A collapsed sewer pipe beneath the Potomac River became one of the largest sewer spills in U.S. history. Maryland's top environmental official says it should be treated as something more than an isolated failure.
Speaking at the Reservoir Center's World Water Day event, Maryland Department of the Environment Secretary Serena McIlwain called the Potomac Interceptor collapse a "wake-up call" and a "national warning" about the state of aging water infrastructure across the country.
➡️ The Potomac Interceptor: A National Warning
The interceptor that failed was built in 1962. McIlwain said the incident exposed a challenge facing utilities nationwide: critical infrastructure is aging faster than communities can afford to replace it.
"If you have an interceptor that was created back in the 1960s, and it collapsed in the nation's capital, that's a wake-up call."
➡️ The Infrastructure Funding Gap
McIlwain stressed that utilities are not ignoring the problem. Water systems, states, and federal agencies are planning and investing, but the scale of need continues to outpace available funding.
"The federal government, the state government, we are trying to fund and find money. But it just seems like... sometimes the funding doesn't go to the aging infrastructure."
➡️ Data Centers, AI, and New Water Demands
The conversation also turned to the rapid growth of AI and data centers, which are creating new demands on water and energy systems. McIlwain said Maryland is working to balance economic development, community concerns, and environmental protection through permitting, public engagement, and long-term planning.
"Technology is important. We need data centers. It's just where and how are the questions that we ask."
➡️ From Reactive to Proactive
Asked how communities can avoid future crises, McIlwain pointed to modern infrastructure, early warning systems, and new technologies that can identify problems before failures occur.
"We have to stop being reactive and be more proactive when we're planning."
➡️ Why Representation Matters
As the first Black woman to lead the Maryland Department of the Environment, McIlwain reflected on how lived experience shapes environmental policy, from drinking water access to neighborhood inequities and climate resilience.
"It makes a difference to have us sitting at the table."
