Defend Your Water System Against Drought

Many states across the United States are currently experiencing one of the worst droughts in American history. Some are even experiencing a "megadrought", meaning that they have been experiencing drought conditions for many years. Climate change also exacerbates drought conditions by increasing the average global temperature and causing irregular weather patterns. Westerns states such as California, Arizona, Montana, Nevada, New Mexico, and Idaho are experiencing some of the most extreme effects. Drought is particularly devastating because it is slow coming but its effects are widespread.

Increased drought conditions can result in:

• Loss of water pressure and supply 
• Poor water quality 
• Limited access to alternative water sources 
• Increased customer demand 
• Increased costs and reduced revenues 

For example, in Nevada, the drought has had disastrous impacts on Lake Mead, the largest water reservoir in the United States that currently provides water for over 20 million people across California, Nevada, Arizona, and some of Mexico. The reservoir is now at the lowest it has been since it was filled in 1937 and the situation is so extreme that the federal government is expected to declare an official Lake Mead shortage by the end of the summer. Drought can also negatively impact drinking water providers that rely on lakes because they can increase the number of algal blooms in freshwater. Algal blooms not only contain chemicals that are toxic to humans but large amounts of algae can also clog water filters and damage the water treatment process. 

A total of 31 states are currently experiencing moderate to severe drought across the country. Research also shows that the drought has become progressively worse over the past few decades. The U.S. Drought Monitor website has a feature that allows you to monitor the level of drought happening in your area.

Like most natural disasters, rural and low-income communities are often hit the hardest by drought conditions because of their lack of access to resources and infrastructure. Rural farmers are also greatly impacted by drought because of the lack of water available for irrigation, making it very difficult to support themselves. 

Droughts are a public health issue because they affect access to clean and safe drinking water. Practicing emergency response and preparedness is the best way to minimize severe impacts from drought. To avoid serious impacts from droughts, water utilities should:

1. Conduct observation and monitoring 
2. Practice planning and preparedness  
3. Predict and forecast 
4. Maintain good communication and outreach with customers 
5. Use interdisciplinary research and applications

Featured Video: Drought Response and Recovery in the Town of Castine, ME

This week's featured video tells the story of how  the small town of Castine, ME headed off recent drought and infrastructure challenges - a story that may be adaptable to other small systems nationwide. This video is featured on the USEPA's Drought Response and Recovery StoryMap Project for Water Utilities (ArcGIS) and is included as a case study resource in their recently updated Drought Response and Recovery Guide for Water Utilities guide. 

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.

Better ERPs Part 3: Are You Prepared for a Drought?

For those of us outside the arid West, it can be easy to push aside droughts and their impacts as something others have to worry about. But a look at the U.S. Drought Monitor quickly reveals that droughts—even long-term ones—are a concern coast-to-coast. In fact, increasing temperatures and changes in rainfall patterns are exposing more and more communities to the risk of droughts and other extreme weather events.

Incorporating a drought contingency plan into your broader emergency response plan is one of the best ways to ensure your public water system is prepared for water shortages and other drought impacts. And there are a number of resources available to help you do just that.

The templates and guides below can help you design a plan that meets your system and community needs. Whether you use one of these or create your own, keep in mind these seven steps to an effective drought management plan. These were developed by the Rural Community Assistance Corporation based on the model used by the Texas Commission on Environmental Quality.

1. Seek public involvement by forming a committee of stakeholders who encourage and support a public "buy-in.
2. Define goals and objectives, such as targets for reduced consumption, identifying which customers can and should be restricted and which cannot, legal requirements, minimum flow requirements, etc.
3. Assess supply and demand—identify all existing and potential water supply sources and balance these against average and peak demand, historic demand trends, use by customer sector, interior vs. exterior use, and projected future demand.
4. Define a system-specific drought index, such as ground and/or surface water storage, stream flows, soil moisture, rainfall deficit, well drawdown levels, and other indices.
5. Identify potential mitigation measures, such as water audits, alternative supplies, leak detection and repair, public education, restrictions/bans on non-essential use, pricing disincentives (surcharges), and, finally, rationing.
6. Assess potential impacts of mitigation measures, such as reduced revenues, customer acceptance, rate equity, legal implications, history, and implementation costs.
7. Develop and implement the plan using the management strategies, templates, and statistics assembled during the assessment process.
