Disaster Management and Black Sky Events

Coming this October, AWWA will host a webinar entitled Water Sector Black Sky Resilience. A Black Sky event is a long-duration, widespread power outage that could, in turn, cause a whole host of additional catastrophes. 

According to The Electric Infrastructure Security Council, A Black Sky event can have many causes: high magnitude earthquakes, severe space weather, electromagnetic pulses or interferences in the upper atmosphere (the kind that a nuclear detonation might cause), hurricanes, cyber-terrorism, coordinated power grid assaults and more.

Hurricane Harvey has offered a glimpse of the impact a Black Sky event would have on water and wastewater systems and the communities they serve. Black Sky events would cause much longer-term outages than the typical hazard event, and help might not come as quickly, or as easily. Back-up generators might be able to provide a certain amount of power, as long as they are in working order, but what if the treatment chemicals you depend on run out and can't be delivered to you?

Last year, the National Infrastructure Advisory Council issued a 212-page report analyzing water sector disaster scenarios and these types of cascading failures - power losses that lead to water losses and the consequences of those losses. The report concluded that this was an area that needed more analysis and planning. The report also recommends that smaller systems be provided with training as well as assistance in partnering with larger utilities that have more resources. 

Clearly, the effects of a long-term water outage on public health could be devasting, and this is why it is important to incorporate Black Sky response and recovery considerations into disaster management plans. The good news is that if you have a disaster management plan in place, you are already heading in the right direction. Using tools such as this 2016 E-Pro Handbook II (Water), you can expand your plan to include even the most severe emergencies. And this resource form the U.S. Energy Information Administration can keep you updated with live energy disruption reports across the nation. 

The USEPA also has a whole host of tools to help your utility prepare for a Black Sky event including a Power Resilience Guide for Water and Wastewater Utilities, a Drinking Water and Wastewater Utility Generator Preparedness guide, and a video entitled "Power to Keep Water Moving" (click below to view). Finally, be sure to check out the U.S. Army Corps of Engineers' EPFAT tool, a secure web-based tool to input and store emergency power assessment data. Using this tool can help USACE provide temporary power faster, getting you the right generator at the right time.
