most vulnerable and valuable.
Nothing brings this into focus like the recent spate of monster-sized storms battering the southeast corner of our nation. As millions dig out in Texas and Florida from Hurricanes Harvey and Irma, respectively, the nation needs to pull together to help them out and to re-examine our own situations in case we're the next in line for some form of climatic chaos.
The Environmental Protection Agency (EPA), in the aftermaths of Hurricanes Sandy and Katrina, have performed extensive studies and compiled some disaster-preparedness recommendations and an "Incident Action Checklist" specifically for the protection of water systems.
Some of the hazards posed to water systems leading to service interruptions, the EPA points out, include:
Pipe breaks due to washouts, up-rooted trees, etc., which could result in sewage spills or low water pressure throughout the service area
Loss of power and communication infrastructure due to high winds
Combined sewer overflows (CSOs) due to flooding
Restricted access to facilities and collection and distribution system assets due to debris and flood waters
Loss of water quality testing capability during the storm due to restricted facility and laboratory access and damage to utility equipment
During what EPA calls "Superstorm" Sandy in October 2012 utilities from Florida to Maine were very active in monitoring and preparing for its landfall. More than 690 drinking water and wastewater utilities across 11 states and Washington, D.C., experienced impacts from the storm. But much more than drinking water is affected. When Water systems aren't functioning, neither are toilets, showers, washers, dryers, etc
Here are some of the key steps that can be taken to help prepare your local water system for tough times and disasters:
Have a list of emergency contact phone numbers handy (waterproofed/laminated), including resources such as:
Actions to prepare for hurricane season, including (partial listing):
Review and update emergency response plans (ERP)
Identify priority customers (hospitals, assisted living centers, schools, etc.)
Conduct joint tabletop or full-scale exercises
Establish communication protocols and equipment to reduce potential miscues during the actual event
Actions to Respond to a Hurricane: Pre-Landfall Activities (partial list):
Secure equipment; move electronics, equipment, and important data to watertight facility or out of flood-prone areas
Protect exposed lines or pipes that may become vulnerable due to streambank erosion
Consider how evacuations or limited staffing due to transportation issues will impact response procedures
Identify possible staging areas for mutual aid crews if needed in the response, and the availability of local facilities to house the crews
Actions to Respond to a Hurricane: Post-Landfall (Drinking Water Utilities, partial list):
Inspect utility and service areas for damage due to debris, downed trees, and flood waters
Ensure proper pressure is maintained throughout the system and isolate those sections where it isn't
Isolate and control leaks in water transmission and distribution piping
Monitor water quality, develop a sampling plan and adjust treatment as necessary
