Featured Video: TXWARN Tabletop Exercise

Most areas of the country will have to deal with a large-scale disaster at some point. Whether it's an earthquake, blizzard, hurricane, tornado outbreak, flooding, or large-scale drought, most regions are great places to live until they're really, really not. Water utilities play a vital role in disaster scenarios, whether they're ensuring the delivery of clean, safe drinking water or safely removing and treating wastewater. Unfortunately, just because these services are vital doesn't mean they'll remain unaffected in a disaster scenario. In 2005, the experiences of New Orleans during Hurricane Katrina drove home just how vital utilities are to the disaster response process. However, many utilities are not used to their role as emergency responders, and may not have a plan in place if their services were needed in the event of a disaster.

One way to plan for a disaster before you're in the midst of it is to participate in a tabletop exercise. In a tabletop exercise, the major players in a disaster event---police, fire, utilities, mayor, emergency response coordinator---all sit down together and consider step-by-step how they'd respond to a specific disaster if it hit their hometown. It helps to be specific: What if the tornado hit the water tower on the way into town? What if the main road through town was blocked with debris? What if there was a power outage? Specific questions like these can help you think about your resources and emergency planning in more detail.

One very detailed introduction to disaster response tabletop exercises begins with today's video. In 2011, the state-level disaster response agencies for the state of Texas met with TXWARN and tried to plan a response to a fake hurricane, as described to them by facilitators from the consulting group Horsley Witten. The exercise begins with the "hurricane" still out at sea while the agencies at the table think through how they would need to plan depending on where the hurricane makes landfull. It progresses through landfall and widespread rain and storms, and concludes with the participants talking about the exercise and identifying things they could change or improve to plan for a real emergency. This first video is an hour and a half long, and the entire run of the exercise comes to a little over 6 hours of video. But even watching selections from the videos will give you an idea of what kinds of problems and solutions might be worth considering for your own utility's disaster planning.

The Unique Challenges of Wildfires for Water Systems

Recent wildfires in California’s Sonoma and Napa Counties have caused loss of life and significant damage not only to over 5,700 homes and businesses, but also to critical water infrastructure in the region.

In Santa Rosa, residents have been instructed to use only bottled or boiled water for drinking and cooking. According to the city's water engineer, the system is currently experiencing unusually low water pressure, due either to high volumes being used by firefighters or damage to infrastructure. She explains that when water pressure drops below a certain level, backflow prevention devices – particularly in the higher elevations of the system – many not work properly.

Loss of pressure is only one of the many unique and harmful effects wildfire can have on water systems. This 2013 Water Research Foundation report on the effects of wildfire on drinking utilities lists many more, especially the dramatic physical and chemical effects on soils, source water streams and water quality that would necessitate changes to treatment operations and infrastructure. In fact, according to the US EPA, long-lasting post-fire impacts (especially flooding, erosion and sedimentation) can be more detrimental to water systems than the fire itself. 

The WRF report also suggests mitigation and preparedness strategies for utilities, including using fire behavior simulators to identify areas to target for fuel reduction activities, such as this goat grazing program in California. The idea behind such collaborative programs is that the less vegetation fuel available for fires to consume, the better. 

The increase in wildfire incidents such as these across the country make it all the more important for water systems of all sizes to be prepared for the unique challenges of wildfires. A good way to start your preparation is by checking out WaterOperator.org’s listing of free wildfire resources by typing in the word “wildfire” in the search box.

No time to lose? The US EPA has a page of "rip & run" resources including this Wildfire Incident Action Checklist.

Hurricanes, Flooding and Wastewater Plants: What Have We Learned?

In recent months, there have been dozens of reports of wastewater treatment plants that have flooded due to heavy hurricane rains and storm surges in Florida, Texas, Puerto Rico and beyond. Both the sheer number of plants affected, and the extent and duration of the flooding have posed significant public health and technical challenges, often stretching communities to their limits. 

To add to these problems, many rural utilities were already struggling to keep their systems operating before the storms struck, so costly, complicated repairs or replacements of damaged infrastructure is simply not an option. For example, Patton Village, Texas had just completed a new wastewater plant — the first of its kind in their community — before Hurricane Harvey struck. Now they can only hope that USDA/FEMA emergency funding will be available to help repair the damage. And even once the systems are up and running again, it is not a given that water systems can count on water rate income to help with their O&M bills - many residents have fled their flood-damaged homes for good.  

The sad truth is that lately, floods have been affecting wastewater plants with unfortunate regularity, and not just in hurricane-prone areas. For example, in Central Illinois, the small town of Hutsonville's wastewater treatment plant has flooded 3 times in the last 2 years, up from once every 5 years, according to its contract operator Shannon Woodward of Connor & Connor, Inc.

Woodward's first piece of advice is not to build on a floodplain, but he also acknowledges that many communities do not have the capital funds for effective protective measures or relocation, and so operators must deal with the hand they are given. His second piece of advice: "Make sure all electrical controls, switch gears and transformers are above the flood stage. That way, when the flood waters subside, you don't have equipment loss and can get back into operation — even if it takes 3 to 6 weeks for the waters to recede." 

Mason City, another small town in Illinois, was able to fund improvements after a flood in 2008 cut off the town’s water supply and nearly overflowed the capacity of its wastewater system. The following year, the city built a stone wall around the water plant, installed flood sensors on the local river, and built effluent pumping stations for the wastewater plant. 

And this article tells the damage and recovery stories of two flooded wastewater plants in Rhode Island. According to the operators of these plants, it is essential to have a flood plan, even if you think your facility is protected. In addition, they maintain it is important to involve wastewater treatment personnel in emergency response exercises or in the incident command structure. On a practical level, the operators encourage SCADA systems to be elevated on the second floor in the operations building if possible. And lastly, they recommend you back up your files and documents electronically. Papers get wet, they say: move them to a dry storage facility. 

Finally, while every community has different characteristics and needs, there are some universal preparedness strategies for wastewater plants. The US EPA recommends practicing mitigation options as the best way to prevent floodwater from invasively appearing. Some of these options include crafting barriers around key assets, having an emergency back-up generator, and keeping key electrical equipment elevated. You can learn more about these options here, or you can watch this helpful video. In addition, many states have their own guidances, such as this one from Minnesota’s Pollution Control Agency.

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.

Featured Video: Rural Missouri Climate Adaptation

Though it may still feel like spring, depending on where you are in the country, summer is just around the corner. And with summer comes the possibility of drought. Is your utility at risk of drought conditions? Do you know what you'd do if a drought visited your community? Occasional but severe weather events can feel hard to plan for, but not planning at all can make the situation worse. In this 2-minute video, a small rural community in Missouri talks about the planning efforts they're taking on to be prepared for drought in the future, after a particularly tough 2012. Interestingly, their plans to combat drought mesh well with their concerns about sediment in their source water supply as well.

If you'd like to learn more about climate adaptation planning for your utility, check out the tools available through the EPA's Climate Resilient Water Utilities portal, and in particular their risk assessment tool.

Drought Resources for a Dry Summer

If you live in Alabama, Georgia, South Carolina or parts of the Southwest, your utility may be facing drought conditions this summer. Recently, we’ve shared resources for setting rates to encourage water conservation, gaining community buy-in through social marketing, and helping customers track their water use through smart metering.

Yet if you’re not sure yet what your utility needs, you can find a start-to-finish planning guide in the EPA’s comprehensive Drought Response and Recovery Guide, which provides worksheets, best practices, videos and key resources for responding to drought. The guide is paired with an interactive map of case studies of small and medium-sized drinking water utilities in the U.S. that have successfully responded to drought. Video interviews of utility managers and officials will walk viewers through how these towns located emergency resources and then built up their long term resilience.

Rural development specialist Dean Downey of RCAC recommends four steps below to developing a water shortage contingency plan.

Step 1: Establish your utility priorities. The EPA and USDA's Rural and Small Systems Guidebook to Sustainable Utility Management lists ten key management areas of sustainably managed utilities.  By addressing priority areas such as product quality, financial viability, operation resiliency, and others, water system managers can address challenges and increase their effectiveness.

Step 2: Identify your potential water shortage events. Drought, water quality degradation, or equipment failure can reduce or eliminate supply. Water treatment or distribution system failure can also cause major water shortage events. Events can be natural, man-made, or due to equipment failure. As utility system personnel you will most likely have the best idea where to focus your limited resources in planning for water shortages.

Step 3: Assess risks. Don’t spend your time on events that probably won’t occur or that will have limited impact on your utility. Assess both the likelihood and impact of a failure to evaluate the risks.

Step 4: Involve other stakeholders. Don’t forget to include other agencies and groups in the process. Utility personnel are prone to believe they can handle just about any incident. This may be true to a certain extent, but usually utilities underestimate available resources and abilities needed to handle larger or more complex water shortage events.

Downey writes that additional steps include, examining water supply and demand, identifying trigger mechanisms for implementing the plan, and ensuring financial and legal backing.

You can view a full list of RCAC materials for drought planning here, including the Action Plan for Emergency Drought Management, a template for water systems serving fewer than 3,300 people to help assess a drought situation and take immediate actions to mitigate its impact on the community.
