Resiliency: American Water Keeps Life Flowing

Flooding in the Midwest, droughts and fires in the West and increasingly intense storms throughout the East and across the U.S. have created operational challenges for many utilities. American Water’s employees and systems have remained resilient in the face of these extreme weather events, as well as cyber and physical attacks directed at the company’s infrastructure. These challenges seem to be increasing in their frequency and have the potential to place strain on our critical infrastructure and impact the lives of all water customers.

Proactive planning and having a strong resiliency plan is an imperative for utilities to address these events. Resiliency as defined by Merriam-Webster is "an ability to recover from or adjust easily to adversity or change." The industry recognizes that successful responses to a changing operational landscape require an ongoing commitment of resources and planning, collaboration with regulators and stakeholders, as well as communications with customers. As the largest and most geographically diverse water company in the country, American Water has extensive experience in confronting the challenges to the industry.

Investment in Resiliency of the System and Customers

A significant portion of our nation’s water infrastructure is nearing 100 years of age, and investment is paramount in order to maintain and enhance the resiliency of these water systems. The American Society of Civil Engineers (ASCE) issued a report in 2021 that concluded that “the system is aging and underfunded.” The nation’s infrastructure was graded a D+. Drinking water and wastewater was graded a C- and D+, respectively. The Value of Water and ASCE’s 2020 economic study, “The Economic Benefits of Investing in Water Infrastructure: How a Failure to Act Would Affect the U.S. Economic Recovery,” found that the annual drinking water and wastewater investment gap will grow to $434 billion by 2029.

American Water’s infrastructure investments increase the ability of our systems to withstand extreme weather events, physical and cyber- attacks and the next potential threat that lies just over the horizon. It also enhances the performance of our systems during and after natural and man-made events and aims to minimize impact to the lives of our customers.

Below are several core aspects of American Water’s resiliency strategy:

  • Investment. American Water plans to spend 10-12% of its total projected capital investment on resiliency over the next five years. This translates to approximately $1.15 billion for the renewal and improvement of the company’s assets.

  • Monitoring The company utilizes the Utility Resiliency Index (“URI”), a uniform water system resiliency metric, to track enhancements around the company’s ability to prepare for and respond to events that impact operations. By 2030, the company intends to increase its URI weighted average by 10% from 2020 baseline.

  • Asset-Hardening. American Water builds flood walls and flood-proof assets beyond anticipated flood levels and deploys emergency power systems to address electric service interruptions. American Water also works to avoid cascading failures across the utility space by implementing back-up electrical systems. For instance, the company recently completed a $15 million emergency power generation system at its Raritan Millstone Water Treatment Facility designed to keep the plant operational in the event of a power failure.

  • Disaster Preparedness. American Water regularly engages with state and federal policymakers, regulators, and other stakeholders to plan for resiliency challenges and so-called “Black Sky Days” – long-duration disruptions that can stem from extreme weather events, natural disasters or man-made attacks on critical infrastructure.

  • Cybersecurity Measures ImageCybersecurity Measures. Water utilities have been the target of cyber-attacks, which could impact service and threaten the health and safety of customers. In February of last year, a small municipal water system in Oldsmar, Florida was subject to a cyberattack. Hackers infiltrated the municipal water utility’s computer system and gained access to the system that automates the type of chemicals to be added during the treatment process. Luckily, no harm occurred as an employee discovered the issue. In June of 2021, a San Francisco water system suffered a cyberattack where the hacker, using the username and password of a former employee, remotely accessed the plant’s computers and deleted important programs. Water is not only an essential service, but it is the only utility that provides a service that is ingested by customers. The White House recognizes the importance water plays in society. Last year, President Biden invited our CEO, Walter Lynch, and other industry leaders to join him and members of his cabinet in a resiliency conversation


State Action to Address Water Resiliency

Several states have passed laws aimed at bolstering the cyber and physical security of water systems. New Jersey was one of the first states to design such a law. New Jersey’s Water Quality Accountability Act sets forth a number of requirements that water systems with 500 or more connections must meet to continue the consistent provision of water services across the state. Included among these criteria is the requirement to develop a cybersecurity plan and conduct regular risk assessments in order to be aware of any cyber threats and vulnerabilities. This type of legislation directly benefits customers and communities as they hold all water providers to the same standards. Indiana and Missouri passed similar legislation in 2018 and 2020, respectively.

We applaud these efforts and stand ready to work with legislators and regulators across our footprint to develop similar frameworks so that all consumers are protected and served by resilient water systems.


Spotlight: Interview with Suzanne Chiavari Director, Engineering Treatment & Asset Resiliency

1. What is asset management and how does it contribute to American Water’s resiliency strategy? Asset management is the practice of managing the life cycle of infrastructure (capital assets). Proactive asset management has many benefits including helping utilities to make more informed decisions, enhance efficiency, manage service risks, and prioritize limited financial resources with the goal of maintaining sustainable infrastructure during normal operations and extreme weather and/or man-made events.

2. From a technology perspective, how is American Water preparing for projected increases in extreme weather, natural disasters, and climate variability? Water and wastewater infrastructure is part of the nation’s critical infrastructure. As such, the vulnerability to extreme weather is a risk that we manage every day. Many water facilities are located near rivers or streams, and sometimes are located in remote areas. Our water systems planning process evaluates how to protect our existing facilities from increasing risks and how to adapt designs for facility upgrades, recognizing that extreme weather conditions may intensify over the next 25-100 years. We continue to deploy new technologies to address these new challenges as well. For example, the company began utilizing drones to inspect facilities after extreme weather events. Drones also allow us to inspect assets that are not readily accessible, such as water storage tank roofs, water or sewer pipelines under bridges or on piers that cross ravines and streams.

3. What do you see on the horizon with regards to asset-related technologies to enhance the resiliency of the American Water system, e.g., identify lead service lines, water acoustics testing, etc.? American Water has tested and deployed acoustic technologies to assess the condition of pipelines for a number of years. This technology continues to advance and we will see more potential uses in the future. Recently, we used this technology to find smaller leaks on water pipes, potential blockages in sewer mains and to measure remaining wall thickness of iron pipe segments. The next challenge is to find or deploy technologies that can also distinguish pipe material (i.e., lead, steel, etc.). American Water is currently participating in this research.

We also use advanced hydraulic modeling and GIS technology for assessing water distribution systems and sewer collection systems. Hydraulic models, which have been a “go-to” tool for engineering studies for many years, can now integrate with the company’s treatment plant Supervisory Control and Data Acquisition (SCADA) systems. This will enable real time model simulation of water systems that can be used to troubleshoot system issues and assist in emergency response.


Utility Preparedness

The utility industry continues to enhance the resilience of its system by anticipating and identifying potential disruptions through the deployment of advanced technologies. As Suzanne Chiavari shared, the company also focuses on the physical hardening of our infrastructure in order to have assets that can rapidly recover from such events. Our investments also extend to providing training for employees that maintain our daily operations, employing new and enhanced measures to keep our employees safe, as well as the customers we serve.

Future editions of the Pipeline newsletter will highlight initiatives aimed at informing and educating our customers on the availability of customer-centric programs. At American Water, we keep life flowing.
